Jones MAGNETIC TAPE I/O-BASIC FOUR-4407,4409,HCC,MT44,etc-FIB001 Pg001 FIB 00002 03/23/90 *** HCC Hardware Announcement [ WPSH 28 ] *** The HCC (MT-4407) is a high performance, high capacity 8mm cartridge tape drive with advanced helical scan technology. This yields an extremely high recording density and storage capacity of up to 2.0 gigabytes. The Type 3 Load Image backup is the only support for this unit, configured on an MPx and Advanced Series. SPx systems support all tape commands. The storage media is a re-writeable 8mm precision magnetic tape housed in a reel-to-reel cartridge measuring 3.75 X 2.5 X 0.6 inches. Data is written on the tape using helical scan techniques. This media is 'Certified' for data use, not to be confused with video camcorders 8mm cartridges. Currently, only the EXABYTE 8mm 2048 'Data Cartridge' is certified for use in the HCC tape unit. EXABYTE is the only approved Cleaning Kit (PN 750013-001). This may be one of two types; Wet or Dry. The Wet version was first approved; in the future the Dry version will only be available. In either case, do not use the Cleaning Kit more than indicated on the kit. This, more than likely, is a total of three (3) cleanings. To use the Cleaning Kit past the indicated amount may cause the end of the cleaning tape to to pull off the hub and travel past the HCC heads. This will cause the sticky adhesive of the tape end to contaminate the head and may necessitate a unit replacement. The HCC is supported on the MPx 9xxx and Advanced Series systems, along with SPx systems. The HCC will support image and file-by-file backup types on the SPx and only image on MPx and Advanced Series. It is an external unit that may be daisy-chained to the GCR or MTS 1/2-inch tape units supported by the BMTC PCBA. When daisy-chained, only one tape unit per BMTC may be used at a time. A tape boot cannot be performed with this tape unit.

Revision R is the lowest revision level required to support the HCC; other system constraints may require the BMTC PCBA to be at higher revisions. Revision R is also required for full MTCS support. Revision U is required for GCR support, and revision Z is required for the Advanced Series System. See Section 1.3 for HCC switch settings. BMTC/Tape Unit ID - (Refer to figures 1,2, and 3) Selection is done via switch SW3 at location 9A. This lets the BMTC know which unit ID's are attached. This switch provides cable present status without the need of cables being attached to the BMTC. SW3-1 thru SW3-4 determine 1/2-inch and HCC tape ID's as follows: SW3-1 = 1/2" or HCC unit ID #0 SW3-2 = 1/2" or HCC unit ID #1 SW3-3 = 1/2" or HCC unit ID #2 SW3-4 = 1/2" or HCC unit ID #3 NOTE: These are individual settings, not a binary count. For two tape units attached to the same BMTC (HCC with MTS or GCR) for unit ID #0 and ID #1, SW3-1 and SW3-2 must be set (On). The tape units must have ID #0 and ID #1 set respectively. SW3-5 thru SW3-8 determine the 1/4-inch unit ID. In this case both tape units could have ID #0 but are differentiated by being a 1/2-inch or 1/4-inch unit. SW3-5 = 1/4" unit ID #0 SW3-6 = 1/4" unit ID #1 SW3-7 = 1/4" unit ID #2 SW3-8 = 1/4" unit ID #3 NOTE: These are individual settings, not a binary count. BMTC/Tape Unit Parity - Parity selection is done via switch SW2 at location 2S. SW2-7 selects the option of either External Parity or Internal Parity. SW2-7 Closed - External parity selected. Correct parity supplied by BMTC for tape transport. Correct parity checked by BMTC from tape transport. NORMAL SETTING. SW2-7 Open - Internal parity selected. Tape unit generates and checks its own parity internally. If position 7 is set to open, the BMTC will report hard errors continuously. MTS Unit ID/Parity - Selection is done via Address Line Decoding Switch at location U8W. This switch is used to set the MTS Unit ID and External/Internal parity. U8W-1,2 and 4 - Selects MTS Unit ID, binary count ADDRESS 0 - 1 - 2 - 3 U8W-1 0 0 0 0 0 = ON U8W-2 0 0 1 1 1 = OFF U8W-4 0 1 0 1 MAGNETIC TAPE I/O-BASIC FOUR-4407,HCC,MT-4407,M,etc-FIB002 Pg002 U8W-5 and 6 - Selects option of External or Internal Parity. U8W-5=On and U8W-6=Off = External Parity. NORMAL SETTING. U8W-5=Off and U8W-6=On = Internal Parity. This setting is used with the TDP PCBA only. Not with HCC/BMTC. GCR Unit ID/Parity - Selection is done via switch #2 (KC47) on the CP Card. This switch is used to set the GCR Unit ID, there is no parity setting. SW2-9 and 10 - Selects GCR Unit ID, binary count. ADDRESS 0 - 1 - 2 - 3 SW-9 0 0 1 1 0 = ON SW-10 0 1 0 1 1 = OFF 1.2 SPX The tape controller (P/N 903639-002) for the HCC unit is identical to the half-inch tape controller (P/N 903629-001) except for the 'PROM' located at position '7H' on the PCBA. The jumpers on the PCBA are set in manufacturing; see below. JUMPER LOCATION JMP 1 PINS (1-2) JMP 2 PINS (1-2) JMP 3 PINS (1-2) JMP 5 PINS (2-3) JMP 6 PINS (1-2) JMP 7 PINS (1-2) JMP 8 PINS (1-2) JMP 9 PINS (1-2) JMP 10 PINS (1-2) At this time, two separate tape controllers are maintained: P/N 903639-001 for half-inch tape and P/N 903639- 002 for 8mm tape drives. No system may be configured with both 8mm and half-inch tape controllers. As with all tape controllers, it must reside in the primary chassis of a 4000. (continued on next page) MAGNETIC TAPE I/O-BASIC FOUR-4407,HCC,MT-4407,M,etc-FIB002 Pg003 1.3 HCC SWITCH SETTINGS - MPx/SPx The HCC tape unit has two banks of eight switches. The proper settings are listed below. SWITCH NORMAL SETTINGS HCC UNIT ID 0 - 1 - 2 - 3 * SW1-1 --> OFF ON OFF ON * SW1-2 --> OFF OFF ON ON * SW1-3 --> OFF OFF OFF OFF SW1-4 OFF SW1-5 OFF SW1-6 OFF SW1-7 OFF SW1-8 OFF SW2-1 OFF SW2-2 ON SW2-3 OFF SW2-4 ON SW2-5 OFF SW2-6 ON SW2-7 OFF SW2-8 ON *NOTE: SW1 - 1,2, and 3 set the HCC unit ID; ID of 0 is the only valid setting for the SPx system. See page 2-3 of the HCC Users Guide (M0168A). This is the only switch setting configuration supported by MBF for the SPx systems. 2.0 CABLING 2.1 MPx Depending upon the installation of the HCC, there is a choice of three (3) different pairs of cables to use. The TOTAL length of the daisy-chain cables cannot exceed 50-feet. Using standard MBF cables will insure that this cable length is not exceeded. 1) P/N 916396-001 - BMTC to HCC with no daisy-chaining. 2) P/N 916399-001 - MTS to HCC, allows daisy-chaining. 3) P/N 916398-001 - GCR to HCC, allows daisy-chaining. NOTE: The HCC tape unit is the end unit. The end unit will have terminators to terminate the end of the cable. This means that the HCC must be powered ON when the MTS/GCR is being used, if it is daisy-chained to them. When the HCC is daisy-chained to the MTS/GCR tape units, the MTS/GCR terminators must be removed. The address of one of the tape units must be changed to ID #1, the HCC would be the best one to change the ID on. MAGNETIC TAPE I/O-BASIC FOUR-4407,HCC,MT-4407,M,etc-FIB002 Pg004 TERMINATORS - Terminator locations for the tape units are as follows: (Refer to figures # 1, 2, and 3) MTS - Locations U3W and U10W. GCR - Locations AG17 and BH12. HCC - Located at rear of unit, RN4, RN5, RN8, and RN11. 2.2 SPX To connect the HCC unit to the controller requires two fifty pin ribbon cables (P/N 916485-001). Looking at the HCC unit from the back on the right side you will see two connectors marked 'J1' and 'J2', 'J2' being on the outside. Connect one of the cables to the 'J2' connector with pin one on the bottom edge. Connect the other cable to 'J1' with pin one (pin one of the cable has the red strip) on the bottom edge. Connect the cable from 'J1' on the HCC to the lower connector of the controller with pin one pointing up. Connect the cable from 'J2' on the HCC to the upper connector on the card with pin one pointing up. Refer to page 2-5 of HCC Users Guide (M0168A). 3.0 HCC FAULTS ON MPX AND SPX The Fault indicator on the front of the HCC tape unit indicates a transport. fault condition. The Pertec interface PCBA on the bottom of the unit has no connection to this Fault indicator. If the Fault indicator should come on, or other problems occur (excluding cabling problems) during operation of the backup utility, the following steps should be taken: 1) Clean the HCC tape unit using the APPROVED 8mm Cleaning Kit. 2) Use another 8mm APPROVED tape. 3) If problem continues, do steps 1 and 2 again. 4) Replace complete HCC unit. If the HCC unit should 'eject' the tape, this indicates a Servo problem. Perform the same steps as above. 4.0 SERVICE PLAN ON MPx AND SPx If the HCC tape unit should fail and it cannot be fixed by cleaning the head or replacing the tape, the complete unit will need to be replaced. Do not interchange PCBA's between HCC units, THIS WILL 'VOID' THE WARRANTY! The complete unit is tracked by the serial numbers of each PCBA, if there is any difference in the serial numbers, the warranty is void. 5.0 OPERATING SYSTEM 5.1 MPx The 9/10.6G OS release, or greater, is required for support of this product. The HCC tape unit is intended for Type3Load Family Image backup only. The 9/10/6G OS, or later, supports 'Multi-Family' image backup. This allows multiple families to be backed up to one tape set. The image backup can also extend to multiple tape reels. Please refer to the BOSS/VS Installation Guide (M5138J) for added information on the Type3Load options. MAGNETIC TAPE I/O-BASIC FOUR-4407,HCC,MT-4407,M,etc-FIB002 Pg005 If an error occurs while the program is reading from disk, a sector-by-sector retry of the operation is attempted. If it is successful, the program continues. If not, a message is displayed indicating the type of error and its location. At this point, the user has the option to Retry, Continue, or Abort the operation. An Abort causes the entire copy to be aborted. A Continue causes the operation to continue past the error. If the operation continues, the error will probably be caught and reported again during the compare. When the operator continues with the copy operation, bad data will be saved on tape. This will still allow the restore to complete without any sector mismatch error. However, the image backup should be used only if the disk errors did not affect any critical data on the disk. If any disk error occurs, the user should note its exact location so that the information can be used to determine what track needs to be relocated to correct the problem. NOTE: To archive 'Uninterrupted' operation per 8mm tape (2.0 Gigabytes per tape), the disk/families to be backed up should be 'hard' error free. The OS does a sector-by-sector retry but a 'hard' error will require operator intervention to select Retry, Continue, or Abort options. 5.2 SPx The OS level of the SPx must be 7.5B or greater. In the 'SAVE AND RESTORE' utilities you must use the half-inch tape option to access the HCC tape unit. When using the tape commands directly the 'dev=' parameter must be 'dev=ts' to access the HCC tape unit. The HCC tape unit will support all tape commands and options EXCEPT any type of append and the retension, unload and raw options. The HCC will not support a 'load from tape' and no installable software will be distributed on 8mm media. ORIGINATOR: Don Luque/Steve Binderup MAGNETIC TAPE I/O-BASIC FOUR-4407,HCC,MT-4407,M,etc-FIB002 Pg006 FIB 00003 10/11/90 *** Cabling/Testing/Usage on MPx/ASxx/SPx [ WPSF 633 ] *** Type: Informational/Problem PURPOSE General information on how to CABLE the unit, how to TEST the unit and proper USAGE to prevent button damage. SYMPTOM Improper cabling, testing and usage will cause the HCC tape unit to appear DOA or have excessive faults. CAUSE Cabling - The maximum total cable length from the BMTC to the end tape unit is 40-feet (the end tape unit being the HCC, daisy-chained or not). If the cable length should go beyond this length, HCC faults can occur randomly. SOLUTION Using the correct MBF cables will insure that this cable length is not exceeded. The cable lengths are as follows: CABLES LENGTH TOTAL SPx to HCC P/N 916485-001 12 feet 12 feet BMTC to HCC P/N 916396-001 15 feet 15 feet BMTC to MTS P/N 907065-001 20 feet \ MTS to HCC P/N 916399-001 10 feet / 30 feet BMTC to GCR P/N 907065-004 25 feet \ GCR to HCC P/N 916398-001 15 feet / 40 feet Also insure that the cable ground straps are attached. CAUSE Testing - Improper test selection can cause the HCC tape unit to appear to have several 'variable length record' errors. Thus making the HCC appear to be at fault. SOLUTION DEMON should be used to test the HCC tape unit. The default test does NOT provide enough testing to adequately test the unit. The proper tests that should always be used, but are not limited to, following: TESTS #24 Streaming test (Write): 1 (default is 0) #25 Streaming test (Read): 1 (default is 0) #33 Limit Buffer Size (32K)? Y (this is the default, do not change) Streaming test - The purpose of the streaming test is to verify MAGNETIC TAPE I/O-BASIC FOUR-4407,HCC,MT-4407,M,etc-FIB003 Pg001 the tape/controllers ability to write and read various data patterns while maintaining tape motion. This test begins at BOT then proceeds to write 61K records until EOT is reached. A fixed set of 8 data patterns are repeated while writing. After EOT is detected, the tape is again rewound. At BOT the test proceeds reading all records until EOT is reached. All records read are checked for status errors and data mismatches. Limit Record Size (32K) - This feature was implemented in order to support the limitations of the HCC tape unit. The HCC unit has a 32K record size limitation based upon it's internal handling of data. Selecting this option will limit other selected DEMON test to not exceed this 32K size. To exceed this size will cause 'Variable Length Record' errors. CAUSE Usage - Improper usage (operation) of the HCC unit will cause the 'momentary contact' switches on the front panel to break. This is most likely due to the user being unfamiliar with the characteristics of the HCC unit and the unique feel of the momentary contact switches when depressed. A 'probe' (pencil, pen, etc.) should NEVER be used to depress these switches. The ball of the thumb should be used for those who have long fingernails. SOLUTION Read the MT-4407 High Capacity Cartridge Tape Drive User Guide, M0168. The 'Operator Panel Controls and Indicators' section explains the operation of the HCC unit during power-up cycle, loading a tape and putting it ON-LINE. Between cycles, the HCC unit may not respond to the depression of the switches until that cycle is done. Repeated pressing of the switches will not speed up the time it takes but may lead one to think that it did not recognize the the switch action. It most likely did not if you did not wait for each cycle to complete. Be patient, wait until each phase of the HCC cycle is done. Between each cycle, one or more of the indicators will blink then go out or display a solid light. Some cycles will have a series of blinks then go out. HCC cycle - When first turning ON the unit (without a cartridge in the unit) 3 indicators will blink; FAULT, REWIND/BUSY and ON LINE. This is a lamp test only. After approximately 8 seconds, the REWIND/BUSY indicator blinks once. This indicates that the drive passed internal diagnostics. After this 'blink', you may press the EJECT switch to install a cartridge. Pressing the EJECT switch prior to this will not open the door nor is it buffered to take place after the 'blink'! After inserting a cartridge and closing the door, the REWIND/BUSY indicator blinks. This indicates that the cartridge is rewinding to logical-beginning-of-tape. At this time you may also depress the ON-LINE switch which will start the ON-LINE indicator to blink. This indicates that the unit has accepted the command. At logical-beginning-of-tape, the REWIND/BUSY indicator goes out and the ON-LINE indicator displays a solid light (if it too was depressed). If the ON-LINE switch was not depressed, then you may MAGNETIC TAPE I/O-BASIC FOUR-4407,HCC,MT-4407,M,etc-FIB003 Pg002 do so now. This will start the REWIND/BUSY indicator to blink and the ON-LINE indicator will be a solid light, the REWIND/BUSY indicator will go out and the ON-LINE indicator will remain ON. This indicates that the unit is ready to accept host commands. CAUSE Improper orientation of the switch 'rubber boot' cover will cause the need to repeatedly depress the switch. The repeated depressing of the switch and adding extra force to depress the switch will cause the momentary switch to break. SOLUTION Insure that the 'rubber boot' is orientated properly. Inside of this rubber boot there is a solid rubber edge with a raised 'dot' at one end. This rubber edge passes through the center of the the boot and the raised dot MUST be positioned in the direction of the switch. You will notice that the momentary contact switches are 'offset' from the center line of the hole in the front panel. The raised dot of the rubber boot must be in the same direction of this offset. EXAMPLE: | | __|__ = Centerline _O_|___ ___|_ _ | | | O | | O = Switch o====== ======o ====o = Rubber edge with raised dot. With the unit turned Off, you will hear a 'click' as the rubber edge flicks off the 'momentary contact' switch, if orientated properly. FYI TAPES Tapes - EXABYTE vs EXATAPE 8mm cartridges. Exabyte has changed their tapes to Exatape to achieve continuity with European standards. Exabyte 2048 were rated for 2-hours and were 106 meters in length. When used in Europe, due to the voltage/ frequency difference, the tapes were not achieving this 2-hour limit. Thus Exatape came to achieve this goal. Exatape is a replacement for the Exabyte tapes that were/are currently being used. They are 112 meters in length which now will achieve this 2-hour limit in Europe. Though the Exatape is longer, domestic usage does not allow the usage of the added length (due to the checking done internal of the tape unit). The data storage is the same with Exatape as is with the Exabyte 8mm cartridge.

With the release of 'n.6G' OS release, the HCC tape drive was supported for multiple FAMILY IMAGE backup in the Type 3 Load functions. When a family had to be restored, and was not the first family saved on tape, each family on tape before that family would take the same amount of time to skip past it as it did to 'save' that family. EXAMPLE: Family 1 took A amount of time, Family 2 took B amount of time and Family 3 took C amount of time (excluding the COMPARE times). If you wanted to RESTORE Family 3, it would take 'A'+'B' time to reach Family 3 to start the RESTORE. With revision 'D' of the HCC tape unit, the microcode was changed for a "FAST FILE SEARCH" option. To implement this option also required a change to the m.7A OS as to the way the Family was saved on tape. If the families were saved on the m.7A OS and the HCC tape unit is at revision 'D' and switch SW2-7 is OFF (on the HCC), positioning to a Family on tape is now faster. This change to the revision 'D' microcode does not effect tapes saved on pre-m.7A OS releases. All tapes will still be able to be read by the HCC tape unit. The change to the microcode has also changed the way the front panel LED's display. The REWIND/BUSY LED will continue to 'blink' when the unit is waiting for a command. This difference may lead one who is familiar with the lower revision HCC unit, to replace the revision 'D' unit due to the LED 'blinking'. The REWIND/BUSY LED will blink (awaiting a command) when: 1) A tape cartridge is inserted into the HCC unit and the ONLINE switch has NOT been depressed. After depressing the ONLINE switch, at logical-beginning-of-tape the REWIND/BUSY indicator goes out and the ON-LINE LED will remain ON. 2) At the end of a BACKUP, the REWIND/BUSY LED will remain 'blinking' until the EJECT switch is depressed. After depressing EJECT switch, the REWIND/BUSY LED will remain ON (not blinking), the door will open, then the LED will go out.

These faults can be caused by : I. DATA at the begining of tape. II. SOFTWARE. I. DATA: . SYMPTOM: I.1 After inserting tape, the Rewind/Busy indicator never stops flashing. The unit does not go on-line or the tape cannot be ejected. The need to turn the unit Off/On prior to ejecting the tape is required. I.2 After indicating that the tape has no label and selecting 'Yes' to Initialize the tape, the tape unit goes off-line and the Fault LED flashes. CAUSE: When an 8-mm cartridge is inserted in the tape unit, the unit tries to read the tape label first. If the tape label is corrupted, the above symptoms may be noticed. Todate, there are two different types of label corruption that we know of that can cause the 'Fault LED' to flash. Symptom I.1 occured using 'NEW' tape cartridges from the box ! Analyzing the tapes showed that there was a 'Tone' written at the beginning of tape (BOT). This tone confuses the servo and . locks up the unit. Symptom I.2 occured after replacing a faulty HCC unit that was DOA. After installing the replacement unit, and using the same tape cartridges that were used in the DOA unit, the replacement HCC now 'Faults' when initializing the tape in SAVERESTORE. Even though the MT-4407 is not supported in SAVERESTORE, this utility is a valid test of the unit; the unit should be able to label the tape. In this case, the DOA unit also went into a Fault when trying to label the tape. It wrote corrupted information at the beginning of tape, now causing the replacement unit to Fault using the same tapes. NOTE: The DOA unit failed the Self Test Diagnostics sending the unit into a Fault condition at the beginning of the test. SOLUTION: The MT-4407 unit has a built-in Self Test capability. The Self Test Diagnostics will perform numerious read/write rewind operations till EOT, then rewind and start tests again. NOTE: DO NOT USE A TAPE WITH VALID DATA, IT WILL BE WRITTEN OVER ! MAGNETIC TAPE I/O-BASIC FOUR-4407,4409,HCC,MT44,etc-FIB006 Pg001 Symptom I.1 was resolved by running Self Test for a couple of minutes, allowing the 'tone' at BOT to be overwritten. Symptom I.2 was resolved by putting the unit back on-line after the unit went into the fault as follows in SAVERSTORE: . THIS TAPE HAS NO LABEL INFORMATION, INITIALIZE (Y/N)? 'Y' (next display) WARNING: ALL DATA WILL BE LOST AFTER INITIALIZATION !!! (Rewind/Busy LED flashes @ 30 seconds) DRIVE OFFLINE At this point the Fault LED is flashing. Depress the On-line button, the Fault LED goes out and the Rewind/Busy and On-line LEDs will flash. After a few moments when the tape is rewound, the On-line LED remains On. The cursor will now position to the Tape Label prompts and continue to write the label. Though Self Test was not used to 'condition' the tape, it did prove the DOA unit was indeed bad and not a 'tape issue'. Self Test Procedure: The Self Test Diagnostic is also used by the OEM to help burn-in the unit. The test will run forever until it is stopped or a fault occurs. No host system is required to run this test, it can be run at the office if necessary. 1) Depress the Eject button and wait for the door to open. 2) Turn Off the unit power and set switch S1-4 to ON (down). 3) Insert tape cartridge, close door and power On the unit. 4) When the Rewind/Busy LED starts flashing, depress the On Line button; now both LED's are flashing. Periodically the Rewind/Busy LED will go Off for a few moments then On. II. SOFTWARE SYMPTOM: Using the "UNATENDED" software the Fault indicator on the HCC unit is flashing and BACKUP is not completed. CAUSE : If a printer was selected as the output device and the HCC has an error or sends a message that the software can not recognize, it will cause the HCC unit to fault. When the output is to a printer the error routine in the software is looking for certain errors. If an error or message is not what the software is looking for, it will not send a correct response back to the HCC thus causing a fault. SOLUTION : Select a file (RESULT) as the output device. The software will send all input/output to this file (Including ERRORS/MESSAGES). In most cases the BACKUP will be completed and you will not see the HCC unit fault. After the BACKUP is completed go into CONSOLE MODE and run a program called DISPLAY (this program is looking for a file named RESULT) and it will display everything that occured during the . BACKUP to the VDT, look for any strange ERRORS or MESSAGES. If you see any please send this information to JOE MELENDEZ (OMS I.D. MELENJ) at FPS.

MELENDEZ MAGNETIC TAPE I/O-BASIC FOUR-4407,4409,HCC,MT44,etc-FIB006 Pg003 FIB 00007 MAI COMPANY CONFIDENTIAL 11/23/92 *** Incorrect Firmware on MX & SV PCBAs *** Type: Problem Problem: Firmware matched sets required for the MX and SV PCBA's are not correct. Symptom: Not all symptoms are known pertaining to each system platform that these units are used on. Both the 4407 (Mega Tape) and the 4409 (Exabyte) use the same transport within the unit. Problems could range from not passing DEMON to receiving Console messages indicating that the unit is Busy after operation has started. Cause: The transport, in the 8mm tape units, have two PCBA's that must have a matched set of firmware. The PCBA's are the 'MX' and 'SV' PCBA's. Solution: When a service call is made to a site that involves the 8mm tape unit, remove the outside cover and check the FW levels. On top of the tape transport is a label that contains the FW Revision levels of the PCBA's. The label with the correct FW will contain the following information. FW Rev. MAI PN. MXPROM 262H 165064-002 SVPROM C033 165060-003 If the FW revision levels are not correct, the 8mm unit as a whole will need to be replaced. This FW in NOT field replacable. If the FW revision levels are correct, continue troubleshooting to determine the failure. NOTE: If the FW levels are not correct and the tape unit is replaced, this does not necessarily mean that the reported problem is fixed. It does mean that you now have an updated tape unit and you don't need to concern yourself with these unknown conditions. Eliminate other possibilities by insuring that the 8mm controller, cables, tapes, etc are OK prior to replacement of the tape unit. This FW DOES NOT address any problems that may have occurred. due to turning the tape unit OFF; such as the system hanging. because the SCSI Bus is now hosed. ORIGINATOR: Don Luque MAGNETIC TAPE I/O-BASIC FOUR-4407,4409,HCC,MT44,etc-FIB007 Pg001 FIB 00008 MAI COMPANY CONFIDENTIAL 10/08/93 *** Errors writing labels on SPx Systems [ WPSF 753 ] *** TYPE: Informational/Problem PURPOSE: To report a problem found with the High Capacity Cartridge (HCC) on the SPx and the resolution. PROBLEM: Using tsave (command and utility) after the tape label is written the system will report either a 'timeout' or 'input/output' error. RESOLUTION: The problem is caused by the HCC being at revision D firmware. This problem was introduced when the firmware was changed to handle MPx image backups. To correct this use an HCC at revision C or convert the HCC to revision C. The HCCs being shipped are at revision D, so before installing a new or replacement HCC on the SPx the HCC will need to be converted to revision C. The firmware is located at U56 and U58 on the main logic board on the HCC. The -003 is the revision C, the -004 is the revision D firmware. If the old HCC is still available the revision C firmware can be taken out of it. Otherwise the firmware can be ordered using the following part numbers: MM660035 Revision C firmware (even) MM660040 Revision C firmware (odd) NOTE: Make sure to remark the HCC(s) to the correct revision level.
