To this end, MAI's Logistics department is requiring that all orders for replacement parts be approved by National Product Support. Please place your orders with Logistics only after discussing the problem with a National Support Analyst. MAI logistics will place the order with IBM who will in turn ship the part directly to the address you requested. An IBM OEM form will also be mailed to you by MAI Logistics department. Upon receipt of the replacement part, this form along with the defective part should be returned to IBM for proper credit. Note: Parts prefix for RPx7000 parts will be IBxxxxxx, once the warranty period has expired, defectives will be returned to logistics using a new red DMT tag, contact logistics for a supply of these DMTs. Note: Parts are listed in the Common Diagnostics and Service Guide SA23-2687 in chapters 3 & 4, model specific parts (ex. chassis parts) are in the model specific Installation and Service Guide located on site. *** Product Topology Program *** MAI will not be participating in IBM's Product Topology program (where IBM keeps a master database of all RS6000 systems via diskettes from each site).

The console terminal displays boot messages then appears to hang. Diagnostics will display normally on the console. If connected to a RAN (16 port concentrator), no display occurs. Cause: The default setting for the RPx7000 ports expects to see carrier detect unless the forcedcd=enable option is selected when configuring the port. Fix: Use cable which supplies CD or reconfigure the port using the option: forcedcd=enable The following basic program can be used to set all ports to a common setting if OpenBASIC is installed and will set the forcedcd=enable option: 10 REM "CFG_PORTS - CONFIGURES PORTS FOR 8,1,N, 9600 BD, 4313, LOGIN ENABLED 20 begin 30 FOR S = 2 TO 3 ;REM "FOR 'RANS' SA2 AND SA3" 40 FOR X = 0 TO 15 50 LET E$="!mkdev -c tty -t 'tty' -s 'rs232' -p 'sa"+STR(S)+"' -w '"+STR(X)+ 50:"' -a term='4313' -a login='enable' -a forcedcd='enable'" 60 PRINT E$ 70 SETERR 90 80 EXECUTE E$ 90 SETERR 0 100 NEXT X 110 NEXT S Problem 2: A serial port appears to be dead for a while then starts working again (with login prompt). There may be a message on the console terminal "Init Command is respawing too rapidly" at the time the terminal quits working. Cause: The port is deactivated for a period of time (around 2 minutes) when an init respawn failure occurs. One cause of this is the CTL key repeat turned on an CTL-D or CTL-C held down. Fix: Turn off key repeat if on, check cable/terminal. Problem 3: Attempting to move or delete a serial port and get message indicating that the port is busy. Cause: There is a process running on the port, probably is /etc/getty or someone is logged in. Fix: Modify the port to disable login then delete/move the port. # /etc/pdisable ttyx Problem 3: A serial port on a RAN (16 port concentrator) is dead and is correctly cabled & configured. Cause: RAN is hung due to static or noise. Fix: Try disabling and enabling the port, if not successful then power the RAN off/on. This will affect all users on this RAN.

This information is saved per disk drive. If the ELA program detects a disk drive of having excessive errors, it will post an SRN (Service Request Number) to have the disk drive replaced and if the Error Log entries are not cleared the new disk drive will be flagged as defective.

This bulletin mentions the two main types of 4mm tape cartridges and describes methods of identifying them. A. 4mm tape cartridges with no Media Recognition System (MRS). These are identified by a filled-in DDS (DDS) symbol. Note: Attempts to write on these types of tape cartridges on an RPx7000 or RS/6000 4mm tape drive will produce "Write protect failure .." message B. 4mm tape cartridges with Media Recognition System. These tapes are identified by a filled-in DDS followed by four vertical lines (DDS||||) symbol. (The symbol may appear on the upper left-hand corner or upper right-hand corner of the tape cartridge depending on the manufacturer's choice). Note: RPx7000 and RS/6000 2.0G-byte and 4.0G-byte tape drives use only DDS|||| tape cartridges to store data.

Okafor Category: Hardware/Diagnostics Subject: RPx7000 & RS/6000 ADAPTER LOCATION CODES Type : Informational Purpose: To assist the field in recognizing adapter location codes These location codes are used in identifying adapter locations on the RPx7000 and RS/6000 systems. Adapter Location Codes ----------------------- The location code for an adapter consists of two pairs of digits with the format AA-BB, where AA is the location of the drawer containing the adapter and BB identifies the I/O slot of the adapter. A value of 00 for the AA field indicates the adapter is located in the CPU drawer. Any other value for the AA field indicates the adapter is located in an asynchronous expansion drawer. In this case, the AA value identifies the I/O slot that contains the async expansionv adapter. The first digit of the BB field identifies the I/O board containing the adapter. If the adapter is in the CPU drawer, system unit, or asynchronous expansion drawer, this digit is 0 for the standard I/O board or 1 for optional I/O board. The second digit identifies the slot number on the indicated I/O board that contains the adapter. A location code of 00-00 is used to identify the standard I/O board. Examples: 00-03 Identifies an adapter in slot 3 of the standard I/O board and is located in either the CPU drawer or the system unit, depending on the type of system. 00-14 Identifies an adapter in slot 4 of the optional I/O board and is located in the CPU Enclosure drawer. 16-07 Identifies an adapter located in slot 7 of an asynchronous expansion drawer. The drawer is connected to the asynchronous expansion adapter located in slot 6 of the optional I/O board in the CPU Enclosure drawer. USEFUL COMMANDS: 1. The command below displays all the names of the defined adapters, their location codes and a brief description. lsdev -C -c adapter 2. This command automatically configures additional devices that have been added or powered on since the last time the system was booted. cfmgr 3. This command removed the adapter, sa2, but retains its definition in the Customized Devices Object Class.

Okafor Category: Software Subject: RPx7000 & RS/6000 Device LOCATION CODES Type : Informational Purpose: To assist the field in recognizing location codes for devices. These location codes are used in identifying physical devices on the RPx7000 and RS/6000 systems. The location code for a device is a path from the system unit or CPU drawer through the adapter, signal cables, and the asynchronous distribution box or breakout box (if there is one) to the device in question. Depending on the type of device, the location code consists of four fields (AA-BB-CC-DD) representing: i) Drawer or system unit ii) I/O slot with adapter iii) Connector iv) Port or SCSI device address Each field is a two characters long. In general devices have location codes of the format: AA-BB-CC-DD where: AA-BB is the location code of the adapter to which the device is connected. CC is the connector of the adapter.

The following is how to configure this tape drive on the RPX 7000 system : You must first set the SCSI address on the tape drive making sure that this address is not being used on the RPX 7000 (you can use lsdev -C to verify current SCSI addresses). As root run "smit" and select the following : DEVICES / TAPE DRIVE / ADD A TAPE DRIVE and select ost (SCSI Other SCSI Tape Drive), select parent adapter, select Connection Address (SCSI address for tape) and modify the following parameters : Parameter Value NOTES : BLOCK SIZE (0=variable length) [0] DENSITY setting #1 [3] Sets 6250 bpi DENSITY setting #2 [2] Sets 1600 bpi BLOCK SIZE for variable length support [0] Use Device Buffers during writes [yes] Use Extended file marks [yes] Enter 'cr' when done and this will define the tape drive. You can reboot the system and you will see that a new driver in the /dev/rmt* dirrectory has been created (or you can perform lsdev -C). Use this new driver for access to the tape drive.

Terminal Concentrators (128 port controller) The terminal concentrators used on the 128 port controller (RPX 7000 & SCO) have built in diagnostics. These diagnostics can be manually accessed by : Connecting a terminal (vt100 emulation) to port 1 or 16 on the "target" concentrator. Power the concentrator OFF and then ON. When the display shows "P1" enter a "v" at the keyboard and a test menu will be displayed. 2. Digiboard Port Authority The Digiboard Port Authority, "DPA", is a useful utility for the 128 port controller and its concentrators (only for 128 port controller). There is a version of DPA for RPX 7000 and a version for SCO, there are no other versions. DPA will show which concentrators are active and which are "down". The user can select a specific port and see what the interface is doing (Rx data, Tx data, flow control) in the same manner as the LED display. Additionally the DPA will show link speed and characteristics (buad rate, bits, parity) These diagnostics are considered to be self explanatory and no manuals are available. In order to received the DPA utility you must contact MAI customer care center and order MAI part number W400947-003. You will received media that contains two files : dpa.sco (for SCO) and dpa.aix (for the RPX). Example on how to execute dpa.aix : dpa.aix -s1 (will execute dpa.aix if it's in your directory and will check the first 128 port concentrator) end of bulletin.

Type : Informational Purpose : Help the field with a way to configure these ports without having to use "smit" to configure the ports one at a time. When configuring a port on the RPX 7000 system some of the defaults for a tty device are : 8 bits, no parity, 9600 baud, TERM=dumb, login=disable, Alternate RJ-45 Pinouts=disable. If we want to configure all ports on the breakout box with MAI terminals (ex: 4314) with 7 bits, Odd parity, 9600 baud, TERM=4314, login=enable, Alternate RJ-45 Pinouts=enable (when using cable 917005 and adapter 400837-004) you can do this with the following script : Using vi as root create a file : vi filename add the following : for i in 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 do mkdev -c tty -t tty -s rs232 -p sa3 -w $i -a parity=odd -a bpc=7 -a term=4314 \ -a altpin=enable -a login=enable done save the file. To execute the script type : sh filename Note : sa3 is the port adapter for the 16 RAN port (you can find the name of of your RAN port by doing : lsdev -C |more), the "\" after 4314 indicates the command continues on the next line). To configure another 16-RAN port just change the -p option with the next sa number (sa4 for example). The options that are standard defaults that will remain the same do not need to be changed (in our example the baud rate will remain 9600). If you want to configure a printer just go into "smit" and remove the tty port (including database definition) and then configure the port as a printer. For more info on mkdev please refer to the man pages (man mkdev). NOTE: You will probably want to add the 'forcedcd=enable' attribute to the above script, refer to the BASIC program to set ports in FIB 5 of this group.
