Verifying the 12X loops without an HMC

If your system is not managed by a Hardware Management Console (HMC), learn how to use the IBM® i, AIX®, Virtual I/O Server (VIOS), or Linux operating system to verify that the 12X loops have no failed links.

1. Choose the operating system that best applies to your configuration.
   Important: Multiple options might apply to your configuration. Choose only the first option that applies.
   • If your system has a partition running VIOS operating system, continue with step 2.
   • If your system has a partition running the AIX operating system, continue with step 3.
   • If your system has a partition running the IBM i operating system, continue with step 4.
   • If your system has a partition running the Linux operating system, continue with step 6.
2. Use the VIOS error log to verify that there are no B70069xx errors (where x is any character 0 - 9 or A - F) by completing the following steps.
   1. Log in as the padmin user. If you need assistance, contact the system administrator.
   2. Type diagmenu -d sysplanar0 -E xx and press Enter, where xx is any number 1 - 60 that specifies a number of days. This command returns results for the most recent number of days specified. The suggested range is 30 days.
   3. Highlight the Problem Determination option in the DIAGNOSTIC MODE SELECTION display. Press Enter.
   4. Search the results that are displayed to identify problems with B70069xx reference codes. You might need to scroll down in the display to see all of the results.
      Note: If the Problem Determination results contain serviceable events that have already been reported, a PREVIOUS DIAGNOSTICS RESULTS display appears. Respond to the Do you want to review these previously reported errors? prompt by highlighting the YES response, and then press Enter.
   5. Based on the results of your search, perform one of the following options:
      • If there are no problems with B70069xx reference codes, press Enter to return to the command line.
      • If there are problems with B70069xx reference codes, there might be problems with the 12X loops. Perform problem analysis on the problems to correct them before continuing. If you need assistance, contact your service provider.
   6. Go to step 7.
3. Use the AIX error log to verify that there are no B70069xx errors (where x is any character 0 - 9 or A - F) by completing the following steps.
   1. Log in as the padmin user. If you need assistance, contact the system administrator.
   2. Type diag -d sysplanar0 -E xx and press Enter, where xx is any number 1 - 60 that specifies a number of days. This command returns results for the most recent number of days specified. The suggested range is 30 days.
   3. Highlight the Problem Determination option in the DIAGNOSTIC MODE SELECTION display. Press Enter.
   4. Search the results that are displayed to identify problems with B70069xx reference codes. You might need to scroll down in the display to see all of the results.
      Note: If the Problem Determination results contain serviceable events that have already been reported, a PREVIOUS DIAGNOSTICS RESULTS display appears. Respond to the Do you want to review these previously reported errors? prompt by highlighting the YES response, and then press Enter.
   5. Based on the results of your search, perform one of the following options:
      • If there are no problems with B70069xx reference codes, press Enter to return to the command line.
      • If there are problems with B70069xx reference codes, there might be problems with the 12X loops. Perform problem analysis on the problems to correct them before continuing. If you need assistance, contact your service provider.
   6. Go to step 7.
4. Use the IBM i service action event log to verify that there are no B70069xx errors (where x is any character 0 - 9 or A - F) by completing the following steps.
   1. Sign on with at least service level authority.
   2. On the command line of the IBM i session, type strsst and press Enter.
   3. Type your service tools user ID and service tools password on the System Service Tools (SST) Sign On display. Press Enter.
      Tip: The service tools password is case-sensitive.
   4. Click Start a Service Tool > Hardware Service Manager > Work with Service Action Event Log.
   5. On the Select Timeframe display, change the From: Date and Time to the desired date and time range. The suggested range is 30 days.
   6. Search for serviceable events with B70069xx reference codes, and perform one of the following actions:
      • If there are no serviceable events with B70069xx reference codes, press F3 (Exit) to return to the Hardware Service Manager display. Go to step 5
      • If there are serviceable events with B70069xx reference codes, there might be problems with the 12X loops. Perform problem analysis on the serviceable events to correct the problems before continuing. If you need assistance, contact your service provider. Go to step 7
5. Use the Hardware Service Manager to verify the statuses of the links in the 12X loops by completing the following steps:
   1. Type your service tools user ID and service tools password on the System Service Tools (SST) Sign On display. Press Enter. The service tools password is case-sensitive.
   2. Select Logical hardware resources from the Hardware Service Manager display. Press Enter.
   3. Select High-speed link resources from the Logical Hardware Resources display. Press Enter.
   4. Select Display port information for the first 12X loop. Press Enter.
   5. Scan the port information screen to identify rows with links that must be repaired. A row must be repaired if the connection status is a value other than Operational.
      Exception: Do not include any rows belonging to a loop with no I/O expansion units connected. The port information display shows a loop with no I/O expansion units as a single row that contains a connection status of Failed.
   6. Choose one of the following options:
      1. If you completed step 5.e without identifying any links to be repaired, press F3 to exit.
      2. If you completed step 5.e with one or more links that are not Operational, then the rows that you identified contain failed or degraded links in the 12X configuration. The links must be repaired before you continue. To repair the links, repeat step 5.e. If you already performed step 5.e or need assistance, contact your next level of support.
   7. Go to step 7.
6. Use the Linux error log to verify that there are no B70069xx errors (where x is any character 0 - 9 or A - F) by completing the following steps.
   1. Log in as the root user. If you need assistance, contact the system administrator.
   2. To list every platform error with a reference code that starts with B70069, type servicelog --query='refcode like "B70069%" AND serviceable=1 AND closed=0' and press Enter.
   3. Search the results that are displayed for problems with B70069xx reference codes and for statuses that are open. If there are problems with B70069xx reference codes, there might be problems with the 12X loops. Perform problem analysis on the problems to correct them before continuing. If you need assistance, contact your service provider.
      Note: You might need to scroll down in the display to see all of the results.
   4. Go to step 7.
