Verifying the 12X loops with an HMC

If your system is managed by a Hardware Management Console (HMC), learn how to verify that the 12X loops have no failed links.

1. Verify that no serviceable events include B70069xx reference codes (where x is any character 0 - 9 or A - F) by performing the following steps:
   1. In the navigation area of the HMC, select Service Management.
   2. In the content area, select Manage Serviceable Events.
   3. In the Manage Serviceable Events window, perform the following steps:
      1. Click Open for the Serviceable Event Status field.
      2. Select the machine type, model, and serial number (MTMS) of the server you are working with for the Reporting MTMS field.
      3. Click ALL for all other fields, and click OK.
   4. Scan for any serviceable events that include B70069xx reference codes, and perform one of the following actions:
      • If there are no serviceable events that include B70069xx reference codes, close the Reference Code History window.
      • If there are serviceable events that include 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.
2. Verify the status of the links in the 12X loops by performing the following steps:
   1. From the navigation bar, expand Systems Management.
   2. Click Servers.
   3. Select the server you are working with.
   4. From the Tasks area, complete the following steps:
      1. Expand Hardware Information.
      2. Click View Hardware Topology.
   5. Scan the Current Hardware Topology section of the Hardware Topology data to identify rows with links that must be repaired. A row must be repaired if either the Leading Port Status column or Trailing Port Status column contains a value other than Operational.
      Exception: Exclude any rows that represent nodes belonging to a loop with no I/O expansion units connected. The Hardware Topology data displays a loop with no I/O expansion units as a bus with only one associated row. That row contains a Node Type of Local NIC, a Leading Port Status of Open/Failed, and Trailing Port Status of Open/Failed.
   6. If you identified links in step 2.e with a status other than Operational, the links must be repaired before you continue. To repair the links, repeat step 1. If you already performed step 1 or need assistance, contact your next level of support.
