MAP 3141

Use this MAP to resolve the following problem: Multiple controllers not capable of similar functions or controlling same set of devices (SRN nnnn - 9074)

Step 3141-1

This error relates to adapters connected in a Multi Initiator and High Availability configuration. To obtain the reason or description for this failure, you must find the formatted error information in the AIX® error log. This should also contain information about the attached adapter (Remote Adapter fields).

Display the hardware error log. View the hardware error log as follows:

  1. Follow the steps in Examining the hardware error log and return here.
  2. Select the hardware error log to view. Viewing the hardware error log, the Detail Data section contains the REASON FOR FAILURE and the Remote Adapter Vendor ID, Product ID, Serial Number, and World Wide ID.
  3. Go to Step 3141-2.

Step 3141-2

Find the REASON FOR FAILURE and information for the attached adapter (remote adapter) shown in the error log, and perform the action listed for the reason in the following table:

Table 1. RAID array reason for failure
Reason for Failure Description Action Adapter on which to perform the action
Secondary does not support RAID level being used by primary. Secondary adapter detected that the primary has a RAID array with a RAID level that the secondary does not support. Customer needs to upgrade the type of secondary adapter or change the RAID level of the array on the primary to a level that is supported by the secondary. Physically change the type of adapter that logged the error. Change RAID level on primary adapter (remote adapter indicated in the error log).
Secondary does not support disk function being used by primary. Secondary adapter detected a device function that it does not support. Customer might need to upgrade the adapter microcode or upgrade the type of secondary adapter. Adapter that logged the error.
Secondary is unable to find devices found by the primary. Secondary adapter cannot discover all the devices that the primary has. Verify the connections to the devices from the adapter logging the error.

View the disk array configuration screens to determine the SAS port with the problem.

Adapter that logged the error.
Secondary found devices not found by the primary. Secondary adapter has discovered more devices than the primary. After this error is logged, an automatic failover will occur. Verify the connections to the devices from the remote adapter as indicated in the error log.

View the disk array configuration screens to determine the SAS port with the problem.

Remote adapter indicated in the error log.
Secondary port not connected to the same numbered port on primary. SAS connections from the adapter to the devices are incorrect. Common disk expansion drawers must be attached to the same numbered SAS port on both adapters. Verify connections and re-cable SAS connections as necessary. Either adapter.
Primary lost contact with disks accessible by secondary. Link failure from primary adapter to devices. An automatic failover will occur. Verify cable connections from the adapter which logged the error. Possible disk expansion drawer failure. Adapter that logged the error.
Other Not currently defined. Contact your hardware service provider.  

When the problem is resolved, see the removal and replacement procedures topic for the system unit on which you are working and do the "Verifying the repair" procedure.
