Use this procedure to resolve the following problem: Multiple adapters not capable of controlling the same set of devices (SRC xxxx9074)

1. This error relates to adapters connected in a dual storage IOA configuration. To obtain the reason or description for this failure, you must find the formatted error information in the Product Activity Log. The log also contains information about the connected adapter.

   Perform the following steps:

   1. Access SST/DST.
      • If you can enter a command at the console, access system service tools (SST). See System service tools.
      • If you cannot enter a command at the console, perform an IPL to DST. See Performing an IPL to dedicated service tools.
      • If you cannot perform a type A or B IPL, perform a type D IPL from removable media.
   2. Access the Product Activity Log and record address information.

      If a type D IPL was not performed to get to SST/DST:

      The log information is formatted. Access the Product Activity Log and display the SRC that sent you here. Press the F9 key for "Address Information". This is the adapter address. Then, press F12 to cancel and return to the previous screen. Then press the F4 key to view the "Additional Information" to record the formatted log information. The Problem description field indicates the type of problem. The type, serial number, and Worldwide ID of the connected adapter is also available.

      If a type D IPL was performed to get to DST:

      The log information is not formatted. Access the Product Activity Log and display the SRC that sent you here. The direct select address (DSA) of the adapter is in the format BBBB-xxxx:

      BBBB

      hexadecimal offsets 4C and 4D

      xxxx

      Not used

      In order to interpret the hexadecimal information to get device addresses. See Examples: Obtaining additional information from hexadecimal reports. The Problem description field indicates the type of problem. The type, serial number, and Worldwide ID of the connected adapter is also available.

2. Find the problem description and information for the connected 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

   Problem description	Full description	Action	Adapter on which to perform the action
   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 that logged the error. See SAS fabric identification to verify connections.	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. See SAS fabric identification to verify connections.	Remote adapter indicated in the error log.
   Primary lost contact with disk units accessible by secondary.	Link failure from primary adapter to devices. An automatic failover will occur.	Verify the connections to the devices from the adapter that logged the error. See SAS fabric identification to verify connections.	Adapter that logged the error.
   Other	Not currently defined.	Contact your hardware service provider.

   This ends the procedure.
