Use this procedure to resolve the following problem: Multiple adapters not capable of similar functions or controlling 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. This should also contain information about the connected adapter.

   Perform the following:

   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 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 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-Cc-bb:

      BBBB

      hexadecimal offsets 4C and 4D

      Cc

      hexadecimal offset 51

      bb

      hexadecimal offset 4F

      In order to interpret the hexadecimal information to get device addresses. See More 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 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 unit function being used by primary.	Secondary adapter detected a device function that it does not support.	Customer might need to upgrade the adapter code 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 units under each adapter using HSM 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 units under each adapter using HSM 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 connected to the same numbered SAS port on both adapters.	Verify connections and re-cable SAS connections as necessary.	Either adapter.
   Primary lost contact with disk units 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.

   This ends the procedure.
