RAID Diagnostic Error Codes




RAID Diagnostic Error Codes x270xxxx

The RAID controller error codes identify the type of adapter that failed and where the adapter is located within the system. All RAID controller diagnostic error codes adhere to the following template:

    0DDDPLST
     --+||||
       ||||+-------- Type of RAID controller
       ||||          0 = RAID Controller
       ||||          1 = IBM Fast/Wide Streaming RAID Adapter/A
       ||||
       |||+-------- System slot number for the controller
       |||
       ||+-------- Device LUN (value is always 0)
       ||
       |+-------- Device PUN (value is always 7)
       |
       +--------- 270 indentifies that the failure is in the
                      RAID controller.


Information relative to the failure mechanism experienced is encoded within the Failure ID that's included in the diagnostic's error message. The Failure Id is of the form:

    TTEE
    -+---+
     |   |
     |   +------- Identifies the error and is taken from E & F
     |            registers of the shared register set of the MIAMI
     |            chip.
     |
     +----------  Test number
     TT = 00  Memory Tests (DRAM)
          01  DRAM Test
          10  Transfer logic test
          11  MIAMI chip test
          14  Loopback test (through system memory)
          20  SCSI I/O processor test
          21  SIOP data test
          22  SIOP address test
          26  SIOP local loopback test
          30  SIOP/SCSI-Bus test
          31  SCSI Cable test
          32  SCSI Parity test
          40  MIAMI loopback test
