SIP3110

This procedure resolves problems when disk units are incompatible or a disk unit is missing or failed.

The following SRCs are possible:
  • SRC xxxx9025. Indicates that an incompatible disk unit is installed at the disk unit location that caused the array to be exposed.
  • SRC xxxx9030. Indicates that a disk array is exposed due to a missing or failed disk unit.
  • SRC xxxx9032. Indicates that a disk unit in a disk array is missing or failed, but the array is still protected.
If you received SRC xxxx9030 or xxxx9032, one of the following occurred:
  • A disk unit has failed and the RAID array protection is exposed or will become exposed if another disk unit fails because no hot spare disk unit was available to replace it. If the array is exposed, then the array will continue to be exposed until the disk unit has been replaced and a manual rebuilding of the array has been started.
  • A disk unit has failed in a RAID array, but a hot spare was used to automatically start rebuilding the array. Replace, format, and configure the failed disk unit as a hot spare.
    Note: If the previous hot spare disk unit was a larger capacity than the failed disk unit, ensure that the customer understands that the replacement disk unit might not provide adequate hot spare coverage for all of the arrays under this adapter.
  1. Is the device location information for this SRC available in the service action log (see Searching the service action log for details)?
    No:
    Continue with the next step.
    Yes:
    Exchange the disk unit. This ends the procedure.
  2. Identify the affected adapter and disk units by examining the product activity log. Perform one of the following steps to access system service tools (SST) or dedicated service tools (DST):
  3. Perform the following steps:
    1. Access the product activity log and display the SRC that sent you here.
    2. Press the F9 key for address information. This is the adapter address.
    3. Continue with the next step.
  4. Perform the following steps:
    1. Return to the SST or DST main menu.
    2. Select Work with disk units > Display disk configuration > Display disk configuration status.
    3. On the Display disk configuration status display, look for the devices attached to the adapter that is identified in step 3.
    Is there a device that has a status of RAID 5/Unknown, RAID 6/Unknown, RAID 5/Failed, or RAID 6/Failed?
    No:
    Continue with step 7.
    Yes:
    Continue with the next step.
  5. Find the device that has a status of RAID 5/Unknown, RAID 6/Unknown, RAID 5/Failed, or RAID 6/Failed. This is the device that is causing the problem. Show the device address by selecting Display Disk Unit Details > Display Detailed Address. Record the device address. Go to Addresses and find the following items:
    • The slot that is identified by the direct select address of the adapter
    • The disk unit location that is identified by the device address
  6. Have you determined the location of the adapter and disk unit that is causing the problem?
    No:
    Ask your next level of support for assistance. This ends the procedure.
    Yes:
    Exchange the disk unit that is causing the problem. This ends the procedure.
  7. Press the function key to cancel and to return to the Display Disk Configuration menu, then do the following:
    1. Select Display disk hardware status.
    2. Find a device that is either Not operational or Read/write protected.
    3. Display details for the device and get the location of the failed disk unit.
    4. Exchange the disk unit and configure it as a hot spare. This ends the procedure.
