MAP 3434

Use this MAP to resolve the following problem:

  • Disk unit requires initialization before use (URC 9092) for a PCIe3 controller
The possible causes are:
  • Disk is a previously failed disk from a disk array and was automatically replaced by a hot-spare disk.
  • Disk is a previously failed disk from a disk array and was removed and later reinstalled on a different adapter or different location on this adapter.
  • Appropriate service procedures were not followed when replacing disks or reconfiguring the adapter. For example, not using the Device Concurrent Maintenance screen in iprconfig when concurrently removing and installing disks (see Physical disks) or not performing a normal power down of the system before reconfiguring disks and adapters.
  • Disk is member of a disk array, but was detected subsequent to the adapter being configured.
  • Disk has multiple or complex configuration problems.

Step 3434–1

Identify the affected disks by examining the error log and the Display Hardware Status screen. For details, see Viewing device status.

Go to Step 3434–2.

Step 3434–2

Are there other disk or adapter errors that occurred at about the same time as this error?

NO Go to Step 3434–4.

YES Go to Step 3434–3.

Step 3434–3

Resolve the other errors that occurred at the same time as this error.

When the problem is resolved then go to MAP 0410: Repair Checkout in RS/6000® eServer™ pSeries Diagnostic Information for Multiple Bus Systems.

Step 3434–4

Have the disks or adapter card been physically moved recently?

NO Go to Step 3434–5.

YES Go to Step 3434–6.

Step 3434–5

Is the data on the disks needed for this system or any other system?

NO Go to Step 3434–7.

YES Go to Step 3434–6.

Step 3434–6

There are three possible ways to correct this problem. Perform only one of the following three options:
  • IPL the system or logical partition (it might be necessary to boot into Rescue mode), or reset the adapter by performing the following steps:
    1. Find the SCSI host number associated with the adapter by using the Display Hardware Status screen. For more details, see Viewing device status.
    2. Use the echo 1 > /sys/class/scsi_host/hostX/reset_host command to reset the adapter, where X is the SCSI host number from the previous step.
  • Restore the adapter and disks back to their original configuration. Then, IPL the system or logical partition (it might be necessary to boot into Rescue mode), or reset the adapter by performing the following steps:
    1. Find the SCSI host number associated with the adapter by using the Display Hardware Status screen. For more details, see Viewing device status.
    2. Use the echo 1 > /sys/class/scsi_host/hostX/reset_host command to reset the adapter, where X is the SCSI host number from the previous step.
  • Remove the disks from this adapter

When the problem is resolved then go to MAP 0410: Repair Checkout, in RS/6000 eServer pSeries Diagnostic Information for Multiple Bus Systems.

Step 3434–7

There are two possible ways to correct the problem. Perform only one of these options.
  • Format the disks, as follows:
    Attention: All data on the disk array will be lost.
    1. Run the iprconfig utility by typing iprconfig.
    2. Select Work with disk unit recovery.
    3. Select Initialize and format disk unit.
    4. Select the drives you want to format then press Enter.
  • If the disks are members of a disk array, delete the disk array. See Deleting an IBM SAS RAID disk array.
    Note: In some rare scenarios, deleting the disk array will not have any effect on a disk and the disk must be formatted instead.
