MAP 3311

Use this MAP to resolve the following problems:

Array not functional due to present hardware configuration (URC 9020 / 9021 / 9022) for a PCI-X or PCIe controller
One or more disk pairs are missing from an array (URC 9060) for a PCI-X or PCIe controller
One or more disks are missing from an array (URC 9061 / 9062) for a PCI-X or PCIe controller

Step 3311–1

Identify the disks missing from the disk array by examining the error log and the Display Hardware Status screen. For details, see Viewing array status.

Go to Step 3311–2.

Step 3311–2

There are three possible ways to correct the problem. Perform only one of the following three options, listed in the order of preference:

Locate the missing disks and install them in the correct physical locations in the system. Then, IPL the system or logical partition (it may be necessary to boot into Rescue mode), or reset the adapter by performing the following:
1. Find the scsi host number associated with the adapter by using the Display Hardware Status screen. For more details see Viewing the Status of Disks and Disk Arrays.
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.
Delete the disk array. For details, see Deleting an IBM SAS RAID disk array.
Attention: All data on the disk array will be lost.
Format the remaining members of the disk array, as follows:
Attention: All data on the disk array will be lost.
1. 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 wish to format then press Enter.

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