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 further 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.
