a) Press F3 to return to the IBM SAS Disk Array Manager menu.
b) Select Reconstruct a SAS Disk Array and press Enter.
c) Select the pdisk that you want to reconstruct, which should be the drive that you just installed.
The array is rebuilt.
18. To verify the drive, continue with step "23" on page 30.
19. If the state of the array is Failed or Missing, delete and recreate the array. Then, restore the data
from the backup.
Attention: All data on the disk array will be lost.
To delete the array, complete the following steps:
a) Start the IBM SAS Disk Array Manager. From the AIX Diagnostics, select Task Selection > RAID
Array Manager > IBM SAS Disk Array Manager.
b) Select Delete a SAS Disk Array > IBM SAS RAID Controller.
c) Select the disk array to delete.
20. To recreate the RAID Array and restore data from the backup, complete the following steps:
a) Select Create an IBM SAS Disk Array.
b) Select the IBM SAS RAID Controller on which you want to create an array.
c) Select the RAID level for the array. For more information about selecting an appropriate RAID
level, see Supported RAID levels (www.ibm.com/support/knowledgecenter/POWER9/p9ebj/
sassupportedraidlevels.htm).
d) Select the stripe size in kilobytes for the array. For more information about the stripe-size
parameter, see Stripe-unit size (www.ibm.com/support/knowledgecenter/POWER9/p9ebj/
sasstripeunitsize.htm).
e) Select the disks that you want to use in the array according to the requirements displayed on the
screen and press Enter.
Note: To reduce the creation time of the new array, format and zero the drives using the Create an
Array Candidate pdisk and Format to RAID block size function before creating the new array.
Data must be restored from a backup disk. The disk array can be added to a volume group. Logical
volumes and file systems can also be created. Use the standard AIX procedures to complete
these tasks, and use the array in the same way that you would use any hdisk.
21. To verify the drive, continue with step "23" on page 30.
22. To rebuild a drive by using the Linux operating system, complete the following steps:
a. Log in as root user.
b. Type iprconfig on the command line of the Linux session and press Enter.
c. Select Work with disk unit recovery > Rebuild disk unit data.
d. Type 1 (Rebuild) next to the drive you want to rebuild and press Enter.
Note: Completing a rebuild on a drive overwrites the data currently on the drive.
e. To confirm that you want to rebuild the data on the drive, press Enter. A message is shown when
the rebuild starts. The rebuild process might take several minutes to complete.
23. Verify the installed part.
• If you replaced the part because of a service action, verify the installed part. For instructions, see
Verifying a repair (www.ibm.com/support/knowledgecenter/POWER9/p9ect/
pxect_verifyrepair.htm).
• If you installed the part for any other reason, verify the installed part. For instructions, see Verifying
the installed part (www.ibm.com/support/knowledgecenter/POWER9/p9haj/pxhaj_hsmverify.htm).
