Rebuild a raid device (reconstructs a degraded array):

[root@aixfvb01] /root > sisraidmgr -R -z 'pdisk0 pdisk1'

Resynchronizes array protection.

[root@aixfvb01] /root > sisraidmgr -Y -l hdisk1

Delete a raid disk:

[root@aixfvb01] /root > sisraidmgr -Dl sisioa0 -d hdisk0

Creates stand-alone physical disks. Delete a pdisk an reformat to convert to hdisk (take about 30min for a 145GB disk):

[root@aixfvb01] /root > sisraidmgr -U -z pdisk2
[root@aixfvb01] /root > sisraidmgr -U -z pdisk4

Format a SAS pdisk

[root@aixfvb01] /root > sissasraidmgr -F -z pdisk2

SAS Disk Array Management

Cause
 

- General Help:
# sissasraidmgr -h

- Viewing the Disk Array Configuration:
# sissasraidmgr -Ll controller_name -j1

- Preparing Disks for Use in SAS Disk Arrays:
# sissasraidmgr -P -z disk_list
(For example, # sissasraidmgr -P -z hdisk1 hdisk2 pdisk3 pdisk4)

- Changing pdisks to hdisks:
# sissasraidmgr -U -z pdisk_list

- Creating a SAS Disk Array:
# sissasraidmgr -C -r raid level -s  stripe size -z pdisk_list

- Deleting a SAS Disk Array:
# sissasraidmgr -D -l controller name -d array_name

- Adding Disks to an Existing Disk Array:
# sissasraidmgr -A -l array name -z pdisk list

- Creating Hot Spare Disks:
# sissasraidmgr -H -z pdisk_list

- Deleting Hot Spare Disks:
# sissasraidmgr -I -z pdisk_list

- Displaying Rechargeable Battery Information:
# sissasraidmgr -M -o0 -l adapter_name

- Forcing a Rechargeable Battery Error:
# sissasraidmgr -M -o1 -l adapter_name

- Recovering from Disk Failures:
# sissasraidmgr -R -z pdisk_list

- Viewing the SAS device resource locations:
# sissasraidmgr -Z –o0 –j3 -l adapter_name

- Viewing the SAS device resource information:
# sissasraidmgr -Z –o1 –j3 -l adapter_name

- Viewing the SAS path information for the attached device:
# sissasraidmgr -T –o1 –j3 -l device_name

- Viewing the SAS path information graphically for the attached device:
# sissasraidmgr -T –o0 –j3 -l device_name

After replacing a disk, you don't see an available hdisk, it stays defined
