First of all, AIX does not care about the hdisk names. This is just a
convenience to you. I'd leave it hdisk17 and get on with life, but if you
really want to change the name, here's one way (without having to
manipulate the ODM directly - very dangerous)
Assuming rootvg is on hdisk0 and no paging space is on any of the SSA
drives...
Shut down everything except AIX. Unmount all filesystems except those in
rootvg.There must be no activity on any of the disks except for hdisk0.
Remove the disk information from the ODM:
for PV in $(lsdev -C | egrep '^hdisk|^pdisk' | awk '{print $1'); do
rmdev -dl $PV
done
Re-discover the disks (repopulate the ODM):
cfgmgr -v
rmdev will remove the disk information for all the pdisks and hdisks except
for hdisk0 (you'll get an error message regarding hdisk0 because it's busy
- ignore this). cfgmgr will now find the new internal disk before it
discovers the SSA disks and name it hdisk1.
Once cfgmgr is done you can bring up all your applications.

Subject: How to rename HDISKxx?
> I have a J50 with one internal SCSI drive, hdisk0, and 16 SSA drives,
hdisk1-hdisk16. I added a second internal SCSI drive, which,
understandably, became hdisk17. I would prefer the second SCSI drive to be
hdisk1 rather than hdisk17. Short of physically pulling the SSA drives &
running cfgmgr, is there any way to rename these drives? TIA.
