These instructions are more for SCSI, plus it is very rare I shut down a
machine to replace any disk.

BUT with RAID5 an hdiskx could be
3 or more pdisks.

Looks like this won't work with a RAID5 configuration.
what say you?

Here are some tips ::
Any time you are shutting down an IBM box for disk
replacement you ALWAYS want to run rmdev because
cfgmgr will assign a new alias to disk
when system reboots.
For example, because I didn't rmdel -l hdisk0
before we shut down the box & repl hdisk0
when the box came bk up after disk
was replaced the box displayed hdisk0 & hdisk96.


To Chk Device Driver Software Level On IBM:
lslpp -L | grep SSA
Check Adapters On IBM Boxes:
1.  lsdev -Cc adapter

To Get FRU Number on IBM :
lscfg -vl hdisk0
lspv | grep hdisk0
chdev -l hdisk0 -apv=yes
lspv | grep hdisk0
lsdev -Cc disk | grep -i "scsi"
cfgmgr
rmdev -dl hdisk96

find out which process has cpu hung:
ps -ef -o user -o pid -o pcpu -o comm | more
ps -ef -o user -o pid -o pcpu -o comm | grep -v 0. |
more
