Re: ssa raid5 pdisk1 bad.

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

This is my first time I had an ssaraid pdisk1 fail
and just want to verify the steps to replace.
No hot spare on my raid5 at this time.

-------------------
1. rmdev -dl pdisk1
2. IBM tech to replace pdisk1 after identifying it
with the blinking light.
3. run cfgmgr
4. make pdisk1 a hot spare disk.

Is this it?

Thanks,
Joe
