How to change one boot disk

[Carme Torca]

Hi,

I have one boot disk wrong, and we have to replace it, in one hp-ux 11.11 server.

I would know if is it possible to change it hotplug or its better to stop the server.

Thanks a lot of!
Carmen.

What does this mean "boot disk wrong"?

What is wrong?

If the disk is dead but hot pluggable, consider to change it online according to

If your disk is hot swapable go ahead .
Before removing deactivate physical volume.
pvchange -a n pvname
Remove faulty disk
inserted the new one
ioscan -fnC disk
insf -C disk
vgcfgrestore -n vg00 raw-dev
pvchange -a y pvname
follow normal mirroring procedure.

Hola,

ST373454LC is Seagate Cheetah 73.4 GB SCSI *Internal* Hard Drive, then isn't hot pluggable. If your box is covered by HP service I suggest you report this hardware failure.

rp3440 internal disks ARE hot plug!

[Jose Mosquera]

Torsten, you are right! User must dig inside the case.

Rgds.

[Torsten. · Accepted solution]

disks are accessible from the front, but can be locked inside to prevent removal.

[Jose Mosquera]

Yeap! I tried say this in my past post when mistakenly I've refered "isn't hot pluggable". Not just one shot is required to remove it (remembering big ones boxes). I apologize for the erratic term used. :)

If Carme is comfortable doing this go ahead! else, think about my suggestion.

Best regards
