[HPADM] SUMMARY: Internal disk on N-class machine

I received some more replies to my previous SUMMARY, all confirming that replacing the disk can be done online. Thanks to Albert Pereira, Illgen Steve, Dave Johnson, Marlou Everson.
Actually there are two words that I was not aware of:
A) hot-swappable: the disk is changed online (with power still on) and the data will be restored/recoverd by the system.
B) hot-pluggable: the disk can be changed online (with power still on) but the system will not do anything about restoring the data etc.
So in this case my question was whether the disk is hot-pluggable.
Since I got downtime, I managed to replace the disk online. Yes, the disk is indeed hot-pluggable.
Here is what I did:
# lvreduce -m 0 /dev/vg00/lvol /dev/dsk/c2t6d0 (do this for each LV)
# vgreduce vg00 /dev/dsk/c2t6d0
Replace the disk
# mkboot /dev/rdsk/c2t6d0
# mkboot -a "hpux -lq" /dev/rdsk/c2t6d0
# vgextend vg00 /dev/dsk/c2t6d0
# lvextend -m 1 /dev/vg00/lvol /dev/dsk/c2t6d0 (do this for each LV)
Regards,
Edi

I got 4 replies from Ted Fisher, Jim Naylor, James J. Perry and Richard Aranas. Thanks.
2 say it's hot-swapable, and 2 say it's not. So I am not really convinced.
Since it's a production server, I called HP, and they say: it's hot-swapable but HP doesn't recommend replacing it online. So I don’t want to take a risk doing it online.
Regards,
Edi

Hi Admins,
Just to get confirmation from you all.
The mirror disk of vg00 (internal) is faulty. Just wondering if the disk is hot-swapable, i.e. can be replaced online.
Model: N4000
OS: HP-UX 11.00
Regards,
Edi
