Replace Primary boot disk at HP-UX Wednesday, February 6, 2008
Posted by piyut in HP-UX.trackback
I have experience and case about “primary boot disk failed” at HP-UX 11.11. The server is superdome [hp high end server]. There are PVs stale at primary boot disk, the secondary disk [alternate boot disk] doesn’t have PV stale. My hp engineer recommended to replace the disk offline. Hoho…server is production and downtime is limited! I tried to search in goggle and sign in to itrc.com [hp forum] and i found the answer. I can replace primary boot disk failed in online replacement. Below, the steps i have done to replace my primary boot disk:
1. try to break mirror, but failed
2. unplug the bad disk
3. plug the new disk:
# vgcfgrestore -n /dev/vg00 /dev/rdsk/c0t0d0
vgcfgrestore: Cannot restore Physical Volume “/dev/dsk/c0t0d0″,
Detach the PV or detactivate the VG, before restoring the PV.
# pvchange -a n /dev/dsk/c0t0d0
# vgcfgrestore -n /dev/vg00 /dev/rdsk/c0t0d0
# pvchange -a y /dev/dsk/c0t0d0
# vgchange -a y /dev/vg00
# mkboot -l /dev/dsk/c0t0d0
# mkboot -a “hpux -lq” /dev/rdsk/c0t0d0
# lvlnboot -R –> vg automaticaly sync data
Rebooting server is needed if we want to check the new disk to booting.

Hi Piyut!
I don’t believe that these instructions would work on an Itanium server. Am I right?
#ddouthitt: yup, maybe! you can find at itrc.com. I have not more knowledge in Itanium server.
