LVM Root replace

bagek — Tue, 29 Nov 2011 02:13:22 GMT

I have a rp2470 with a bad vg00 mirrored root disk. I shut the system dwon and replaced the failed disk. It got claimed. Should I use these commands to attach it to vg00? I've done it before but not on the root. HPUX 11.23 Thanks.

Replacing a bad disk with MIRROR:

# vgcfgrestore -n /dev/vgXX /dev/rdsk/cxtxdx
# vgchange -a y /dev/vgXX (to make v.group available)
# vgsync /dev/vgxx (resync logical volumnes)

Replacing a bad BOOT disk with mirror:

# vgcfgrestore -n /dev/vgXX /dev/rdsk/cxtxdx
# vgchange -a y /dev/vgXX (to make v.group available)
# vgsync /dev/vgxx (resync logical volumnes)
# mkboot /dev/rdsk/cxtxdx
# mkboot -a "hpux -lq" /dev/rdsk/cxtxdx
# shutdown -yr 0 (Test the replaced disk)
