LVM disk problem

[Jun Zhang_4]

I forgot his name, but only today, he helped me to convert a LVM disk to under VxVM. Then I tried to do the same thing on another disk, and the same procedure stopped working for me.

# vgimport vg00 /dev/dsk/c0t4d0
vgimport: Warning: Volume Group belongs to different CPU ID.
Can not determine if Volume Group is in use on another system. Continuing.
vgimport: Warning: Volume Group contains "4" PVs, "1" specified. Continuing.
vgimport: Quorum not present, or some physical volume(s) are missing.
Warning: A backup of this volume group may not exist on this machine.
Please remember to take a backup using the vgcfgbackup command after activating
the volume group.
# vgdisplay -v vg00
vgdisplay: Volume group not activated.
vgdisplay: Cannot display volume group "vg00".
# vgchange -a y vg00
vgchange: Couldn't activate volume group "vg00":
Quorum not present, or some physical volume(s) are missing.

Well, basically this is saying that the VG you are attempting to import used to reside on a different system and had 4 disks on the other system and you are only trying to import 1 of those disks. Because you are trying to import 25% of the original disks (1 out of 4) you get the quorum not present message.

It appears that the import MAY have worked. Try doing your vgchange with the low-quorum option.

# vgchange -a y -q n vg00

You can then try your vgdisplay.

Sorry, I issued a
mediainit /dev/rdsk/c0t4d0
and it still running, so that that disk is no longer available for vg00.
I should be a little more patient.

Hi,
Seems you have to recreate the volume group now since you did mediainit.
