Hi ,
Quorum not present, or some physical volume(s) are missing

from ur output it seems that its not meeting the quorum condition.

check #vgdisplay -v /dev/vg06
If its not meeting the quorum it will not activate. for meeting the quorum the no of pv in that vg must be present more than 52%

52% ???

>50% is ok.

If this is a package, I would assume this command

# vgchange -q n -a e /dev/vg06

Question is, where is c0t0d0 gone?

Hi,

It looks some pv's are missing from that vg.

Check the status of all pv's belongs to that vg and rectify if some are missing.

Thanks

Hi,

For missing PV please check the syslog.log file is there any hardware failure is there or not.
