Try "vgchange -a y /dev/vg76".

hi pete,
will i have the data using this command or will i loose my data?

The VG needs to be activated before you can use the Volume. This normally happens on bootup. No data is modified/overwritten by activating the volume.

The purpose of vgchange is to activate a VG so your data is accessable. So NO your data should not be affected.

However you might want to check /var/adm/syslog/syslog.log and/or /etc/rc.log to see why this VG was activated when your machine booted.

Be sure this is not a cluster volume group. In this case the disk is only visible from the node that runs the package.


In case of a bad disk try to activate in quorum mode:

vgchange -a y -q n vg76

I should add that once you activate the VG you will need to mount the filesystems from this VG. The easiest is to do a

# mount -a

# vgchange -a y /dev/vg76

This begins to look very familiar - I had a similar problem a few weeks ago that was caused by a disc having an unused lvol on it.

I'll try to dig out my notes so I can remind myself what HP told me to do. Meanwhile, you might like to click on my user profile and look at my questions - I asked about it on here and got some good answers.
