Re: Missing volume group
# vgchange -a n /dev/vg01
Deactivates vg01 and any associated lvol
-> replace physically the disk
# vgcfgrestore -n /dev/vg01 /dev/rdsk/cxtyd0
gets configuration information from a specified source
#vgchange -a y /dev/vg01 ( reactivates the vg)
#newfs -F vxfs(hfs) /dev/vg01/lvolx
( recreates att the lvol on the damaged disk)
# mount /dev/vg01/lvlox /mount_pointx
mounts the file systems
-> recovers data from backup

Re: Missing volume group
it really sounds as if you have lost a disk.
Here are some tips for troubleshooting:
- ioscan -fnC disk ... does disk still show up?
- dd if=/dev/dsk/
- check dmesg output
- have a look at /var/adm/syslog/sylog.log and OLDsyslog.log
- if possible run the diagnostics with stm
But in any case you need to contact HP anyways to replace the disk. Let them help you to deteremine if the disk broke on you

Re: Missing volume group
You can check wich ones they are by executing "vgdisplay -v vg01" or lvdisplay -v to each lvol.
good luck.

Re: Missing volume group
I had a similar problem before, I had 3 2gigs with 3 lv's in 1 vg, running progress with 4 very large databases, then one morning bam! 1 lv was gone...with no apparent reason, come to fing out, 1 of the drives was bad and since the data was striped, needless to say I lost everything, but was I ever thankfull for a prior backup, and hopefully you have one, cuase I think you'll need it, hopefully this is not your problem also, but it could be worth the investigation to find out...if it is, your data is probably gone, if not I dont know what else info to offer.Hope this helps...Tony
