I have a weird problem.
I used a vgdisplay -v vg00 and i get the messages:
vgdisplay: Volume group "/dev/vg00" does not exist in the "/etc/lvmtab" file.
vgdisplay: Cannot display volume group "vg00".
after this a moved /etc/lvmtab /etc/lvmtab.old
and did a vgscan -av know i had an other fault:
vgscan: has no correspoding valid raw device file under /dev/rdsk.
Verification of unique LVM disk id on each disk in the volume group
/dev/vg00 failed.
output ioscan -fnCdisk

Re: vg00 no more in /etc/lvmtab
Looks like one of the disk gone bad.
Well what you can do is just move all backup lvmtab files away from /etc and put them in /tmp.
Then try doing vgscan -a to recreate new lvmtab file.
If it still gives error then find which disk have gone bad using dd command.
# dd if=
See if this tracks any bad block on the disk.
Try this for disk1 also.
Hope that helps.

Re: vg00 no more in /etc/lvmtab
You can try the following...
insf -eC disk
#to recreate device files
vgscan -av
#try creating the lvmtab.
If this fails verify that you are able to access both the hard disks using dd like Bharat suggested.

Re: vg00 no more in /etc/lvmtab
you can restore the vg00 configuration using vgcfgrestore command. First u can list the PVs that are belongs to vg00 from the config(backup)file.
For Ex:
Beta3dev /etc =>vgcfgrestore -n vg00 -l
Volume Group Configuration information in "/etc/lvmconf/vg00.conf"
VG Name /dev/vg00
---- Physical volumes : 3 ----
/dev/rdsk/c2t0d0s2 (Bootable)
/dev/rdsk/c2t1d0 (Non-bootable)
/dev/rdsk/c3t2d0 (Non-bootable)
By default it will take the inf. from the file /etc/lvmconf/vg00.conf
If you want to specify some other file,
Beta3dev /etc =>vgcfgrestore -f /etc/lvmconf/vg00conf.3103 -l
Volume Group Configuration information in "/etc/lvmconf/vg00conf.3103"
VG Name /dev/vg00
---- Physical volumes : 2 ----
/dev/rdsk/c2t0d0s2 (Bootable)
/dev/rdsk/c2t1d0 (Non-bootable)
Once you confirmed that file having enough inf. about your vg00, u can restore vg00 using,
Beta3dev /etc =>vgcfgrestore -R -n /dev/vg00 /dev/rdsk/c2t1d0
Volume Group configuration has been restored to /dev/rdsk/c2t1d0
Note: -R option will restore the config even if the VG is still in active.
Hope this will help you

Re: vg00 no more in /etc/lvmtab
I already tried a vgscan with al the options.
I tried the dd options but no fault messages.
the vgcfrestore give the following output:
vgcfgrestore: Volume group "/dev/vg00" does not exist in the "/etc/lvmtab" file.
Volume Group configuration has been restored to /dev/rdsk/c0t5d0
the disk are fine but still i can't get vg00 in the lvmtab.

Re: vg00 no more in /etc/lvmtab
Something wrong with "c0t6d0"
Now that you have executed vgcfgrestore does command "vgdisplay -v vg00" works and if so can you post the output.
Also try executing "pvdisplay -v /dev/dsk/c0t6d0" and post the output.

Re: vg00 no more in /etc/lvmtab
pvdisplay -v /dev/dsk/c0t6d0
pvdisplay: Couldn't find the volume group to which
physical volume "/dev/dsk/c0t6d0" belongs.
pvdisplay: Cannot display physical volume "/dev/dsk/c0t6d0".
