I have V-Class server running HP-UX 11.11. We had few VGs on the system. I was trying to check vginfoemation giving
vgdisplay -v /dev/vgoracle
it gave me 'bad entry in lvmtab' file.
Upon checking /etc/lvmtab I found every thing was ok. I removed lvmtab and recreated using,
vgscan -a -v command.
But now my problem is in new lvmtab I could not see any enrty for vg00 and info about it. I tried going in lvm maintenance mode and tried vgscan from there also but it doesn't mount any root lv in lvm maintenance mode. I have exportted all volume groups except root VG but still it is not able to generate proper lvmtab file.
Can any one give any solution for this problem other than reinstalling HP-UX? I don't have ignite recovery tape also.
Thanking you in advance

Re: /etc/lvmtab file corrupted
TG, Pareh says that he doesn't have anything in his lvmtab file even after vgscan.
i don't know whether he is doing vgscan as root or as a user.
top of it no ignite recivery tape. I doubt recovering this m/c

Re: /etc/lvmtab file corrupted
At present this server is not running any major application and this is test server, but since it was some thing strenge I want to know the cause of it.
I am attaching the lvmtab file which is having some /dev/ instead of vg00 and the disk it shows is my boot disk only.
I am running vgscan through administrator login.
Thank you
Paresh

Re: /etc/lvmtab file corrupted
# vgdisplay -v /dev/vg00
vgdisplay: Volume group "/dev/vg00" does not exist in the "/etc/lvmtab" file.
vgdisplay: Cannot display volume group "/dev/vg00".

Re: /etc/lvmtab file corrupted
After vgscan the boot information might be incorrect due to different order of disks in the new /etc/lvmtab file.Try lvlnboot -R to correct boot information.

Re: /etc/lvmtab file corrupted
I just did this 2 days ago with XP512 Disks on a Brocade SAN. An additional consideration is that 'vgscan' will put all alternative paths for the disks that it finds into the lvmtab. However, if you had not performed a 'vgextend' of these before, any 'vgdisplay' command will complain about the disks.
When you need to do this on a SAN-connected HP-UX Server, you will first need to 'hide' the disk paths that were not previously used in the VG. Once the 'vgscan' has been performed, you can 'un-hide' the alternate disks and add them in using 'vgextend'.
Share and Enjoy! Ian
