I do not know what i have to do to return all the volum groups ?

Note I already do vgimport !
Any Idea please ?

See where you went wrong is when you did the vgcfgrestore
when you do the vgcfgrestore you should supply all the disk which were in that volume group not disk one by one as you have done that has corrupted the volume group configuration on the disks.

And vgimport wont happen till the disks are in /etc/lvmtab
Now there is very little you can do to restore the lv and data. What you can do is export the volume group
1. vgexport
2. mkdir /dev/
3. mknod /dev//group c 64
and vgimport
4. vgimport /dev/ <....all disks to be included in VG>
5. If vgimport doesn't work then you have to create the VG again and then all lv and restore the data from backup.
vgcreate /dev/ ....all disks...
lvcreate ...

Thanks

hi,
are there any other disks, from another chain ?

What is this storage? Is it possible that you used some disks that belongs to a vg on another server ?

Please post a full (if not already so)

strings /etc/lvmtab

and ioscan -fnCdisk


I suspect that you re-used some disks..

Another thing: in the output it comes:

"/dev/dsk
/c2t3d0":


on two rows, can you confirm this ? i suspect also some corruption in lvmtab or vgda/vgra structures...

From your other thread i see:


http://forums.itrc.hp.com/cm/QuestionAnswer/1,,0xfaf43ac61301774ba24b37ec56774b38,00.html

that you had other vg.

Check the minor number !

ll /dev/vg*/group

to see if they are unique

Hi

I think that you have a problem with lvmtab so run vgscan in preview mode and if the output is ok run it for update lvmtab

# vgscan -p -a -v

# vgscan -a -v

good luck

It seems your lvmtab got corrupted. Do the following steps to rectify the problem

1) mv /etc/lvmtab /etc/lvmtab.org
2) vgscan -a -v

The above command will recreate lvmtab file. Now you check your vgdisplay command.
