recreating vg

[ausspc]

Hello every body IM in serious situation with my two HP-ux servers they should be in cluster mode connected with emc cx500 I have database and application on both so what I did ? I removed all vg related to emc path by mistake is that mean my data lost ? If yes what should I do ? and if no and I hope so what should I do also ? Is there any way to recreate them and reconnect them to its origin disks ? I appreciate your kind replies ASAP.

Thank you in advance

Did you just remove the VG?  What about the disks that make up the VG?  If you do an 'ioscan' are all of the LUNs from the EMC array still available to the systems?

If the LUNs are still there you should be able to recreate the /dev/vg directories and the /dev/vg*/group files and then import the disks related to each VG.

Hopefully you have a configuration listing that shows all of the VGs that were on the system and the disks that were a part of each VG.  If so, recreating this should be relatively straightforward.

For more information on importing a VG, have a look at the vgimport man page.
