I have a volume group on a server with a single lvol. The lvol is currently mounted to the server:
/dev/vgDBNAMEhome/lvol1 24.9g 14.8g 10.0g 60% /u01
vgdisplay reports:
[finux203:/etc/lvmconf] vgdisplay /dev/vgDBNAMEhome
vgdisplay: Volume group "/dev/vgDBNAMEhome" does not exist in the "/etc/lvmtab_p" file.
vgdisplay: Cannot display volume group "/dev/vgDBNAMEhome".
We are using Netapp storage and the SAN utilities also can't tell me anything about the storage. vgscan doesn't detect it if I mv the lvmtab file(s) and rescan.
Now it appears that the kernel knows what this is, as I can mount/unmount it just fine. Is there a way to pull the volumegroup information from the kernel/memory?
As a side note, whoever imported this space did not run the vgbackup command as I don't see a .conf file. There are no backups of the lvmtab(s) that contain this vg.
Thanks for any help.

Re: VG in kernel memory but not lvmtab files
Sorry for the extraordinary time to reply to this, but Sajjad's reply ended up being the correct answer. The directory for the volume group was present, but another administrator had removed the group file and moved the lvmtab off. After recreating the group file with the correct minor number I was able to get vgscan to detect the volume group.
