How to import VG ...!!!!

[Justin_132]

Hi Admins,

I gotta data disk. How can I import this in a new server. Neither I have any .map file nor taken any vgcfgbkp. How can I import this VG to recover my data.

SAM -> disks and filesystems -> volume groups -> actions -> import

mkdir /dev/vgxx
mknod /dev/vgxx/group c 64 0x0y0000
0y-needs to be uniq minor number

vgimport /dev/vgxx /dev/dsk/cxtxdx /dev/dsk/cytydy

Justin,

A map file is only necessary if there were non-standard logical volume names used on the disk and you wanted to retain them. If you are happy with the default "lvolN" naming convention, you simply run the commands as Anil (RAC) has given.

Thxs All,

Actually I was not knowing how many LUNs were there before in those VGs. I was having 3 LUNs. Even I dont know how may VGs are there before. Unfortunately I didnt got even a bdf o/p.

In this scenario, I just tried as what RAC said. Created 3 VG (Character Device Files) and imported each LUN in each VGs and things worked.

But this can be wrong if my old VG comprises of more than one LUN. So how could I find the number of LUNs my old VG contains...???

Unless you saved how many luns were there, it is difficult (read impossible) to know that.

After you imported the disks, how many lvols it created?? Check /dev/vgxx/lvol* files.
Can you run and mount them all??
