Volumn group not activated

[jackizm]

Hi All
There is a error output when I use the command "vgdisplay".

vgdisplay: Volumn group not activated
vgdisplay: cannot display volumn group "/dev/myvg01"

Who could tell me the reason?

Thanks a lot!

[Sunil Sharma_1]

try to run

#vgchange -a y /dev/vg01

This will activate volume group vg01

then

#vgdisplay -v vg01

Hi Jack,
This definitely means vg01 is not activated on your system. You can activate this VG as told above but you need to check whether it is active on any other system if it is on shared storage.

Is this is a Cluster Node??

Hi

#vgchange -a y /dev/myvg01
#vgdisplay /dev/myvg01

If this node is in a cluster, you definitely want to check that this vg is not active on another node before you activate it. During a "clean" failover of a package, all vg's should be exported, so they wouldn't normally show up on another node in the cluster, but this kind of thing can happen if the failover was due to a disaster of some kind, especially if Serviceguard did not start up on the failed node when if rebooted.
Only activate it if you're sure this VG isn't active anywhere else.

for safe testing You can use
vgchange -a r /dev/myvg01

to my eyes, this sounds like a vg left over from testing, so I'd first do a
strings /etc/lvmtab to see which disk devices it ought to use and check their availability using lssf or ioscan -fnCdisk.
