Issue in Volume Group

shameemsoft — Sun, 23 Jan 2011 05:18:14 GMT

Hi,

we have metro cluster servers(Server A & Server B) with HP UNIX 11iv3 update 6.

Server A is down due to some issue & ignite image is not working.

We tried to restore Server B ignite image. it was successful. But volume group information is not correct as we have restored Server B image.

Due to this, volume group(except vg00) is not activated.

can we restore /etc/lvmconf directory from backup or any other way to resolve this issue?

Kindly advise on this.

Regards
Shameem

First of all check if these VGs were cluster
aware or not ,if yes they are they may not be activated normally until you use vgchange -c n
& then vgchange -a y.

In any case please check if these VGs are imported or not ,do they exist in /etc/lvmtab
or are shown by vgscan -v -p ( preview)
if yes then create a new lvmtab file.

Do check if the device files for the VGs are
backed up or not.

Thanks

Hi,

activiates VG in cluster mode

# vgchange -c n

# vgchange -a y

check if respective VGs are activited and able to display

# vgdisplay VG_name

if not you can run

# mv /etc/lvmtab /etc/lvmtab.date

# vgscan -v -p ( if it is success then run)

# vgscan -v

You will have a new lvmtab file in your system in /etc

Or probably you can restore /etc/lvmconf/vg.map files and import it
