Delete Volume Group and Create Volume Group in MC/Service Guard

Gd Day Forum,

I would like to delete a volume group vg06 from a cluster node pair NodePrimary and NodeSecondary and recycle vg06 with smaller number of harddisks.

Correct me if I am wrong,

Query: I need to vgexport /dev/vg06 on both the cluster nodes first?

Then I will perform the following:-

@NodePrimary
1) mkdir /dev/vg06
2) chmod 755 /dev/vg06
3) mknod /dev/vg06/group c 64 0x060000
vgcreate -p 64 -e 10000 -s 4 /dev/vg06 /dev/dsk/c3t0d1
4) vgexport -p -v -s -m /tmp/vg06.map vg06
5) ftp the /tmp/vg06.map to NodeSecondary

@NodeSecondary
1) mkdir /dev/vg06
2) chmod 755 /dev/vg06
3) mknod /dev/vg06/group c 64 0x060000
4) vgimport -v -s -m /tmp/vg06.map vg06

Just wondering did I miss out any commands?

Regards/cliff

your plan looks fine to me, and yes you will need to vgexport the vg on both nodes before recreating it

Hi,

Please don't forget to run
vgchange -c y /dev/vg06
on one of the mchines when the cluster is running.
