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

[Cliff Lim Kok Hwee]

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?

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.
