Online Vgextend

[HP UX Admin]

Hi,

Is it possible to extend the VG online.Already the VG has filesystems mounted in the system.

Pls consider both the cluster and standalone scenreo.

You can change a VG online only. Just do the "vgextend". In case of cluster, you need to transfer the configuration to the other nodes.

Hi Torsten,

Thanks for your valuable reply.

I understood the same,
Pls see the following procedure,and pls correct me if i am wrong.

In standalone sytem,

pvcreate /dev/rdsk/c7t9d0

vgextend vg02 /dev/dsk/c7t9d0 >>>>>> No need to unmount the filesystems of vg02

In cluster environment,

pvcreate /dev/rdsk/c7t9d0

vgextend vg02 /dev/dsk/c7t9d0

vgexport -vps -m /tmp/vg02.map vg02
copy the mapfile to the system 'B'.

In a system 'B'

vgexport vg02
vgimport -v -s -m /tmp/vg02.map vg02

Hi,

the above procedure is correct. Just a note to the clustered version: for doing the vgexport the vg should be deactivated, and thus, it should also be umounted on the passive node.
