Extending vg00

[Sarah Mokwana]

On HP-UX 11.00, how do you extend vg00 not the filesystem.

[Vincenzo Restuccia · Accepted solution]

#vgextend /dev/vg00 /dev/dsk/cxtyd0

Hi,
if you want to increase a Volume Group you will need to add some volumes (i.e. new disks):
vgextend /dev/vg00 /dev/dsk/c8t2d0

good luck,
Thierry.

Hi Sarah.
Before you extend the VG (vgextend vg00 /dev/dsk/cxtxdx), you might need to execute "pvcreate /dev/rdsk/cxtxdx" to create the physical volume for use in LVM.
good luck

before adding to the vg00 .

hi,
if u r extending to another disk say cxdxtx
then u need to initialize the disk for use with LVM


# pvcreate -f /dev/rdsk/cxtxdx

# vgextend vg00 /dev/dsk/cxtxdx

Hi,
You need first to create physical volumes ( pvcreate) and then extinding the volume group ( vgextend ).

Hi Sarah,
All answers seems to me wonderful,but if you 'll use pvcreate then it depends on which VG,if VG is root then you must use option -B,if not then just only pvcreate for example

pvcreate -B /dev/rdsk/c1t6d0
vgextend /dev/vg00 /dev/dsk/c1t6d0

goodluck
