Re: How to increase the size of a existing volume group
to extend size for vg you can either use vgextend command at command prompt or
you can use SAM > Disk & file system > Volume Group > Click on Action > create or extend specify unused disk there will extend your current vg.
before that you need to verify in your server should have one or more free disk extend vg.
if you dont have space you can add new HDD and add that HDD in existing vg.
if you can tell me your requirement we can guide you accordingly.

Re: How to increase the size of a existing volume group
As indicated in previous answers, the best way is to execute following commands:
1. Find a free disk from following commands:
# strings /etc/lvmtab <---- Dont use disks present in this o/p as they are already a part of some VGs
# ioscan -fnC disk <---- look for CLAIMED disks and disks other than that present in /etc/lvmtab
Adding the disk:
2. # pvcreate /dev/rdsk/cxtxdx
3. # vgextend vg_name /dev/dsk/cxtxdx
Checking:
# vgdisplay -v vg_name <---- look for new disk name and Free PE (it will be increased)
OR
# strings /etc/lvmtab <--- you wills see a new disk here
Hope this helps !!

Re: How to increase the size of a existing volume group
Check, the free space in vg00:
# vgdisplay vg00
Look for ├в PE Size (Mbytes)├в and ├в Free PE├в and multiply them.
The result is the free space in MB in vg00.
Extend the logical volume:
# lvextend ├в L
Extend the filesystem
# fsadm -F vxfs -b
NOTE: You need to add M directly to the lv_size MB value.

Re: How to increase the size of a existing volume group
steps are:-----
(1)ioscan -fnC disk-- check the path of new disk by comparing with /etc/strings.
(2)check the current free space of vg by PE size*free PE in vgdisplay -v /dev/vgname o/p
(3)pvcreate /dev/rdsk/cxtxdx new path of pv
or pvcreate -f /dev/rdsk/cxtxdx (forcefully)
(4)vgextend /dev/vgname /dev/dsk/cxtxdx
(5) check the size of free PE as mention in (2)
for hpux 11iv3 you can use #vgmodimy to extend the vg.
