Hi itrc55

Clarify us what required.

DO you need to create new VG or need to increase the VG size.

guess so that You requirement is increasing the VG size.

1.Allocate the required disk from storage.

2.Find the cxtydz no

3.pvcreate /dev/rdsk/diskno ( if persistent device file)

4.vgextend /dev/vgname

5.lvextend -L size in mb [lvname] [vgname]

5.vgdisplay -v vgname

6.fsadm -F vxfs -b size mountpoint

to use fsadm online JFS feature must be installed.

to check swlist | grep -i online

if not you have to unmount the file system

umount the file system and do extendfs

if the system is in cluster ,,,, do a vgexport and do vgimport in the fail over server.

regards

Madhu

Consider to use the system management homepage (smh) to create and manage your volume groups.

Since this is VxVM you should try smh, otherwise you need to work with

# vxdiskadm.
