Our requirement is unused disk (PV) from the VG: vguat1 should be moved and added to the VG: vgoradata, since the space is less in VG: vgoradata.
I could see that /dev/dsk/c3t4d0 is not used. Enclosed is the file for your reference. Please revert for any more details.
Server: HP-UX B.11.23 U ia64
Could any one help me to I accomplish this task?
Thanks in advance.
Regards,
V.P

Re: VG creation
If c3t4d0 is not used, you could detach it with vgreduce vguat1 /dev/dsk/c3t4d0.
After that you could vgextend vgoradata /dev/dsk/c3t4d0 with it.

Re: VG creation
Since '/dev/dsk/c3t4d0' is unused, 'vgreduce' it from the volume group, 'vguat1'. To add it to the 'vgoradata' volume group, you would use 'vgextend'.
The problem that you have, however, is that the maximum number of physical extents for any physical volume in 'vgoradata' is 1618 (Max PE per PV). The physical volume you want to add can hold 4374 extents.
Thus, if you merely 'vgextend' c3t4d0 into the 'vgoradata' volume group, you are only going to gain 1618 extents of usable space.
You should 'vgmodify' the 'vgoradata' volume group to increase the maximum number of physical extents that can be allocated from any of the physical volumes in the volume group.
See the manpages for 'vgreduce', 'vgextend' and 'vgmodify' for more information.

Re: VG creation
check your Max_PE_per_PV settings in the vol grps. If the disk is truly 140 Gb, then you'd be wasting a lot of disk space by putting it in vgoradata.

The manpages include some good examples. I urge you to read them.

SolutionYou will have to modify the number of Max_Pe_per_PV setting in vgoradata. You can use vgmodify, the man pages will help. You are using 11.23 so you may have to download a patch to install 'vgmodify', PHCO_35524. here's a link to a pdf og vgmodify.
