Allow the allocation of additional physical extents to a physical volume:
pvchange -x y /dev/dsk/c0t0d0

Re: extend Virtual Disk on HPUX
That's correct!
Although the OS can see new new disk's size, you still can not extend the Logical Volume.
With EVA, if you want to extend a VG, there are two ways:
1. Create more new Vdisk, then extend it to the VA.
2. Resize the Vdisk.
But in both case, the OS can not automatic extend when you extend the LV.
In this case, you have re-create the LV.
Then you can use the new size (20GB).
You have to backup all data and after re-create the LV, just restore.
In another way, if you don't want to re-create the LV, just create one more Vdisk with 10GB then add to the VG, then you can extend the current LV to the new disk.
Hope this helps,
Cong,

Re: extend Virtual Disk on HPUX
But the increase is only possible if the volume group is offline.
Do "vgchange -a n" and "vgmodify" to get the new extents into the LVM configuration.
My 2 cents,
Armin

Re: extend Virtual Disk on HPUX
Your HP-UX system seems to run with a pretty old patchlevel. You should urgently consider installing a current patchelevel!
