argument which I use for the VM Guest vgmodify?

[Eli Daniel]

Hi Torsten
I dont understand vgmodify in the VM host and VM guest?

I need to know how to increase or add a new disk to VM guest?
example:
Vm host
vgapp1 assigned LV disk to Vm Guest.

Vm host:
i need add 1 disk to vgapp1 and expand LV disk Vm guest.

Vm hosts:
vgextend /dev/vgapp1 /dev/dsk/c1t4d0
lvextend -L xxx /dev/vgapp1/lvapp1

Vm Guest:
lvextend -L xxx /dev/vg1/lv1

This is correct??

If you extend the lvol on the host, you need to use vgmodify on the guest to make it aware of the increased virtual disk. Then you can use lvextend there.
