Re: reclaim disk space to eva4000

Take note of the physical volumes on the unused VG's by:

# vgexport -p -v vg_name

Then export the VG by:

# vgexport vg_name
If you're going to use it on the same system, simply force recreation of VG structure by:
pvcreate -f {noted physical volumes on first step}

Then extend the other VG to the physical volumes noted above. Take note of the size of the re-claimed disks and MAX PE per PV value of VG you want to use them in.

If you want to use it on a different system, then you have to go to EVA and unpresent the Virtual disk and present it to system that needs the disks.

Dear Pando

if u want to present the disk again
u can do from eva, by presenting vdisk in to the hostname. Once disk is presented u can create physical volume and then volume group ok

thanks and regards
