VIO Backing Disk LPAR how to find which one ?

hello Folks,

my vio:

now on my LPAR

# lscfg -vl hdisk3
hdisk3 U9117.MMA.6534BE4-V3-C9-T1-L810000000000 Virtual SCSI Disk Drive


But I want to know if Hdisk0 is aix1rootlvm(vtscsi4) or aix1rootvg(vtscsi0) ?

How could I know it?

I found the solution;

From HMC

Check the SCSI virtual adapters for the VIO and Client

VIO Virtual SCSI Adapter Number = 11
Client SCSI Adapter Number = 2

VIO Virtual SCSI Adapter Number = 13
Client SCSI Adapter Number = 9

So on the client side
# lscfg -vl hdisk0
hdisk0 U9117.MMA.6534BE4-V3-C2-T1-L810000000000 Virtual SCSI Disk Drive
# lscfg -vl hdisk3
hdisk3 U9117.MMA.6534BE4-V3-C9-T1-L810000000000 Virtual SCSI Disk Drive

on VIO Server
vhost0 U9117.MMA.6534BE4-V2-C11 0x00000003

VTD vtscsi0
