Who's disk is it ??

If you have a no pvid disk, defined in a partition, how do you find which one it is, on the VIO server ?
1) on the aix partition :
# lscfg -l hdiskX
=> hdiskX U8203.xx.... V3-C2-T1-L810000.... Virtual...
Slot
Lun
2) Get the AIX client ID :
# uname -L
3 PartitonName
Partion ID
3) On which Vio server is running the partition :
Log on the HMC :
# lssyscfg -r sys -F name <= gives all the managed system names #lshwres -m PowerName -r virtualio --rsubtype scsi --filter lpar_ids=3
Powersystem on which the partition is running
Partion ID in 2)

=>lpar_name=PartitionName,lpar_id=3,slot_num=2,state=1,is_required=1,adapter_type=client,remote_lpar_id=1,remote_lpar_name=VioServerName,remote_slot_num=12,backing_devices=none
Remote Slot number
4) Log on the Vio Server (padmin)
# lsmap -all
note which adapter (vhostX) is on the slot number 12
# lsmap -vadapter vhostX
=> the disk you are looking for, is the one with the Lun Id 810000 in 1)
