Check for adapter if for all the vscsi adapters .
After checking adapters id we can go to
the properties of lpar and see which adapter is provided by which vio ,
(adapter client id “C11” is the identification), After recognizing the vio server
we can go to vio server properties and verify which server adapter connects
with which client scsi adapter .Hence we can decide to which server scsi
adapter the disk needs to be provided
