Objective
Moving existing LUs from Shared Storage Pool (SSP) to New SSP cluster or same SSP cluster.
Environment
VIO Server 2.x, 3.x, 4.x
Steps
Steps:
======
1) Select All Systems ( Left Top System )
2) Under "All Systems", select your system by selecting the selection ion on top left of system.
3) Select Action, then view system partitons
4) This should already show you the VIO Server partitons.

6) Enter the Partition Name, under Create New Parttion.
7) Select Partition Type, AIX etc
8) Select OK
9) The view will now show the new lpar
10) Check lsmap from the VIO console using, "lsmap -all". Below showing for one VIO. Same for other VIO.
where there will be no VTD or Backing Device assigned yet.
