     NOTE1: If you try to configured a RAID ARRAY and you may receive an misleading
            error message 'DEVICE IS CURRENTLY UNAVAILABLE'. There is no problem
            with the device. The explanation is because you MUST be 'root'.
    
     NOTE2: If you attach a 2nd backplane that was previously attached on another
            SCSI adapter, don't forget to delete the resource name sesX
            otherwise, the disks will not be seen. The resource sesX  will not
            re-appear after a cfgmgr or a reboot but the disk will be seen as
            candidate for RAID.
     
    
      Displaying the FRU of a disk in an array is impossible with lscfg.
      You can display some disk VPD information as follow:
    
          - smit devices
           - Disk Array
            - IBM PCI SCSI Disk Array
             - PCI SCSI Disk Array Manager
              - Change/Show PCI SCSI RAID Drive Status
               - Display Vital Product Data
                  ( select scraid0 )
                     Then move cursor to desired item and press Enter.

                     29 Channel 2 ID 8 ONLINE hdisk2
                     2A Channel 2 ID 8 ONLINE hdisk2
    
                      The next panel displays the desired item again.
                      - Press Enter again
                        and then it finally displays something like:
