Moving your PDDE /Storage from existing LUN (full) to New created LUN

Problem Description :   I run out of    PDDE   Disk capacity, The backups on  the PureDisk Volume  were  fails with status code 129.

   I did the following  : -

 moved the   existing  PureDisk Volume  /Storage to Newly created LUN (high Disk capacity)
 

• PDDE  /Storage is mount on /dev/dsk/c1t500A09818617DCC6d0s7 ( 30 GB LUN)
• df -h /Storage/ shows

Filesystem             size   used  avail capacity  Mounted on
/dev/dsk/c1t500A09818617DCC6d0s7
                        30G    26G   2.9G    91%    /Storage

When 91% of   /Storage touches  HWM, Backup operation starts  failing  with Status 129 : -
1/19/2009 09:36:31 - requesting resource PDDESTU
11/19/2009 09:36:31 - requesting resource qedisk5.NBU_CLIENT.MAXJOBS.dbautown1

• umount /Storage/
• mkdir /nonstd/
• mount   /dev/dsk/c1t500A09818617DCC6d0s7 /nonstd/

•  Mount the new 80 GB LUN to /Stoarge       : -  mount   /dev/dsk/c1t500A09818617DCC6d1s6   /Storage/
• df -h

                    dev/dsk/c1t500A09818617DCC6d1s6
                        79G    64M    78G     1%    /Storage ( new  80 GB )

                        30G    26G   2.9G    91%    /nonstd ( Exitsing 30 GB  )

• mv -f   /nonstd/*   /Storage/
• NetBackup Deduplication Manager start
• NetBackup Deduplication Engine start
• Refresh the Status of Disk POOL

When you restart the  JOB failed during 129 status, The backups operation will start on    PureDisk Volume with new capacity  (80GB in this case)

****************Please note that I tried this solution as a  experiment  case **************
