0516-622 Cannot write Logical Volume Control Block

Question:

Env:
  AIX 3.2.5
  
Desc:
  Customer just added a new OEM drive to the system.  The 
  customer then added this disk to the rootvg and migrated hd1
  to this drive.  The customer then tried to increase /home by
  20mb and got this error message:

    0516-622 Cannot write Logical Volume Control Block
  
  df did show that the filesystem did increase

Action:

   getlvcb -At hd1
     0    0    0

     Looks like the logical volume control block is
     messed up

  I made sure this was a filesystem and not a raw lv before
  I had him run this command.  NOTE: RUNNING THIS COMMAND ON
  A RAW LOGICAL VOLUME CAN RESULT IN DATA CORRUPTION OR DATA
  LOSS.
  
  putlvcb -N hd1
  chfs -a size=+1 /home
    This worked with out a problem
  getlvcb -At hd1
    looks correct now

Next Action:
  Closing with customer approval
