  Logon with the Spectrum Protect server instance userid and
  run the following commands from a shell :
  
  db2 connect to tsmdb1
  db2 set schema tsmdb1
  db2 "select volid,volname,maxocc,estcap from as_volume_status"
  
  If select output shows any volume with estcap=0, you are
  affected by this problem.
  
  Additional Keywords:

  Versions Affected:
  IBM Spectrum Protect server V7.1 and 8.1 on all platforms.
  

Local fix

• Run the following Spectrum Protect server administrative
  command :
    q vol stg=<pool-name> status=empty
  Replace <pool-name> with the name of the storage pool being
  converted with the CONVERT STGPOOL command.
  For each empty volume, run the following Spectrum Protect server
  administrative command to remove the volume :
    delete volume <volume-name>
  Run the CONVERT STGPOOL command after the empty volumes have
  been removed.
