  If a mistake is made while adding a port, or if an HBA is removed from a server that is defined 
  within the Storwize V7000, use the**rmhostport**command to remove WWPN definitions from

  Before removing the WWPN, ensure that it is the correct WWPN by issuing the**lshost**
  command, as shown in Example 8-35.
