mapped volume automatically becomes Normal. However, the volume formatting processing
is not executed automatically. If you need to format the mapped volume, format the volume
using the VLL function.
For the volume formatting operation procedure, see the HP StorageWorks XP24000/XP20000
Virtual LVI/LUN (VLL) and Volume Shredder User Guide.
Go to step 4.
3. If you set the emulation type for the mainframe system when you map the volume, the status
of the mapped volume becomes Blockade. Format the volume using the VLL function. Or if

the external storage system side, perform the Write to Control Blocks operation using the VLL
function to restore the volume.
For the volume formatting operation and Write to Control Blocks operation procedures, see
the HP StorageWorks XP24000/XP20000 Virtual LVI/LUN (VLL) and Volume Shredder User
