Making external mainframe volumes usable
To use external mainframe volumes with a storage system, usually you must use External Storage
to perform external volume mapping, and then use the Format command of Virtual LVI to format
the volumes. However, formatting the external mainframe volumes in this way may take a lot of
time.
If you want to make the external mainframe volumes usable more quickly, you can use an alternate
method:
• “Registering external mainframe volumes” (page 41)
• “Overwriting control blocks in specific external volumes” (page 42)
Registering external mainframe volumes
Using this procedure, you can make the external mainframe volumes usable more quickly.
When the external volume is disconnected, you cannot register the external volume.
