Making External Mainframe Volumes Usable

The following procedure enables you to make external mainframe volumes usable.

1. Zero-format external mainframe volumes. For information on how to zero-format volumes, see

the documentation for the mainframe system or the external storage system that you are using.

2. Use XP External Storage to map zero-formatted external volumes and register the volumes in

an external volume group. For detailed instructions on how to do this, see the HP

XP24000/XP20000 External Storage Software User Guide.

3. Use Virtual LVI to specify the external volume group, and then overwrite control blocks in the

volumes in the specified external volume groups.

• To overwrite control blocks in a volume, see “Overwriting Control Blocks in Specific

External Volumes” (page 79).

• To overwrite control blocks in all volumes in the disk groups or parity groups, see

“Overwriting Control Blocks in All External Volumes in Disk Groups or Parity Groups”

(page 79).

After overwriting finishes, the external volumes will be usable with the storage system.

CAUTION: Only storage administrators can perform this overwriting operation. Storage

partition administrators cannot perform this operation.

While this overwriting operation is in progress, you can perform the following operations only

when the SVP system option 503 is set:

• Volume to Space

• Install CV
