the Customized Volume pane changed to Format, and all of the volume’s information appears in bold
blue italics.
10.
Click Apply. In the confirmation pane, click OK. The words Format in progress appear next to the

Making external mainframe volumes usable
To use external LUs with the array, you must usually use External Storage XP to perform external LU
mapping, and then use Volume Manager’s Format or Format All command to format the volumes (see
” on page 187). However, when you format external mainframe volumes in this way,
the formatting operation might take a long time.
Use the following procedure to make external mainframe volumes usable more quickly.
CAUTION:
Only storage administrators can perform the following operation. Storage partition
administrators cannot perform this operation.
1.
Zero-format the external mainframe volumes.
NOTE:
The term “zero-formatting” refers to a formatting operation that writes the number 0 (zero)
to the entire disk area. For more information about zero-formatting volumes, see the documentation
for the mainframe system or external array you are using.
2.
Use External Storage XP to map the zero-formatted external LUs and register the volumes in an
external LU group. For more information, see the HP StorageWorks External Storage XP Users Guide.
CAUTION:
Ensure that the external LU group does not include volumes that are not
zero-formatted. If an external LU group includes volumes that are not zero-formatted, the volumes
are blocked when you perform the operation described in
. Therefore, hosts cannot read
from or write to the volumes. If you have not zero-formatted external LUs but you want to make the
external LUs usable with the array, use CVS’s Format or Format All command.
3.
Use Volume Manager to specify the external LU group, and overwrite control blocks in the volumes in
the specified external LU groups. After overwriting finishes, the external LUs are usable with the array.
NOTE:
Control blocks are a type of area in a volume that contains information other than user
data. Information required for managing a volume is recorded in control blocks.
To overwrite control blocks in volumes in an external LU group:
1.
On the upper right of the XP Remote Web Console main pane, select a CU group from the drop-down
list.
