HP StorageWorks XP Remote Web Console Software - Manual (Page 237)

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 step 3. 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.
2. From the Customized Volume pane, right-click the LDEV folder at the top of the tree, and select
Write to Control Blocks.
3. In the Write to Control Blocks pane, select the desired external LU group from the Candidate ExG
list, and click Add. The selected external LU group moves to the Target ExG list.
NOTE:
• You can select one or more external LU groups.
• To remove external LU groups from the Target ExG list, select the external LU groups
from the list, and click Delete. The external LU groups move to the Candidate ExG list.
