7-6-5 Removing Storage from a Group
The system administrator, local system administrator, storage administrator, and local storage administrator
can remove storage (LUNs) from an existing storage group. Guest and local guest users do not have access to
this function.
When you remove storage, you remove the selected LUN(s) from the storage group. During the remove
storage operation, you can choose to keep or delete the LUN(s) (access paths) themselves.
NOTE:
To remove paths from LDEVs, use the unallocate operation (see section
8-5
).
CAUTION:
Before deleting a LUN, make sure that no access is underway from a host. When a LUN is
deleted, all I/Os being executed between a host and that LUN are canceled.
NOTE:
For StorageWorks XP Disk Array: Even if a LUN is deleted, the storage subsystem port or HSD to
which that LUN belongs is not reset.
NOTE:
For StorageWorks XP512/XP48 LUN group: When you remove storage belonging to a LUN group,
you must select all storage in that LUN group. If you wish to remove only a portion of such storage, you must
first remove the desired LUNs from the LUN group, and then remove the storage.
To remove storage (LUNs) from a storage group:
1.
Log in to Device Manager as a system administrator, storage administrator, local system administrator, or
local storage administrator.
2.
You can start the remove storage operation from either the Logical Groups object or the Hosts object in
the navigation frame:
•
From Logical Groups, select the storage group that contains the LUN(s) that you want to delete.
•
From Hosts, select a host that is associated with the storage group that contains the LUN(s) that you
want to delete.
3.
In the information frame, select the LUN(s) to be deleted, and select Remove Storage. If you select an
unremovable LUN, an error is displayed in the pop-up window.
Restrictions on deleting LUNs:
•
For StorageWorks XP12000/XP10000 and XP1024/XP128, you cannot delete the last volume path of
the logical device specified as a copy pair volume.
•
For StorageWorks XP512/XP48, you cannot delete the last volume path of the logical device set as a
command device or the logical device specified as a copy pair volume.
