10-4-1 Allocating Storage (Adding Volume Paths)
System administrators and storage administrators can allocate storage. Guests, local system administrators,
local storage administrators, and local guests cannot allocate storage.
When you allocate storage, you assign one or more access paths (specifying ports and LUNs) to LDEV(s), and
you can optionally secure the new LUN(s) to host WWN(s). You can allocate LDEVs that are unallocated or
already allocated.
You cannot assign paths to LDEVs in the following cases:
•
For StorageWorks XP1024/XP128
A path is already set from the same LDEV with the same security.
•
For storage subsystems other than the above
A path is already set from the desired LDEV.
To allocate storage:
1.
Log in to Device Manager as a system administrator or storage administrator.
2.
Select and expand the Subsystems object in the navigation frame, open the physical view for the desired
storage subsystem, and then open the LDEV Information panel for the array group that contains the
LDEV(s) that want to allocate (see section
10-2-4
).
NOTE:
You can also allocate storage by starting from the All Storage/My Storage object (see section
8-4
). Select any storage subsystem under All Storage or My Storage, and then select the Open-
Allocated group or the Open-Unallocated group that contains an LDEV.
3.
Select the desired LDEV, and then select ALLOCATE to open the Add Storage wizard.
