2. Enter information about the LSU.
StorageServer Select the storage server that will contain the new LSU.
AvailableCapacity (Recommended for best performance) Select this option to add an LSU that
uses the available capacity on the system.
You cannot add an available capacity LSU to a storage server that already
contains an LSU. Also, if you add an available capacity LSU to a storage
server, you cannot add additional LSUs to that same storage server.
Note:After you add an LSU that uses the AvailableCapacity option, you
cannot change the LSU to use the SpecificCapacity option. Instead, you
must delete the LSU, then add a new LSU and choose the Specific
Capacity option (see Deleting an LSU on page 261).
SpecificCapacity Select this option to specify the physical capacity of the LSU, and then enter
the following information.
l LSUName - Enter the name of the LSU.
l PhysicalCapacity - Enter the physical capacity of the LSU (1 to 1048576
GB).
Note:Quantum recommends setting LSUs to maximum size (1048576
GB) because spanning them on a backup is not possible.
