Chapter 7 Disk Array Configuration Setting
IV-23
With Pool rebuilding: Allows expanding the capacity of the pool without any restriction on the
number of the logical disks, in a relatively longer time.
Specify Expansion Time: Allows specifying the duration of time to expand the all physical disks only
when you specified “With Pool Rebuilding”. Although specifying 0 expands
the capacity in the shortest time, select an appropriate time taking account of
the load to the host I/O. The time specified in the field is just a target, thus it is
not assured to take the specified time.
Selection PD for Expansion
Unused PDs: Lists disks still unused.
Pool PDs: List of disks that will compose the pool after expansion
Number of Adding PDs: Number of physical disks to be added to the pool
[Add] button: Select unused physical disks to use for the pool in the “Unused PD” list, then click this
button to add them to the pool.
[Delete] button: Select any physical disks to be removed from the pool in the “to Pool” list, then click this
button. The selected physical disks are restored to the list of unused physical disks.
* It is not allowed to select any physical disks already put in the other pools.
Clicking the [OK] button displays a confirmation to ask whether you want to expand the capacity of the pool.
If the physical disks selected are insufficient for the expansion, either of the [25218] or [25227] message box is
displayed as follows:
