Changing the Segment Size of a Logical Drive

Use the Change Segment Size option to change the on a selected . During this operation, I/O performance is affected, but your data remains available.

Keep these important guidelines in mind before you proceed with changing the segment size:

The operation to change the segment size is slower than other modification operations (for example, changing RAID levels or adding free capacity to an array). This slowness is the result of how the data is reorganized and the temporary internal backup procedures that occur during the operation.

The amount of time that a change segment size operation takes depends on these variables:

If you want this operation to complete faster, you can change the modification priority, although this might decrease system I/O performance. To change the priority, select a logical drive in the array, and select Logical Drive >> Properties .

  1. In the Logical pane, select a logical drive, and select Logical Drive >> Change >> Segment Size .
  2. Select the desired segment size.
  3. Click Yes.

    The segment size modification operation begins. The logical drive icon in the Logical pane shows an Operation in Progress status while the operation is taking place.


    Note:

    To view the progress or change the priority of the modification operation, select a logical drive in the array, and select Logical Drive >> Change >> Modification Priority .
