Procedure
1
Select an array in the Logical View. Then, select either the Array >> Add Free Capacity (Drives) pull-down menu option, or Add Free Capacity (Drives) from the right-mouse pop-up menu.

Result: The Add Free Capacity (Drives) dialog is displayed. The dialog presents the RAID level and the existing drive capacities of the selected array. A table is also displayed that contains information about the unassigned drives that are available for selection. For Fibre Channel drives, the ID is the actual ID rather than the preferred ID.

Important:

  • If you are adding SCSI drives, select drives that are on different channels to minimize the impact of a channel failure.
  • Whenever possible, select drives that have a capacity equal to the current drive capacities in the array.
