You can expand the size of a virtual disk if there are enough unassigned disks and the virtual disk is Online and Ready.
Note: When you expand a virtual disk, the disk drives that participate in the virtual disk must all be of the same type, either Serial Attached Technology Advancement (SATA) or Fibre Channel (FC).
To expand a virtual disk:
The Array Summary page is displayed
The Volume Summary page is displayed.
The Virtual Disk Summary page is displayed.
The Virtual Disk Details page for that virtual disk is displayed.
The Disk List page for the selected virtual disk is displayed.
The Virtual Disk Details page refreshes itself, and a message confirms the virtual disk expansion.
