ONLINE CAPACITY EXPANSION

Add Capacity
You can add a physical drive to an existing array to expand capacity only under the following
conditions:

configured, Add Capacity feature is unavailable.)

Please reboot OS, after Add Capacity is completed. If it does not reboot, an error event
may be periodically registered into the event log of OS.
NOTE: Available RAID level for the capacity added array
depends on the number of physical disks configuring the
array.
Two physical drives: RAID 0 or 1
Three or more physical drives: RAID 0 or 5
New drive(s) can be added to the SCSI bus or subsystem
(e.g., disk rack).
IMPORTANT: It is recommended to make backup copy of
partition on logical drive before adding capacity.
After Add Capacity completion should reboot OS.
When not rebooting The following error events may be
periodically registered into the Event Log(Application Log)
of OS.
