DESCRIPTION
Using
unallocated disk
space
You can add more storage space to a volume if there is still some space unallocated on the
same disk group.
Adding disks You can add one or more disks to a JBOD, RAID 1 or RAID 5.
The hard disk you want to add must have capacity equal to or greater than the smallest disk in
the volume or disk group.
Replacing with
larger disks
You can replace smaller disks in a RAID 1, RAID 5, or RAID 6 with larger disks.
Replace disks one-by-one.
Replace the smallest disk in the volume or disk group first.
After replacing a disk, you must use the Internal Storage screen’s Manage link to repair the
volume.
Wait for the repair process to complete before you replace another disk.
