DESCRIPTION
ICON
Resync Speed
When a disk array is resynchronizing, you can select it and click this icon
to set how fast the NSA resynchronizes the disk array. A screen displays.
Select the how fast the NSA should resynchronize the array. The faster
the resynchronization, the slower the performance for users accessing
shares. With resynchronizing at a high priority, users may have limited
access speed to shares until resynchronization finishes.
Add Disk
To add another disk to an existing JBOD, RAID1, or RAID5 array, select
the array and click this icon. You can add a disk to increase an array's
capacity or to use as a hot-spare (standby). When you add a disk to an
existing array, you do not have to re-create shares, access rights and so
on as you would if you created a new array.
Reshape: Make a three disk RAID5 array into a four disk RAID5 array.
Expand JBOD: Add another disk to a JBOD array.
Add Hot-Spare: Add a standby disk. For a RAID1 or RAID5 array, the
capacity of the disk you are adding must be equal to or greater than the
smallest disk in the array.
Remove Hot Spare
To remove the standby drive from a RAID1 or RAID5 array, select the
array and click this icon. After you do this, you can create a single-disk
JBOD array for the disk.
