Adding a Spare Disk
If you create a mirrored or RAID 5 array without
spare disks (RAID 0 arrays cannot have spares), fol-
low these steps to add up to two spare disks later:
1
From the Main menu for the array, select Change
Array Configuration
.
2
Select Add Spare Drives.
3
If prompted to enter the number of spares, type
1
or
2
and press Enter.
4
Press Tab to select the channel with the spare
disk(s). A list of disks on that channel appears to
the right. Select each spare disk by pressing the
↑
and
↓
keys until the disk name is highlighted, and
then pressing Ins or Enter.
5
When you have finished selecting spares, press Esc.
6
When prompted, type
y
to accept the new spare
disks, or
n
to reselect the disks.
You need not reformat the array.
Deleting a Spare Disk
To delete a spare disk from an array, select the Delete
Spare
command from the Configuration menu. If the
array has two spares, first select the spare you want
to delete. Type
y
when the prompt asks you to con-
firm the deletion.
Initializing Arrays
When you create a new array or redefine disks (other
than spares) in an existing array, you are automatically
prompted to initialize the array. You can choose to low-
level format the array or initialize it with zeros. (For a
brief description of both formatting methods, see
page 3.)
If necessary, you can reinitialize an existing array if
the data on the array has become corrupted. To do
this, follow the directions in the AHA-3980/3980W/
3985/3985W User’s Guide.
