5.4.2.2 Deleting a Dedicated Spare
You can delete a dedicated spare drive from an array at any time. ..
To delete a dedicated spare:
1.
From SAM, select
Manage EF2800
>
Disk Array Config
>
Delete
Dedicated Spare
. The Delete Dedicated Spare page displays with
a list of existing arrays and dedicated spares.
2. In the EF2800 Storage Array Overview panel, select the array you
want to delete a spare from.
3. In the Delete Spares panel, select the spare you want to delete.
4.
Click
Delete Spares from This Array
.
The drive is now available for use in an array or as a spare.
5.4.3 Managing Global Spares
Global spares let you have one or more disk drives available for the
reconstruction of redundant arrays (mirrored [RAID 1 and RAID 10]
and parity [RAID 3, RAID 4, RAID 5, and RAID 50]). Once you assign a
drive as a global spare, it is not available for use as an array member or
as a dedicated spare.
If a drive in any redundant array fails, the EF2800 can use a global spare
to reconstruct the array. If a global spare is too small (smaller than an
individual member in an array), the array cannot use it.
5.4.3.1 Adding a Global Spare
You can add up to eight drives as global spares to reconstruct any
critical array on the EF2800. After an array has started using a global
spare, other critical arrays are prevented from using it. For a global
spare to be used, it must be as large as the smallest drive in the array.
To add a global spare:
1. From SAM, select
Manage EF2800
>
Disk Array Config
>
Global
Spare Menu
>
Add Global Spare
. The Add Global Spare page
