Create a Hot-spare Drive
Unused physical hard drives may be designated as hot-spare drives. A hot-spare drive
automatically replaces a physical hard drive in a storage pool when it fails, or a when the
Predictive Failure Analysis (PFA) indicates a physical drive will fail.
The modular server system supports both dedicated and global hot-spare drives. A
dedicated hot-spare drive is assigned to a specific storage pool. If a physical drive fails in
the assigned storage pool, the dedicated hot-spare drive will replace the failed drive as
long as the hot-spare drive is equal to or greater than the size of the failed drive. A global
hot spare can replace any failed drive in any storage pool as long as the global hot-spare
drive size is equal to or greater than the failed drive size. Both dedicated and global hot-
spare drives will revert to being a hot-spare drive once the failed physical drive is
replaced.
Once a hot spare is created, the following information is updated:
•
The information icon for the physical drive changes to the hot spare icon,
•
The Role description on the General Tab for the selected physical drive indicates
whether the physical drive is a dedicated or global spare .
•
If the drive is a dedicated hot-spare drive, it will be listed on the Spares tab for the
assigned Storage Pool.
•
If the drive is a global hot-spare drive, it will be listed on the Spares tab under all
Storage Pools.
To create a hot-spare drive, follow these steps:
1. Click Storage in the top menu or click System > Storage in the left navigation panel to
open the Storage screen.
2. Select an available or unused physical hard drive from the system graphic.
This is a drive that is currently not used in a storage pool.
3. From the "Drive <#>" Action menu, select Make Hot Spare.
4. Configure the hot spare as either a global hot spare (available to all storage pools) or a
dedicated hot-spare drive (assigned to a specific storage pool) and click Apply.
Once the hot spare has been created, a successful action dialog will be displayed and
the information icon will change to the hot spare icon,
