Binding Hot Spare drives
You can bind disks as hot spare drives. Hot spare drives are on standby and are used in the event of a drive failure in a RANK. If a drive fails, the RAID Controller automatically selects a hot spare drive to use in place of the failed drive. This prevents the system from operating in a degraded state.
If the drives you want to designate as hot spares are bound as part of a RANK, you must unbind the drives first, then bind them as hot spares. To function as a Hot Spare, the drive must be at least as fast and have at least as much capacity as the failed drive it replaces.
- In Storage Utility, right-click the Unbound node for a controller, then select Bind in the context menu. (Peer controllers that share the same set of disks are automatically selected as a pair.) The Binding dialog box opens showing all unbound disks for the controller listed in the Available Disk list.
- Select Hot Spare using the BIND TYPE drop-down box.
-
In the Available Disks box, select the disk(s) to be used as hot
spares, then click the add (arrow) button to add them to the Selected Disks
list.
Note: As an aid in identifying a disk module’s physical location, select it in the Selected Disks list, then click Identify Disks. This causes the disk drive LED to flash.
- Click OK to close the Binding… dialog box and begin the binding process. The Progress Report dialog box opens, showing the status of the binding process.
- Upon 100% completion, click Close in Progress Report window.
- Restart the K2 Media Server.
