Binding Hot Spare drives
Prerequisites are as follows:
• You must access Storage Utility (via the K2 System Configuration application login) with
permissions equivalent to K2 administrator or higher.
• When you access Storage Utility, the K2 SAN must be offline.
• All iSCSI clients and K2 clients in the K2 SAN must be shut down.
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.
1. 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.
2. Select Hot Spare using the BIND TYPE drop-down box.
3. 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.
4. 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.
5. Upon 100% completion, click Close in Progress Report window.
6. Restart the K2 Media Server.
Loading RAID controller and expansion chassis microcode
You might be instructed in K2 Release Notes to upgrade the RAID Controller microcode and/or
expansion chassis on the RAID chassis. This allows you to take advantage of the RAID enhancements
and benefit from improved reliability.
1. If upgrading expansion chassis microcode, take the RAID system offline.
