Binding Hot Spare drives
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.
6. Click OK to close the Bind LUN dialog box and begin the binding process. The
Progress Report dialog box opens, showing the status of the binding process.
7. Close the Progress Report and repeat these steps for other unbound disks.
NOTE: RAID controllers can take several hours to bind a LUN. Make sure you
initiate multiple simultaneous binding processes to reduce the overall time.
8. Upon 100% completion, click Close in Progress Report window.
9. Restart the K2 Media Server.
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 LUN. 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 LUN, 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.
The requirements for this procedure 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 Storage System must be offline.
• All iSCSI clients and K2 Media Clients in the K2 Storage System must be shut
down.
To bind drives as hot spare drives, do the following:
1. In Storage Utility, right-click the Unbound node for a controller, then select Bind
LUNs in the context menu. (Peer controllers that share the same set of disks are
automatically selected as a pair.)
The Binding LUN dialog box opens showing all unbound disks for the controller
listed in the Available Disk list.
2. Select Hot Spare using the LUN 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 LUN… 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.
