Loading RAID controller and expansion chassis microcode
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.
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 SAN must be offline.
• All iSCSI clients and K2 clients in the K2 SAN 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 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.
To upgrade microcode, do the following:
1. If upgrading expansion chassis microcode, take the RAID system offline.
2. In Storage Utility, right-click a controller in the tree view, then do one of the
following:
• To load controller microcode select Advanced | Load Controller Microcode
• To load expansion chassis microcode select Advanced | Load Disk Enclosure
Microcode
Redundant controllers that share the same set of disks are automatically selected
and upgraded as a pair.
The Open File dialog box appears.
