Chapter 11 Administering and maintaining the K2 Storage System
Expanding the media file system by capacity
NOTE: This procedure should only be attempted under the supervision of qualified
Grass Valley support personnel. Contact your Grass Valley representative for
assistance.
If you need to increase the storage capacity of your K2 Storage System, you can do
so by adding one or more Expansion Chassis, up to the maximum number of chassis
allowed for your level of storage.
When expanding by capacity, you must add enough storage to support the entire
bandwidth load of the system. For example, if the current system requires six LUNs
to support its bandwidth specification, then you must add another six LUNs to expand
the system’s storage capacity.
When you add an Expansion Chassis to increase storage capacity, use the following
procedure:
1. Install and cable the Expansion Chassis.
2. Bind the LUNs in the Expansions Chassis using Background Bind.
3. When binding is complete, put the K2 Storage System in an offline state 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.
4. Restart all K2 Media Servers. Do not use the standard startup processes here. Just
start up the server(s) and wait until the Windows desktop appears. Especially do
not open Server Control Panel or start Failover Monitor.
5. On the K2 Media Server with the role of primary media file system/database
server, save a copy of the following files to a different location:
D:\snfs\config\default.cfg
D:\snfs\config\cvlabels
6. In Storage Utility, select Tools | Expand File System By Capacity .
7. A message box reports progress. When a message reports success, the process is
complete.
8. Restart the K2 Storage System.
