Chapter 11 Administering and maintaining the K2 Storage System
Managing redundancy on a K2 Storage System
If you have a redundant K2 Storage System (Level 2R or Level 3R), use the
procedures in this section to control the primary/redundant roles of the K2 Media
Servers. Procedures are as follows:
• “Identifying current primary/backup K2 Media Servers” on page 330
• “Triggering an intentional failover” on page 332
Identifying current primary/backup K2 Media Servers
Before attempting any configuration or service work on a redundant K2 Media
Server, you must be know if the server is the current primary server or the current
backup server for the media file system and database. While most configuration and
service work can be accomplished on a backup server without affecting the operation
of the Storage System, if you attempt configuration or service work on the operating
primary server, it will likely result in record/play failures and/or a loss of media.
To identify the current primary/backup K2 Media Server, use one or more of the
methods described in the following procedures:
Identifying primary/backup from NetCentral
While monitoring the K2 Media Server in NetCentral, do the following:
1. In the NetCentral tree view, select the K2 Media Server.
2. Click the Facility view control button
3. Open the Roles subsystem
4. Click the Media Database Server link.
The Media Database Server dialog box opens and reports the Failover Mode as
either Primary or Backup.
Identifying primary/backup from the K2 System Configuration application
1. In the tree view, select the name of the K2 Storage System, which is the top node
of the storage system tree.
2. Click the Server Control Panel button. The Server Control Panel opens.
