Managing redundancy on a K2 SAN

If you have a redundant K2 SAN, 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 402

• “Triggering an intentional failover” on page 404

• “Recovering from a failover” on page 405

Identifying current primary/backup K2 Media Servers

Before attempting any configuration or service work on a redundant K2 Media

Server, you must know if the server is the current primary server or the current backup

server for the media file system and the metadata service. While most configuration

and service work can be accomplished on a backup server without affecting the

operation of the SAN, 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 or Metadata 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 SAN, which is the top node of the

storage system tree.

2. Click the

Server Control Panel button. The Server Control Panel opens.
