This document answers some of the primary questions about disk redundancy on the Cisco Media
Convergence Server (MCS). In addition, the document describes how to get the most out of the redundant
disk technology (Redundant Array of Independent Disks [RAID]) that comes with the MCS.

Cisco recommends that you have basic hardware knowledge.

The information in this document is based on these software and hardware versions:

MCS 7830

• 

MCS 7835

• 

Note: The Cisco CallManager OS images have been created for specific fixed hardware configurations on
specific platforms. If you need to increase the hard disk space or performance, you must take a backup.
Complete these steps:

Upgrade the server platform.

1. 

Reinstall Cisco CallManager.

2. 

Use the Backup and Restore System (BARS) in order to restore.

3. 

You must perform these steps in order to use the same platform/server and increase the hard disk space. For
more information about Cisco CallManager hardware, refer to Cisco 7800 Series Media Convergence Servers
