This document describes what to do when a Unity Connection Media Convergence Server (MCS) Version 78xx server drive fails or there is another problem with the Redundant Array of Independent Disks (RAID). The aim of this document is to be a central location for customers to find resources to understand and address RAID failure and repair for Unity Connection.

Background Information

If you encounter RAID failure, look in the "Replacing Disks in a RAID" section of the Unity Connection release notes.


Replace Disks in a RAID

Cisco Unity Connection documentation supports the replacement of a defective disk in a RAID with a blank disk in order to repair the RAID. The replacement of disks in a RAID for any other reason is not supported.

Caution: Do not replace a disk in a RAID with a disk that contains data, even if the replacement disk was originally a disk in the same RAID in the same server.

Unity Connection documentation does not include any information on how to replace disks in a RAID array. However, because Unity Connection and Cisco Unified Communications Manager use mostly the same servers, you can use the procedures in the Performing Failed RAID Disk Replacement section of the Cisco Unified Communications Manager System Issues chapter of the applicable Troubleshooting Guide for Cisco Unified Communications Manager.

Troubleshoot Guide for RAID

As noted in the Release Notes, there will not be any more information documented regarding RAID in the Unity Connection documentation. The Communications Manager documenation will be referenced since the platforms are the same between Unity Connection and Communication Manager.

The documentation can be found here:

These articles describe how to troubleshoot based on the model server that is affected.
