Introduction
This document provides a sample configuration to repair dead disk drives in the Opal platform on Cisco 7300
Series Content Engines (CE−7300s) or Cisco 4650 Content Distribution Managers (CDM−4650s).
Prerequisites
Requirements
There are no specific requirements for this document.
Components Used
The information in this document is based on these software and hardware versions:
• CDM−4650 that runs Application and Content Networking System (ACNS) 4.0 or later
• CDM−4650 with a Redundant Array of Inexpensive Disks (RAID) controller
• CE−7320 and CE−7320−DC that run ACNS 4.0 or later
The information in this document was created from the devices in a specific lab environment. All of the
devices used in this document started with a cleared (default) configuration. If your network is live, make sure
that you understand the potential impact of any command.
Conventions
For more information on document conventions, refer to the Cisco Technical Tips Conventions.
Configure

Step−by−Step Instructions
CDM−4650
When one physical disk goes bad, the system is still operable. You do not lose any data if you repair the disk
before a second disk goes bad.
Perform these steps to repair the disk:
1. Find out which disk drive is bad and record the disk ID.
2. Issue the reload command−line interface (CLI) command to reboot the box.
3. Turn off the box.
4. Replace the bad disk with a new blank disk that is of the same type and the same or larger capacity
size.
5. Turn on the box, and log in.
6. Issue the disk raid−array repair disk XX command.
Note: For XX , use the ID of the dead drive.
The disk replacement process takes a very long time. Expect a degradation of performance during the
disk replacement.
Refer to Cisco ACNS Software, Release 4.1 for additional command information.
CE−7320 and CE−7320−DC
If one disk goes bad, you lose content and/or software. Disk00 is important because disk00 contains the
software. If the bad disk is not disk00, you can replace the bad disk.
Perform these steps to repair the disk:
1. Find out which disk drive is bad and record the disk ID.
2. Power down the CE.
3. Replace the disk, and restart.
4. Issue the disk add disk XX command to create a new file system on the disk.
The CE disks are Just a Bunch Of Disks (JBOD). Therefore, you do not need or want RAID. The dynamic
content fills in automatically. Since storage of the software is on disk00, you need to reinstall software on
disk00 after you replace that drive with a blank disk. Issue the copy ftp install command to perform the
reinstallation. For this process, you must have the .bin image file on an FTP server that is accessible by the
CE. You also need to perform the process from the CE console. Issue the EXEC mode CLI.
Note: You lose all content, which includes your configuration and logs, on the disk00.
