This is a disk exerciser utility for CSCti52867 and only applies to server models: MCS-7816-I4, MCS-7825-I4 & MCS-7828-I4.

If the common or root partition is currently in "Read-Only", before installing this cop file, the server must first be successfully recovered utilizing the following workaround:

1.      Reboot the server via CLI if possible.  Otherwise power-cycle the server by holding down the power button for 5 seconds or more.

2.      Boot from a CUCM recovery disk and selection option “f” to perform a file system check.  If it finds errors, then a reinstall and restore from backup may be the only way to recover completely.


 If the workaround is not successful, then this install could fail.

After installing this cop file, the firmware of the Western Digital hard drive should be upgraded to version 3B06.  If the utility need to run again, it may be installed multiple times.
