CSCuc63312 : Not enough disk space in the common partition for upgrade

CSCuc63312 : Not enough disk space in the common partition for upgrade

If you are upgrading your CUCM from 9.x version to a higher version, you may encounter an issue stating “there is not enough disk space in the common partition to perform the upgrade” which is caused by the bug CSCuc63312.

There are two ways suggested to clear this issue :

Using RTMT (Real Time Monitoring Tool)

We need to reduce the amount of traces on the system by lowering the high and low watermarks in the Cisco Log Partition Monitoring Tool.  The low and high watermark can be adjusted by changing the properties of the LogPartitionLowWaterMarkExceeded and LogPartitionHighWaterMarkExceeded alert respectively.  The default value for the low watermark is 80 and high watermark is 85. Soon after the upgrade, we need to ensure that we restore the value of Low and High watermark to their respective default values.

How to change the values?

  • Login to Real Time Monitoring Tool
  • Enter your Cisco Unified Communications Manager IP Address, User ID and Password
  • Click on Alert Central
  • Right Click on > LogPartitionLowWaterMarkExceeded and click on Set Alert/Properties
  • Click on Next
  • Lower down the threshold value
  • Click on Next
  • Click on Save
  • Right Click on > LogPartitionHighWaterMarkExceeded and click on Set Alert/Properties
  • Click on Next
  • Lower down the threshold value
  • Click on Next
  • Click on Save

Start upgrading your server again and see if  you don’t encounter this error. Once the server is upgraded, restore the threshold values back. If you are still getting this error, you need to use alternate method by installing cop file on the server.

Installing COP files on CUCM Server

  • Download the COP file ciscocm.free_common_space_v1.0.cop.sgn from CCO
  • Install the COP file on the server where you are encountering space error. You need to install the cop file using SFTP Application.
  • Once the COP file is successfully installed, you may proceed with the upgrade.
