CUCM Version 14 Backup

[Kashan Memon]

Hi team, 

I am trying to take manual backup for CUCM by SFTP device, i tried WinSCP and SolarWind but i faced a following error (Add failed : Unable to access SFTP server. Please ensure the given path is correct.) 

note: the hard drive for CUCM is FULL, no space at all. 

What should i do?

I would start by clearing out space on the CM. You can do that by running the latest version of the cop file named ciscocm.free_common_space_v1.11.k4.cop.sha512 that can be downloaded from Cisco. Also try freeing up space by removing trace files from your system by these command.

This document can also provide useful info on common things to look at when your file system is full. https://www.cisco.com/c/en/us/support/docs/unified-communications/unified-communications-manager-callmanager/221038-troubleshoot-full-common-partition-in-cu.html

WinSCP is not an SFTP server; it’s a client used to access an SFTP server. WinSCP will not work for backups.

It appears to be a reachability issue. Make sure the CUCM can reach the SFTP server on port 22.

From the CUCM CLI, run the command: utils network connectivity <SFTP server IP> 22. If the CUCM can reach the server, it will show “service accessible.”

Test this and let us know the output of the above command.

To ensure the SFTP server is accessible, you can use WinSCP to connect to the SFTP server and verify its functionality.

unfortunately, CLI is not accessible while the drive is full, I have access for VMware, i tried to increase the space but no luck, can i delete some files from CUCM GUI or VMware to gain back CLI access again?

Increasing the hard disk size alone is not a viable solution. The recommended approach is to deploy a new OVA if you need to expand the hard disk size.

Check if you can perform this task by logging into the console, as it cannot be done directly from VMware. You should be able to clear some trace files using RTMT after downloading them, which could free up some space.

Additionally, use the high and low water mark partition feature in RTMT.
