today I have a customer that wanted to upgrade from CUCM 9.1.2 to 10.5 – which sounds pretty easy… think again, so this is a BE6K deployment where CUCM instance was configured with the recommended OVA from CCO.
When starting the upgrade I found that the upgrade didn’t wanted to proceed as expected. and I was getting the following error:
Installation of UCSInstall_UCOS_10.5.1.10000-7.sgn.iso failed
An error has occured but no messages are available. This can happen when another administrator is working on the system at the same time and triggers an error.
So just curiosity I was looking for the error but no clue, so I decided to save the logs and found the following:
08/28/2014 23:09:13 refresh_upgrade|File:/common/download/10.5.1.10000-7/refresh_upgrade:641, Function: validate_free_space(), Not enough space on partition to proceed|
after looking for possible solutions I found a COP file called Free space, this COP file helps you clear all the information from the Common folder and the inactive partition where you might have an old version installed from previous upgrades (be careful if you use this you wont be able to go back to that version…IMO who would want to go back to that version in the first place??).
So that didn’t fix my issue… why would it? – Then I found another tool called:
UCM VM Dynamic Disk Size Reallocation COP File
Which its name explains it all, use the Readme file if you want to know how to use it. to save you the trip to the ReadMe file here are the steps that you need to take:
1. (UCM 9.1 and earlier only) Install the “ciscocm.vmware-disk-size-reallocation-1.0.cop.sgn” COP file.
2. Shutdown guest VM
3. Open VMware Infrastructure (VI) Client and connect to VirtualCenter or the ESX host.
4. Right-click the virtual machine.
5. Click Edit Settings.
6. Select Virtual Disk.
7. Increase the size of the disk.
8. Power on guest VM.
The system will restart twice after you first turn it on (Very scary if you ask me!), because it need to recognize the new space and expand the system.
After this the upgrade proceeded very nicely.
I hope this information helps someone having the same issues!
