Increase CUCM Disc Space

Make upgrades easier to perform. It's getting harder and harder to make the necessary free disc space to perform a CUCM upgrade. Isn't it about time Cisco increased the disc size for CUCM? Back in the days of the appliances, we used to have 292GB of disc space (2 x 146GB drives). But when we went virtual, Cisco claimed 110GB was enough. With all the Telepresence firmwares, this is getting very tight.GTG is listed in their documentation. In version 10.x and above, CUCM is already coded to allow the disk increase through vmware settings.

Will it be supported by TAC?There are lots of things I could do to my CUCM (e.g. hack the root account and modify the database as the Informix user) but if TAC catch you doing them, they wash their hands of you.

i think that you can do this through the vcenter console for that VMit applies are the next reload

You've been able to do it for versions before 11.xWhether TAC would support you with a non-standard disc size, however, is another matter...

IN 11.x, CUCM/CUC allows you to increase the disk size through vmware settings. It applies the extra storage to the COMMON partition. I had to do this on my CUC servers.
