Adding a sub to a CUCM 6.0.1 cluster

Unanswered Question
Jan 25th, 2008

My cluster was installed with DVD "" and then upgraded with"UCSInstall_UCOS_6.0.1.2000-4.sgn.iso".

Now I try to add a new sub I can't install because it's not compatible with 1rst node and the "UCSInt...6.0.1-2000-4" is not supported for upgrade during installation.

What can I do ? Switch the 1rst node in olest version, install 2nd sub and then switch back to newest and upgrade 2nd sub ? What about config and calls.

Thanks for help

in your scenario you would need to switch partitions and go back to the old version. install the sub and then upgrade the servers

unfortunately the version which is in the inactive partition is not updated with the new configuration you have made since, so you would go back to that point

Thanks for your answer.

Ok for switching back to the old version on the Pub, then install the 2nd sub, but then You mean I can't switch again to the new version on the Pub and then upgrade the sub ?

You mean if a cluster has been upgraded, you can never add a new sub in the config ?

Does an install DVD exist for CUCM ?

not sure if that would work, if you install the SUB and then go back to the new version you won't have any reference in CUCM or at DB layer for the replication since as far as CUCM know there is no SUB in the newest installation.

you can add SUBs but you need to install it with the same version your PUB is

I think you're right. I compared the DVD content ( the iso content ( there are about 20000 bytes difference of size, I think this is olso a full version why is it not bootable ?

For sharing knowledge, the final solution after a lot(like burn bootable DVD, like using 2000-3 which is the bootable versio of 2000-4),all inefficient, was to simply rename UCSInstall_UCOS_6.0.1.2000-4.sgn.iso into UCSInstall_UCOS_ES_6.0.1.2000-4.sgn.iso, the ES transform it on a patch that can be used during install with (or another one)
