CUCM Cluster after reinstall!!

Hi experts!

We have a CUCM Cluster with Publisher A and Subscriber B, ccm 5.1.3.

In the Publisher, the hard disk have crashed and I needed REINSTALL.

Now, the Publisher is fine and I have a important question. Could I  plug the Subscriber in the network and the cluster will work´s fine, with the database replication or I mandatorily need to reinstall the subscriber too?

To reinstall the subscriber will be bad, because I dont have the but install CD in the same version of the Subscriber, and I would need reinstall the Publisher again, together the Subscriber and upgrade both nodes....

Thanks!!

HI Marcelo,

You need to build the Publisher first with 5.1.2 bootable DVDs and then, build the subscriber with same version.

then, upgrade both servers to 5.1(3g) in cluster and then, restore backup of 5.1(3g) version on PUB.

You could also apply patch upgrade during the install, so boot from 5.1.2 and when asked if want to upgrade to a patch upgrade select yes and use the 5.1.3 ISO/media/sftp.

If I recall correctly with version 5 you need to resintall the sub if you reinstalled pub, this should be documented in the proper release notes.

Hi Marcelo,

In addition to what Mr. Chris has said, what is the exact CUCM version u are using.

I was refering to release notes of Call manager 5.1(3a) , where in the bug related to your case

CSCsj90196 Bug Details

Change DRS process to not require sub rebuild/restore
Symptom:
CM5.x and 6.x disaster recovery currently requires subscriber reinstall. CM3.x and 4.x did not require subscriber reinstall after BARS restore.

Conditions:
Perform DRS restore on CM cluster.


Workaround:
After DRS restore on publisher reinstall each subscriber in the cluster.

I hope u might have performed DR after Publisher was rebuild.
