[cisco-voip] Cisco IM & Presence 11 5.1 SU2 corrupt install with 2nd server

Fri Aug 25 10:30:45 EDT 2017

Ordinarily I'd say work with TAC however, on install issues if the problem isn't a glaringly obvious config issue TAC is probably going to need you to pull logs and packet captures so they can read them. Sometimes, its much easier to do that yourself; or at the very least have the logs and captures ready before opening the TAC case.

First off; I'd try to dump the install logs to a file using the serial port method and try to decipher the errors. Here are some instructions on how to capture logs on a fresh install: https://supportforums.cisco.com/t5/collaboration-voice-and-video/dumping-cucm-fresh-install-logs-virtualization/ta-p/3148966

Beyond that, here are a couple of things to try/verify ....

1.) CUCM PUB

  *
Make sure you are not committing one of the original sins: From CLI, utils diagnose test
     *   NTP at Stratum 3 or better (and no MS Windows based NTP servers ... very strange things may/usually happen if you violate this rule)
     *   DNS fully resolvable in both directions for all cluster nodes
  *   Verify you don't have any unnoticed replication issues: From CLI, utils dbreplication runtimestate
  *   Delete the secondary IMP server reference in System>Server
     *   Restart CM services on all CUCM cluster nodes or just reboot each CUCM server (maintenance window as needed)
     *   Reboot the IMP primary
     *   Re add the IMP secondary reference back in under System server (make sure you add it as an IMP node and not a voice/video node ... sounds obvious but you'd be surprised)
  *   During the next installation attempt of this server, do a packet capture from CUCM Pub's and IMP Primary's CLI, during the whole time of the IMP secondary server installation attempt. Instructions for packet captures are here: https://supportforums.cisco.com/t5/collaboration-voice-and-video/packet-capture-on-cucm-appliance-model/ta-p/3118507

2.) Virtual Host

  *
Verify the virtual host server is using NTP (preferably the same reference clock that CUCM pub is using)
  *
Verify there are in-fact enough reserved compute resources for this node, on this virtual host (no over subscription of resources)
  *   Disable LRO on the virtual host .... I know I know, supposedly not an issue with RedHat/UCOS after ESXi 4 ... but it can still cause issues. Admittedly, you'd likely have issues with other UC servers if LRO was the problem BUT - when chasing phantoms, you have to look in all the dark corners

3.) Networking

  *
Do you have other UC servers on the network you're trying to put this IMP node on?
     *
If not, I'd revivify everything on this network; latency, window size, any restrictive port ACLs, any firewall that might be doing packet filtering/inspection... etc
     *
If you do, verify any ACLs in the path that are inclusive only to hosts and not the network (making sure any new UC IP addresses are allowed) .. etc

Yeah I’m not sure what the issue is but I recall having to on one occasion install and recover the config to a clean install before installing the second, for some reason it just refused to add a second server to the cluster on a preconfig. I think there might’ve been a bug in the old OVAs that impact the publisher. I have no factual proof for that though, and I can’t remember if there was a cisco stance on the problem.

Thanks Ben!

That was it. Didn’t occur to me that there might be a problem in the ova template. Perhaps the secondary has to replicate during installation and there wasn’t enough disk space? The BE6K comes with version 1.2 of the ova template, but there is a 1.4 version on CCO. The installation hasn’t finished yet, but it’s much further along than it been before.

Yes, It’s a BE6k. Haven’t thought to re-download the template, worth a try.

Just curious, is your first server from the BE6/7000 Preconfigures? I remember having a few major issues in the past adding servers to a cluster from one of the preconfigured templates on 10.5 and 11.0, wondering if it might be that same issue.

I’ve tried repeatedly to install our second IM server, and it always fails with a corrupt file during post-install. I re-downloaded the ISO and recreated the bootable ISO, so I don’t believe it’s a ISO issue. Anyone see this?
