[cisco-voip] No access to Publisher

Thu Jan 3 10:53:57 EST 2013

Hi Terry,

Thanks for the info.  Cisco are recommending I rebuild the server as if it were a fresh install on CUCM, the Publisher will then push the configuration to the Subscriber once added to the cluster again.

Thanks

Cos

If you have tried the recovery disk already then I think you may not have much options left. You would probably try rebuilding the server with the procedure TAC is recommending. 

Since you are restoring on subscriber only, even if you restore from 6th December backup, dbreplication should take care for the rest. Is TAC recommending this way? How bad is your dbreplication, its just bad on this server, rest two have good status?? 

If not already given, ask TAC to give you a precise action plan and follow that closely. That may be your best bet.

Good luck with that, keep us posted !!

Cheers Terry,

We tried the recovery disk yesterday, it stated that it was successful and then we were getting the same errors.  I sent the errors over to TAC and they came back with rebuilding from backup, but the earliest backup we have is Dec 6th.

Hi Costas,

Not a problem. Few things i would suggest.

1) First of all try if you can recover the servers using recovery disk. Once you can access the servers and verify dbreplication (repair, reboot if you nned to) is correct then take a good backup and move ahead with rebuild. Now if you question, why to rebuild if everything is good - because it will again go into read only mode or start having dbreplication issues or file system errors in a week or two.

2) Regards to your question of backup restore, if possible best approach would be to restore from backup. Thats how Cisco recommends, in the doc, if you go to replacing a subscriber section. That works fine.

3) And for your server accesibilty and errors, I would suggest you to run a recovery disk and recover your server first. It would require a reboot.

4) In the end, if you are not able to recover your server by all means, then consult with TAC and rebuild the server and let dbreplication do the work, if you dont have a recent good backup. But again I would say if you must do this way get full consultation from TAC first. 

When I ran into this first time, TAC recommended to first recover the server to normal to minimize any risk. Everything went fine with that approach.

Hi Terry,

Thanks for the info, appreciate it.  I was going to rebuild then let replication do its thing, do you suggest restoring with a backup?  Currently replication is not working, I was going to rebuild the subscriber then do a reboot on all servers probably on Monday to sort out replication.  The reason for this is because I have top raise a change request, I have only joined this company and found the server down when I downloaded RTMT.  Also, just to let you know, I cannot access the faulty sub, i get to the CLI enter username and password then get lots of error messages and it hangs.  Cisco recommended the rebuild.

To add further to below mail:

Once you record all information. Take a  backup of your system.
Shut down the server and rebuild the new server with information at your hand. 
In the end restore back up data to this node.

Hi Costas,

While rebuiding servers most critical thing is you need to record info from old servers and enter the same information in new servers.

Please refer to the below document and read carefully. It has all the pre-checklists  and post check lists. The pre-checklist has all the information you need to gather before you start the rebuild, which is very critical.

http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/install/8_5_1/cluster/clstr851.html 

I have done this few times, and in one case eventually I had to rebuild the whole cluster. Whats the hardware? I had done this on MCS servers, but process will be almost same even if you have UCS, where you can simply create a new VM. But you need to gather and record all information before you start the rebuild. When you rebuild, all the information on server being rebuilt should be exactly same as per original server.

I will try to quickly summarize the info you would need to collect before you start, but still i will highly encourage you to go through the above link, its best resource. Below information you will be asked when you are rebuilding the server:

1) Get your security password for the cluster (very important, reqd for dbreplication, you have to be 200% sure, if you are not sure, go ahead and first change it on all servers - i think you can do from recovery disk, if you dont know the security pwd, if i correctly remember, and you need to restart all servers after changing)

2) Record your administrator login/pwd

3) Record application login/pwd

4) run and record output from cli - show network eth0
It will give you ip address, subnet, default gateway, duplex, dns etc all network related info

5)  run and record output from cli - utils ntp status. Will give all ntp servers

6) run and record output command show status from CLI, will show hostname, license mac etc.

7) Record all device information etc from RTMT device summary
prior and match the same post rebuilt.

8) After rebuilt make sure dbreplication is good, may take abt 15-20 mins to syncronize

Hope that helps and let us know if you have any other query.

Terry

Hi All,

I have been informed by Cisco that I have to rebuild my subscriber (version 8.5), are there any good Cisco docs out there on rebuilds?

Hi,

Thanks for getting back to me.  I tried restarting Tomcat on the pub and I can access it for a while then I can't.  Tomcat service on the Sub, i cannot restart yet as I cannot access the server.  DO you think these problems are due to the Sub being down?  I think this server has been down for a few days.

Hi All,

I was wondering whether anyone has come across this before.  I have just started at a new company and they have a CUCM cluster running 8.5.1, they have one pub and two subs.  I downloaded RTMT and noticed that one of the subs was not accessible, I can ping the IP address, but cannot access it via SSH or URL, someone should be going to the site today to re-boot.  The day after, I could no longer access the Publisher, this server I can access via SSH, but cannot access via URL or RMTM, I stopped and started the Tomcat service and it came back for a while, but after a while i cannot access again. 

Any Ideas. 

Regards

Costas
