changing hostname for uc cluster

Hello,

I've gone through the steps to change hostname on my unity connection cluster, everything seems to have completed fine with Pub retaining the primary status, however one thing bugs me when I get output of show network status, I get the following:

tcp        0      0 produc02:51485            produc02:unityconnect02_ccm7_1_5_30000_1 TIME_WAIT  
tcp        0      0 produc02:51486            produc02:unityconnect02_ccm7_1_5_30000_1 ESTABLISHED
tcp        0      0 produc02:51487            produc02:unityconnect02_ccm7_1_5_30000_1 ESTABLISHED
tcp        0      0 produc02:51490            produc02:unityconnect02_ccm7_1_5_30000_1 TIME_WAIT  
tcp        0      0 produc02:51496            produc02:unityconnect02_ccm7_1_5_30000_1 TIME_WAIT  
tcp        0      0 produc02:51499            produc02:unityconnect02_ccm7_1_5_30000_1 ESTABLISHED
tcp        0      0 localhost:1502              localhost:33053             ESTABLISHED
tcp        0      0 localhost:1502              localhost:33052             ESTABLISHED
tcp        0      0 produc02:unityconnect02_ccm7_1_5_30000_1 produc02:51487            ESTABLISHED
tcp        0      0 produc02:unityconnect02_ccm7_1_5_30000_1 produc02:51486            ESTABLISHED
tcp        0      0 localhost:1502              localhost:33049             ESTABLISHED
tcp        0      0 localhost:1502              localhost:33051             ESTABLISHED
tcp        0      0 localhost:1502              localhost:33063             ESTABLISHED

oldname was unityconnect02, and new name is produc02. Am not sure what is "unityconnect02_ccm7_1_5_30000_1" which still has this old hostname. Does it matter or needs to be changed, if yes, where do I get to change this to reflect the new name rather than old one.

Re: changing hostname for uc cluster

I believe you are OK looking at the output.  However, my first question is does the host table look the same on both servers?  Are you running DNS or not?

So, your output actually shows this:  produc02:unityconnect02_ccm7_1_5_30000_1 produc02:51487

So, you have the new name followed by a reference to the old name which is followed by the full version that was loaded at the time followed by the new host name.

Is this an 8.0 cluster?

Re: changing hostname for uc cluster

No this isn't an 8.0 cluster, just like the name shows its a 7.1(5) cluster.

I am not using DNS, just using IP addresses(now that you've asked, I wanted to ask whether DNS is a must/recommended? or can I just not use it and be good to go). Currently we have DNS on our network, but on UC servers it is not configured aka not dependent on it.

For this entry, I'm showing the same on both servers, pub and sub. I can re-run the db sync but wonder if that would clear out this entry cause the first time it didn't which is why I'm seeing it in the output.

Re: changing hostname for uc cluster

Making the Unity dependent on DNS is not advisable as you would be adding another point of possible failure in your network.

Re: changing hostname for uc cluster

Hi Thomas, thanks for reiterating this and that was the reason behind going with IP addresses. I appreciate your input.

Still looking answers on the other query I posted.

Re: changing hostname for uc cluster

you've probably gone through this - http://www.cisco.com/en/US/docs/voice_ip_comm/connection/7x/upgrade/guide/7xcucrug060.html

did u follow the steps as per the document? or where there any steps you ommited?

Re: changing hostname for uc cluster

also verify replication via RTMT and/or CU Reporting. we'll first try to get an idea whether this is affecting your servers in any way

Re: changing hostname for uc cluster

I've gone through those steps and all of them were followed.

Replication is fine, and is verified through rtmt and also cli.

Re: changing hostname for uc cluster

Any suggestion on this one?

Here is one clue I can provide.

When you go to UC Administration page, and click on Message Storage>Mailbox Sotres

Click on the mail database link

Against the server field, it shows the older name, even though everything has been changed to the new one.

PLUS this name is all greyed out so one cannot tweak it in this field, it just displays and is greyed out.

How do we correct this to the new hostname of the server? (OR) does it matter if we really have to?

I like things consistent which is why this is bugging me.

thanks for your help.
