Well need some help here. 

VCS running X7.2

1.  VCS was configured for primary cluster.

2.  Had Database Failure indication in the clustering section. 

3.  Deleted fields in clustering page saved and restarted VCS

4. After restart had resources = zero and verified Optionkeys installed and looked norm.  No alarms or errors.


5. Decided to reinstall firmware X.7.2.0 .... 

6. Same result... resources = zero


Any ideas please.

Hi Chet,


i will suggest you to open the TAC case. They can try to remove the cluster-db and see if it helps.

Hi,


Are you saying that you have removed the primary VCS from the cluster? You should not remove the primary VCS from the cluster, even when you have a data base failure. You should first set another VCS in the cluster to be the master, then you can remove the faulty VCS from the cluster and then you ca try to re-add it again to the cluster (it normally requires a factory reset in the VCS before re-adding).


Can you confirm if you really have simply removed the primary VCS from the cluster without following Cisco documentation?


Regards

Please, take a look at the session “VCS database failure: Please contact your Cisco support

representative” of this guide:


Starting on page 59 -

http://www.cisco.com/en/US/docs/telepresence/infrastructure/vcs/config_guide/Cisco_VCS_Cluster_Creation_and_Maintenance_Deployment_Guide_X7-2.pdf


That describes exactly your problem and how to fix that.


In this case, I strongly recommend you to open a TAC request.


I hope this help.

I opened a TAC: 627219079.


I am going to work the first issue. That is The error  "Failed - This Peer either has a different list of peers or it has a different software version installed."  and I have  in the Cluster database status section   STATUS = FAILED on both VCS's.


I upgraded both of them from X6.0 to X7.2.0.

Hi,


I recommend you to remove the cluster, restart the VCSs and leave in standalone mode.


After that, you have to create again the cluster.


If you have a configuration backup you can do a restore.


Regards.

I did that already and no change. 

Would it be good to just reinstall the firmware ??

Hi Chet,


I don't think this is going to resolve your issue. According to the documentation I posted above, the best way is to do the following:


  • Set anohter VCS as the cluster master
  • Factory reset the faulty VCS
  • Add that VCS back to the cluster again


Of course, that is just a summary, there are too many steps involved, obviously, and the documentation describes all the steps required. As those tasks have a high risk level, I strongly suggest to follow the documentation step-by-step and the instructions provided by TAC support. I really don't suggest you to try to resolve the problem by yourself without assistance from TAC.


I hope this help.

All three of them have the same indication.

I did change the master and tried it again but no luck.


What is strange is the fact the error says either there is a different list of peers or software version different.


I re-installed the firmware on all three with the exact same firmware file.  I also have all peers IP's in the same Peer on each VCS but the darn things day

Database status "FAILED"

Last Sync "FAILD" except the master which is "SUCCEED". 


Sheesh CISCO must be real friends with Microsoft ........ I like Polycom Network devices.


Yep I am frustrated.

Chet,


Did you try to factory reset the faulty VCS or you just simply reinstall the software? You can try to factory reset, upgrade and then add to the cluster again. If the data base status for the master peer is good, so you can add the faulty peers to the cluster again from zero.


The doc explains how to remove the VCS from the cluster in the session "VCS database failure: Please contact your Cisco support". Did you try that procedure?


Regards

Hi Chet,


the reason for "the error says either there is a different list of peers or software version different" points towards the faulty database on the peer.


this is possible with cluster-db correuption on the secondary.


Have you opened the TAC case? what is the SR number?

Yes I did. They asked me to do a factorydefault reset to see if that clears it.

Hi Alok,


Have you the VCSs in VMware or they are appliances?


There is a way, in vmware to change the image to load at the beginning of the boot proccess. You can change the boot load to load the image2 instead of the image1.


I have two VCSc in lab enviroment and I had the same issue. With this change was resolved the issue.


Note that you lost all configuration of your VCS (factory default) and I had to configure again (restore).


Regards.

Hi Romero,


Chet is facing this issue not me .


np. just to clarify you have two images on appliance box also. and you can select the other image using "selectsw" command boot the box through it.


however in this case the box actually falls to the previous image which box has came with in case if you have performed any upgrades and you might not have any config. And when you reload the software it actually reload the sw on your default image only. So in your case you might have recovered this way but chet has tried the reload and it didn't fixed the issue.


Chet,


give me sometime i will reach home and give you some steps to try out.

I will be standing by.  No changes made today other than remove cluster information from the page and save and restart.

Hi Chet,


since you have removed all the config for cluster you need to rebuilt it again. I hope you are using TMS PE right?


- make a note of all option keys 

- login to VCS secondary peer using root and run the command "factory-reset -i", this will ask you to keep the option keys, ip-address, etc.

- Once this is done you will still retain the ip-address and option keys etc.

- configure the DNS, NTP etc on the secondary peer, make sure the software version is still same on both master and peer needs to be added.check the option keys as well. they should still present.

- come to Master login as admin, put the server in maintenance mode using command "xconfig system unit maintenance mode: On"

- navigate to master web page go to clustering configure the fqdn for cluster, shared key and master ip-address(only master ip-address) and click save. and restart the master server.

- once master is up, go to secondary peer, put the secondary server in maintenance using the above command.

- come to master go to clustering configuration add the secondary peer ip and click save

- come back to secondary peer, configure the clustering information on secondary peer. put cluster fqdn, shared key, master ip, peer ip and click save.

- go back to CLI interface of secondary peer in admin mode, run the command "xcommand defaultvalueset level: 2"

- run the command "xcommand defaultlinks add"

- restart the secondary peer.

- wait for 2-4 min and then check the clustering page on both the server. status should be "succeeded" and "last synch result should also be success.

- if the replication is proper the master will replicate all the  search rules, transforms, account etc to secondary peer.

- if you master is using TMS PE the secondary should automatically switch to PE if not, we can manually do it.


Most of the scenario i have resolved issue using this procedure. There is another way of doing it without doing factory-reset however in your case since master is working fine i think the above procedure should be ok.

Hi Alok,


OK.


Yes, I know that you can change the image in appliance too. But in my case the VCS are on vmware.


My issue was resolved with this method.
