UCCX 8.0 - 1st node crashed

Question

Hi,
We have a 2-server UCCX 8.0 cluster running on UCS servers. Recently, when moving the publisher (1st node) to a new UCS server, we accidently deleted some files of the Virtual machine. (there are 2 folders in the datastore, named UCCX1 and UCCX1_1; my colleague deleted the UCCX1_1 folder as he thought it was not neccessary). After that, the ESXi kept asking for UCCX1_1\UCCX1_1.vmx file when we trying to boot the server. We had to re-add the server (browse to the vmx file in the datastore, and Add to Inventory); the server could boot up now, but I think we lost all the data (we cannot access to the Application web page).
Now we still have UCCX 2 running, could we force the 1st server to update its database to sync with the UCCX 2? If YES, how to do that?
If NO, what should we do? Re-install everything or is there a better way to recover the cluster?
Thanks,
hoanghiep

Hi Hoanghiep,
You can not make the UCCX 8.x series second node as the first node, this was supported only on Windows platform (i.e. UCCX 7.x and earlier releases).
If you have taken a valid DRS backup, than yes reinstall the UCCX 8.x first node (with the same details as before like hostnema, ip address, DNS....etc) and than restore this backup.

Restoring only the Publisher Node in an HA Setup (with Rebuild)
In a high availability (HA) setup , if there is a hard-drive failure or any other critical hardware or
Software failure which needs rebuild of the Publisher ( first ) node, then follow the below procedure to
recover the publisher node to the last backed up state of the publisher. Run the below procedure if you
have a valid backup taken before the failure of the node.
Procedure
Step 1 Perform a fresh installation of the same version of Cisco Unified Contact Center Express (using the same
administrator credentials, network configuration and security password used earlier) on the node prior
to restoring it. 
For more information on installing Cisco Unified Contact Center Express, see the Installing Cisco
Unified Contact Center Express available here:
http://www.cisco.com/en/US/products/sw/custcosw/ps1846/prod_installation_guides_list.html
Step 2 Navigate to Cisco Unified Contact Center Administration, select Disaster Recovery System from the
Navigation drop-down list box in the upper-right corner of the Cisco Unified Contact Center Express
Administration window, and click Go.
The Disaster Recovery System Logon window displays.
Step 3 Log in to the Disaster Recovery System by using the same Platform Administrator username and
password that you use to log in to Cisco Unified Operating System Administration.
Step 4 Configure the backup device. For more information, see Managing Backup Devices, page 7.
Step 5 Navigate to Restore > Restore Wizard. The Restore Wizard Step 1 window displays.
Step 6 In the Select Backup Device area, choose the backup device from which to restore.
Step 7 Click Next. The Restore Wizard Step 2 window displays.
Step 8 Choose the backup file that you want to restore.
Note The backup filename indicates the date and time that the system created the backup file.
Step 9 Click Next. The Restore Wizard Step 3 window displays.
Step 10 Select the feature UCCX.
Step 11 Click Next. The Restore Wizard Step 4 window displays,
Step 12 When you get prompted to choose the nodes to restore, choose only the first node (the publisher).
CautionDo not select the second (subscriber) node in this condition as this will result in failure of the restore attempt.
Step 13 To start restoring the data, click Restore.
Note During the restore process, do not perform any tasks with Cisco Unified Contact Center Express
Administration or User Options.
Restoring the first node may take up to several hours based on the size of database that is being restored.
Depending on the size of your database that you choose to restore, the system can require one hour or
more to restore.
Note Based on the requirements, you have the option to either retrieve the existing publisher node data
from the DRS backup to be available on all the nodes in the cluster or retrieve the more recent
data (if available) from the subscriber node to be available in the cluster.
Step 14 Run the following CLI command from the Subscriber node after the restore process is successful (restore
status indicates 100 per cent) to inititate restoring the Publisher node only (with rebuild).
utils uccx setuppubrestore
Step 15 Run the following CLI command on the target node; that is if you want to retrieve the publisher node’s
data, then run this command on the subscriber node, but if you want to retrieve the subscriber node’s data
(which is more up-to-date), then run this command on the publisher node.
utils uccx database forcedatasync
Warning In any case, you must execute this command on either of the nodes after restoring the publisher node.
Step 16 Restart both the nodes and run the following CLI command on the Publisher node to set up replication.
utils uccx dbreplication reset
For more information on restarting, see the Cisco Unified Communications Operating System
Administration Guide available here:
http://www.cisco.com/en/US/products/sw/custcosw/ps1846/prod_maintenance_guides_list.html.
CautionIf you have done some configuration or hardware changes while performing fresh installation in Step 1 that might impact the License MAC, then rehost your license again using the license rehosting mechanism before running the CLI command “utils uccx dbreplication reset”. For more information on the licensing rehosting mechanism, see the Installing Cisco Unified Contact Center Express available here:
http://www.cisco.com/en/US/products/sw/custcosw/ps1846/prod_installation_guides_list.html
Step 17 Your data gets restored on the publisher node. To view the status of the restore, see the “Viewing the
Restore Status” section on page 19.
Hope this helps.
