GRE and Old CM Hostname

Jump to solution

Hello:

I'm looking for help with this recent issue I've uncovered. I recently migrated our Cell Manager from domainA to domainB with a new hostname and IP address. The process is not straightforward so I managed to get it working by following http://www.v-strange.de/index.php/dataprotector/18-migration/12-move-cell-manager-to-different-host-and-ip, http://blog.ifost.org.au/2014/09/changing-hostname-of-data-protector.html, and http://www.ifost.org.au/dataprotector/documents/dp-change-uid.pdf.

Everything seems to be running OK, except I cannot register the 'Advanced GRE Web Plug-in' to my vCenter 5.5 (Windows) and vCenter 6.5 (Appliance). The error returned is:

Following error(s) occurred during Register of Advanced GRE Web Plug-in

oldhostname-fqdn:5555

The GRE configuration must be referncing the old Cell Manager hostname but I do not know where. Looking for any insight as to where I can find this config and change it.

Many thanks!

I posted the same question in the Practioners Forum. This section doesn't have nearly as much activity.

I had an issue where the uninstall/reinstall via the Manager GUI wasn't updating the GRE version and had to go into the vCenter MOB page, unregister it and do an uninstall from Program and Features of the Data Protector.  

The thread here gives some file locations, albeit 2012 so locations could be changed, but could be a good start:

Funny that the linked thread is one started by myself! Unfortunately in this case, those steps do not apply since the vCenter I have has never had GRE registered to it. The trouble I'm having is before it gets registered; it's still referencing the old Cell Manager host name.
