I have some VI-Perl scripts which track VMs using the bios.uuid, and I am looking into adding SRM into the mix. Can anyone give me some more info on how VMs are tracked in the primary and recovery sites?
As I understand it, SRM has two vCenter servers, one for the primary one for the recovery site.
When I look at the VMs in the vSphere client, do they look the same in each location? Are the names, or anything else, different?
At a lower level, how do the VMs look? Will their VMX's have same or different bios.uuid and vc.uuid in primary and recovery sites?
They do look the same - same name same VMX files - however in the recovery site there is not much you can do as the replicated LUN has not been made active - in terms of the UUID I believe that will change since that is based on the ESX host but I am not sure -
If you find this or any other answer useful please consider awarding points by marking the answer correct or helpful
Nate, when you protect a VM, a "placeholder VM" is created at the DR location. This creates a new vmx file.
When you failover, that VMX file is unregistered and the same one you were using at the protected site, that was replicated over, is added to inventory, hence, it would then assume that same uuid.
Does that help?
