In this post I would explain this issue I encountered while deploying Data Recovery vApp.
...Yes, I know Data Protection Suite is the current backup solution and Data Recovery is now old anyway our customer just needed it so I was told to install it.
After VM deployment I went to vSphere Client -> Solutions and Applications -> VMware Data Recovery selected Data Recovery appliance and clicked connect.
After a while it returned me this error:
Could not connect to the Data Recover service on the appliance. If the problem persists, please restart or redeploy the Data Recovery appliance.
Well, after logging in into Data Recovery console I figured out my error:
vCenter is in 192.168.0.0 network while VMs and consequently Data Recovery appliance runs in 10.0.0.0 network so obviously Data Recovery was unable to reach vCenter.
To solve this issue was enough to add to Data Recovery appliance an IP in 192.168.0.X class.
By default Data Recovery appliance is deployed by an OVF which attaches two NICs to this VM. In my case just one of these (eth0) was used so I had eth1 connected to VM but with no IP assigned. For me it was sufficient to edit eth1 config file; if you have eth1 already configured you need to add another network adapter to Data Recovery virtual appliance and edit the corresponding ifcfg-ethX file under /etc/sysconfig/network-scripts/
service network restart
Then back to vSphere Client I was able to connect to VMware Data Recovery appliance and schedule backup jobs.
