RMC cannot find host 192.169.119.131. We are cerating task "action": "Attach Snapshot Sets" and it reports error ""Host 192.169.119.131 could not be found.".

 

 

Fix:

Customer needs to import esx host on the 3par using its IP address.

For DP/RMC Integration, it is a requirement to add ESX on 3PAR using its IP address. When we backup VM, we save metadata which contain destinations ESX for restore, and on the part of attaching snapshot, it is the IP that is being used, which is why you need to add ESX IP on the 3PAR.

It is a configuration requirement. If you need to do DP/RMC integration, ensure you have added the ESX IP on 3PAR.
