We have a similar setup:
1. ONTAP 9.1 P8
2. We have multiple arrays i.e. 8020's, 8040's, AFF, etc.
3. VMware vCenter 6.0 Update 3(e)
4. Virtual Storage Console 6.2.1P1D2 (Plan in the works to upgrade to 7.0)
5. SnapCenter 4.0 (just recently installed to replace SMVI)
We are stuck with the following error logged in the newly installed SnapCenter in the logs:
ERROR SnapManagerWeb PID=[3388] TID=[223] Failed to find host (X.X.X.X). Please check the host is up and running or check the firewall settings. No such host is known
When we attempt to create a resource group for one of our sites (remote, 8020), we get an error at one (1) of our 3 sites: "Some entities are not SnapCenter compatible." while the other sites (remote, 8040, AFF) work fine...
When reviewing the logs in SnapCenter, the following error is logged: "Failed to get the storage system for host resource"
