We have a VM cluster on Netapp storage, and the version of the hosts and VC were 5.5U1.
The backup jobs worked fine through Direct SAN using Veeam BR 6.5.
Recently, we upgraded VC to 5.5U3 for fix some issues, and then the backup jobs became only run in Network mode.
It showed "Direct SAN connection is not available...."
I searched many documents and forums, but there has no discussing relevant to this.
Is there any suggestion or solution that could help us to troubleshooting or resolve this?
PS. Sorry for my bad English.
