We have an Infrastructure with one VC4 and two clusters with 2x 3.5 Hosts and 2x 4.0 Hosts. Both cluster have connection to a netapp FAS 250. After we upgrade the VC the 3.5 Hosts can´t see the disk of the second LUN and the 4.0 Hosts see the path to both LUNs but don´t show any disk. VC says that state of path from the 4.0 Hosts are failed. After many hours reading documentation and whitepapers from Netapp and VMware i don´t find any solution for our Problem. On 3.5 Hosts i can connect the disk on the second LUN if i have a single VC session on the host but not from a VC Session.
What can we do?
