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?
