Hi,
We have 4 blades with Windows 2016 x64 server installed on them with all the updates etc.
There are two drives on each blade, the OS and then a data drive. We have created a virtual VHD disk on each of the blades stored on this drive and mapped them with iSCSI initiator so that each server can see each of the drives, (4 servers in total, seeing all 4 drives).
We run the Failover Cluster Validation Wizard and it does all the relevant tests, such as mounting disks, failover over disks, and they all come back successful during the validation.
When we create the cluster, all the drives disappear and when you go into iSCSI initiator all the connections are set to 'Reconnecting...' and you can't bring them back online, we have also tried to add our external drive to the server via iSCSI and it's having none of it. Event viewer says the disks have surprised removed!
When you destroy the cluster and give the servers a reboot, all the iSCSI drives re-appear and show as 'Connected'.
In terms of the networking, there are 4 NICs which are all teamed into one, we've tried it this way as well as having separate NICs such as Management and Production & Even Storage, but with no avail.
The fact it works during the validation wizard is baffling, if anyone has any ideas it'd be greatly appreciated!
