Hi im trying to create a SQL failover cluster. We already have two server 2012 file servers with their raid arrays clustered but no ISCSI so I installed the target feature in server 2012.
None of the guides ive found online for this cover setting up the storage all just detail running setup.exe. So im wondering what kind of storage setup is needed. ie one large vhd that's added to the target or multiple small ones.
Ive tried adding 4 vhds to the target and running iscsi auto discover on all the potential cluster nodes which adds the 4 disks to all servers but they can only be brought online on the first node and after successfully creating the cluster it runs however after adding sql to the second node the service fails to start because the disk cant be found.
Ive tried adding 4 vhds to 4 targets each accessible to only one server but this causes only one disk to come online in failover cluster manager.
Can anyone suggest the correct way to configure disks for a failover cluster ?
