I'm helping a customer that is having issues setting up a Windows 2012 R2 cluster\SQL Server 2014 FCI. The cluster validation tests indicate that No disks were found on which to perform cluster validation .
Their storage set up includes a MSAS 2040 array with SAS. They have 2 adapters that appear to be mapped to the same storage pool. In disk management there are two disks (besides the local) listed both the same size and with the same partitions. They did not configure MPIO.
I have not seen this configuration ( SAS) before. Will configuring MPIO likely fix the issue. Or is something more going on. Is SAS compatible with shared disk?
thanks
Peter
