Dear Mentors
we configured Microsoft fail over cluster service for two nodes to
install an SAP High-Availability for production environment.
Operating system : windows server 2012 R2 standard
Storage : SAS disk with mapped iSCSI LUN as Raw LANS
we have configured disks in RAID level 10
SAP recommends Cluster validation report should not contain any warning
and errors according to installation guide
You must validate your failover cluster configuration by running the
command test-cluster in a PowerShell
The Failover Cluster Validation Report must not show any warnings and
errors.
But we are getting following warnings after running test-cluster report.

Test Disk 0 does not support SCSI-3 Persistent Reservations commands
needed by clustered storage pools that use the Storage Spaces
subsystem.
Some storage devices require specific firmware versions or settings to
function properly with failover clusters. Contact your storage
administrator or storage vendor for help with configuring the storage
to function properly with failover clusters that use Storage Spaces.
