Cluster validation report having warnings

[former_member214873]

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.

Persistent Reservation Registration key 0x1000100b2 for Test Disk 1

reservation holder node orenprdB.oren.in was not removed by the call to

REGISTER using RESERVATION KEY 0x1000100b2 and SERVICE ACTION

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.

subsystem.

Hi,

Dear Peter

I ask about Microsoft cluster validation report contain warning Storage Spaces Persistent Reservation,  can I continue for SAP installation.

Because SAP Installation guide mentioned : 

You must validate your fail over cluster configuration by running the command test-cluster in a PowerShell

The Failover Cluster Validation Report must not show any warnings and errors.

I Had confusion whether to go  further  (even though we are not using cluster pool storage spaces in windows server 2012 R2)

Please find reference links we can safely ignore the warning, if your not using  Persistent Reservation Storage Spaces
