Windows 2008 cluster disks show "Reserved"under Disk management

I have 2 nodes Windows 2008 cluster servers.  All disks show online under Failover cluster manager -Storage.  The SAN disks show as "Reserved" under Storage -Disk Management.

I have tried to clear persist reservations and run cluster validation.  In the validation report, there are no errors.  I test the server failover and it works properly too.

However, there are some warnings in Windows Logs -Storage Manager for SANS

Does anyone have an idea if it is a problem?  Can I ignore the warnings?

Thanks in advance.
