Symptoms
When the Recovery Guru on the MDSM shows the error "Virtual Disk Not On Preferred Path" you should manual redistribute the virtual disks.
Cause
When data comes to a redundant, dual Controller MD3000(i) over 5 minutes via the nonpreferred path, the failover controller will start to handle the traffic direct but with the error message "Virtual Disk Not On Preferred Path".
This can have different causes, like a failed connection, changed in the fabric (storage network with iSCSI), the wrong MPIO driver, an unsupported operating system, etc.
