Reservation of cluster disk 'name' has been lost. Please check your system and disk configuration.

Explanation:

The Cluster service had exclusive use of the disk but lost reservation of the disk device on the shared SCSI bus. The disk might have gone offline or failed. Another node might have taken control of the disk. A SCSI bus reset command might have been issued on the bus and caused the loss of reservation.

User Action:

Check disk status and configuration.
