Error Message:

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 device on the shared SCSI bus. The disk might have gone offline or failed. Another node might have taken control of the disk or a SCSI bus reset command was issued on the bus that caused the loss of reservation.

User Action:

Check disk status and configuration.
