Reserves and monitors SCSI disks for a system, enabling a resource to go online on that system. This agent enables you to specify a list of raw disk devices, and reserve all or a percentage of accessible disks. The reservations prevent disk data corruption by restricting other nodes from accessing and writing to the disks. The DiskReservation agent supports all SCSI-II compliant disks.
An automatic probing feature allows systems to maintain reservations even when the disks or bus are reset. The optional FailFast feature minimizes data corruption in the event of a reservation conflict by causing the system to panic.
Note The DiskReservation agent cannot be used to reserve disks that have multiple paths.
