Applies to:

Solaris Cluster Geographic Edition - Version 3.1x to 4.3 [Release 3.1 to 4.3]

Goal

This document shows how to put back reservation keys on shared cluster disks, after they have been "scrubbed".
In Sun/Solaris Cluster 3.x software, for various reasons, SCSI3 reservation keys and reservations are sometimes removed from disks on purpose (for example, when moving storage area network(SAN) attached LUNs between clusters).

If a disk is inadvertently scrubbed, later when the cluster node accesses the device, it can cause "Reservation conflict" panic.
