The SAN Volume Controller provides clustering support for HP 9000 and HP Integrity servers.
HP-UX version 11.31 supports ServiceGuard 11.18, which provides a cluster locking mechanism called cluster lock LUN. On the SAN Volume Controller, specify the block device name of a virtual disk (VDisk) for CLUSTER_LOCK_LUN variable in the cluster configuration ASCII file. The lock LUN among all cluster nodes must point to the same VDisk. This consistency can be guaranteed by determining the world wide identifier (WWID) of the VDisk. The cluster lock LUN cannot be used for multiple cluster locking and cannot be used as a member of a Logical Volume Manager (LVM) volume group or VxVM disk group.
