Fabric Zoning And Lun Security For Multiple Operating Systems; Multi-Cluster Environment - HP StorageWorks XP10000 - Disk Array Configuration Manual

Clustering is the organization of multiple servers into groups. Within a cluster, each server is a node.
Multiple clusters compose a multi-cluster environment. The following example shows a multi-cluster
environment with three clusters, each containing two nodes. The nodes share access to the disk array.

.
Within the Storage Area Network (SAN), the clusters may be homogeneous (all the same operating
system) or they may be heterogeneous (mixed operating systems). How you configure LUN security
and fabric zoning depends on the operating system mix and the SAN configuration.

alone system at a time. Volumes should not be presented to allow them to move between stand alone
systems and/or OpenVMS clusters, as this can lead to corruption of the OpenVMS volume and data
loss.

Fabric zoning and LUN security for multiple operating systems

You can connect multiple clusters of various operating systems to the same switch and fabric using
appropriate zoning and LUN security as follows:
Storage port zones may overlap if more than one operating system needs to share an array port.
Heterogeneous operating systems may share an XP array port if you use Secure Manager and set
the appropriate host group and mode. All others must connect to a dedicated XP array port.
HP recommends that a volume be presented to one OpenVMS cluster or stand
