HP StorageWorks Disk Array XP operating system configuration guide for OpenVMS XP24000, XP12000, XP10000, v01 (A5951-96136, June 2007)

Figure 2 Multi-cluster environment
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.
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:
• 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.
• Use HP StorageWorks XP Secure Manager for LUN isolation when multiple hosts connect through
a shared array port. Secure Manager provides LUN security by allowing you to restrict which
LUNs each host can access. For detailed procedures, refer to HP StorageWorks XP Secure Manager
User's Guide available at:

Configuring FC switches
OpenVMS supports Fibre Channel only in a switched fabric topology. Refer to the switch documentation
to set up the switch.
