Figure 4 Multi-cluster environment
.
Within the 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.
WARNING!
For OpenVMS — HP recommends that a volume be presented to one OpenVMS cluster or stand
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 with multiple operating systems to the same switch and fabric using
appropriate zoning and LUN security as follows:
Storage port zones can overlap if more than one operating system needs to share an array port.
Heterogeneous operating systems can share an array port if you set the appropriate host group
and mode. All others must connect to a dedicated array port.
Use LUN Manager for LUN isolation when multiple hosts connect through a shared array port.
LUN Manager provides LUN security by allowing you to restrict which LUNs each host can access.
