Figure 3 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.

WARNING!

For OpenVMS

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.

Use 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.
