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.

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.

Connecting the disk array

The HP service representative connects the disk array to the host by:
•
Verifying operational status of the disk array channel adapters, LDEVs, and paths.
•
Connecting the Fibre Channel cables between the disk array and the fabric switch or host.
•
Verifying the ready status of the disk array and peripherals.
