Figure 4 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 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.

Connecting the disk array

The HP service representative performs the following steps to connect the disk array to the host:
1.
Verifying operational status of the disk array channel adapters, LDEVs, and paths.
2.
Connecting the Fibre Channel cables between the disk array and the fabric switch or host.
3.
Verifying the ready status of the disk array and peripherals.
