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.

QLogic and Emulex FCAs must be in separate zones (a QLogic zone and an Emulex zone)

whether the FCAs are in the same or separate servers.

If booting over the SAN, within a server, the booting FCAs must be from the same vendor. Addi-

tional data storage FCAs can be from a different vendor.

Environment

Standalone SAN

(non-clustered)

Clustered SAN

Multi-Cluster SAN

If you plan to use clustering, install and configure the clustering software on the servers. Clustering

is the organization of multiple servers into groups. Within a cluster, each server is a node. Multiple

clusters compose a multi-cluster environment. The following example shows a multi-cluster environ-

ment with three clusters, each containing two nodes. The nodes share access to the disk array.

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.
