Fabric Zoning And Lun Security For Multiple Operating Systems; Connecting The Disk Array; Adding The New Device Paths To The System; Multi-Cluster Environment - HP XP20000/XP24000 Configuration Manual

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

.
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

HP LUN Configuration and Security Manager XP and XP Array Manager for the XP24000/XP20000
disk array offer the ability to limit access to a given host to a specific host/WWN.
Security must be enabled for LUN isolation when multiple hosts connect through a shared array
port. See the HP StorageWorks SAN Design Reference Guide (http://www.hp.com/go/sandesign)
for fabric zoning and LUN security configuration rules.

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.

Adding the new device paths to the system

After configuring the FCAs and to ensure the new devices are recognized, some FCA drivers require
you to configure each LUN individually (either through the driver configuration file or in /kernel/
drv/sd.conf).
