Verifying the FCA configuration

After installing the FCAs, verify recognition of the FCAs and drivers as follows:
1. Log into the system as root. Verify that all devices are powered on and properly connected to
the system.
2. Use the prtdiag command (SPARC only) to verify that the FCA is installed properly. Use the
prtconf command and/or browse the /var/adm/messages file to check whether the FCA
driver has attached. Look for the WWN/WWPN of the FCA in the /var/adm/messages file
or use an FCA-specific tool or command.

Clustering and fabric zoning

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
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 needs to 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.
