• 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. Table 3 Fabric zoning and LUN security settings Environment OS Mix Fabric Zoning LUN Security Standalone SAN (non-clustered) Clustered SAN Multi-Cluster SAN homogeneous (a single OS type present in the SAN) Not required heterogeneous (more than one OS type present in the SAN) Required Must be used when multiple hosts or cluster nodes connect through a shared port Connecting the disk array The HP service representative connects the disk array to the host by: 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. Defining the paths Use XP Remote Web Console (shown), or XP Command View to define paths (LUNs) between hosts and volumes in the disk array. This process is also called "LUN mapping." In XP Remote Web Console and XP Command View, LUN mapping includes: • Configuring ports • Enabling LUN security on the ports • Creating host groups • Assigning Fibre Channel adapter WWNs to host groups • Mapping volumes (LDEVs) to host groups (by assigning LUNs) 16 Installing and configuring Tru64 for the XP disk array

Connecting the disk array
The HP service representative connects the disk array to the host by:
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.
Defining the paths
Use XP Remote Web Console (shown), or XP Command View to define paths (LUNs) between hosts
and volumes in the disk array.
This process is also called “LUN mapping.” In XP Remote Web Console and XP Command View,
LUN mapping includes:
•
Configuring ports
•
Enabling LUN security on the ports
•
Creating host groups
•
Assigning Fibre Channel adapter WWNs to host groups
•
Mapping volumes (LDEVs) to host groups (by assigning LUNs)
