alone system at a time. Volumes should not be presented to allow them to move between stand alone
systems and/or OpenVMS clusters, as this can lead to corruption of the OpenVMS volume and data
loss.

Fabric zoning and LUN security for multiple operating systems

You can connect multiple clusters of various operating systems to the same switch and fabric using
appropriate zoning and LUN security as follows:
Storage port zones may overlap if more than one operating system needs to share an array port.
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.

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 Advanced Edition Software 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)
