WARNING! For OpenVMS - HP recommends that a volume be presented to one OpenVMS cluster or stand 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.

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 between hosts and volumes (LUNs) in the disk array. This process is also called "LUN mapping."

WARNING!
For OpenVMS
—
HP recommends that a volume be presented to one OpenVMS cluster or stand
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.

Configuring FC switches
OpenVMS supports Fibre Channel only in a switched fabric topology. Refer to the switch documentation
to set up the switch.
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.
Creating Fibre Channel zones connecting the host systems to the XP ports. Refer to your switch
manufacturer's documentation for information on setting up zones.
4.
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 between hosts and
volumes (LUNs) in the disk array.
This process is also called
“
LUN mapping.
”
In XP Remote Web Console and XP Command View,
LUN mapping includes:
