Fabric zoning and LUN security for multiple operating systems You can connect multiple clusters of various operating systems to the same switch using appropriate switch zoning and array LUN security as follows: • Use LUN Manager for LUN isolation when multiple NonStop systems connect through a shared array port. LUN Manager provides LUN security by allowing you to restrict which LUNs each host can access. • Do not connect other operating systems to the same disk array ports or even use a port that shares a processor with the same port as NonStop systems. • Use SAN switches dedicated to NonStop connections, or solutions that have been qualified by HP. These HP-qualified solutions can include operating systems other than NonStop, but fabric zoning and LUN security must be used to isolate them from the NonStop systems.

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. Verifying disk array device recognition For the NonStop host to recognize disk devices, the disk devices must first be added, configured, and started using the installation procedure described in chapter 2 of the Fibre Channel ServerNet Adapter Installation and Support Guide available at the NonStop Technical Library website: http://h30163.www3.hp.com/ntl/. Configuring disk devices Configure the disk array devices in the same way you would configure any new disk on the host. Creating scripts to configure all devices at once could save you considerable time. See the Fibre Channel ServerNet Adapter Installation and Support Guide, at the NonStop Technical Library website: http://h30163.www3.hp.com/ntl/. To configure the array disk devices, use SCF commands including ADD, START, and INIT as detailed in subsection DISK configuration (ESS Connection) of Chapter 2, Installing an FCSA. 56 NonStop

Fabric zoning and LUN security for multiple operating systems
You can connect multiple clusters of various operating systems to the same switch using appropriate
switch zoning and array LUN security as follows:
•
Use LUN Manager for LUN isolation when multiple NonStop systems connect through a shared
array port. LUN Manager provides LUN security by allowing you to restrict which LUNs each
host can access.
•
Do not connect other operating systems to the same disk array ports or even use a port that
shares a processor with the same port as NonStop systems.
•
Use SAN switches dedicated to NonStop connections, or solutions that have been qualified
by HP. These HP-qualified solutions can include operating systems other than NonStop, but
fabric zoning and LUN security must be used to isolate them from the NonStop systems.

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.
Verifying disk array device recognition
For the NonStop host to recognize disk devices, the disk devices must first be added, configured,
and started using the installation procedure described in chapter 2 of the
Fibre Channel ServerNet

Configuring disk devices

Creating scripts to configure all devices at once could save you considerable time.
