Do not connect other operating systems to the same XP 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 connects the disk array to the host by:

Verifying operational status of the disk array channel adapters, LDEVs, and paths.

Connecting the Fibre Channel cables between the disk array and the fabric switch or host.

Verifying the ready status of the disk array and peripherals.

Use XP Remote Web Console (shown), XP Command View, or XP Command View Advanced Edition

to define paths (LUNs) between hosts and volumes in the disk array.

For non-host mirrored disks, create two identical host groups on two different ports (one port in each

cluster in the array) with identical LUNs in each group.

For host mirrored disks, create two sets of two identical host groups (four total host groups). Configure

one set of two host groups for the Primary (P) path and its backup (B). Assign these two host groups

to two different ports in two different clusters of the disk array, and give each host group access to

separate but identical LUNs. Configure the other set of two host groups for the Mirror (M) and Mirror

Backup (MB) paths. Assign these two host groups to two different ports in two different clusters of the

disk array, and give each host group access to separate but identical LUNs. This arrangement minimizes

the shared components among the four paths, providing both mirroring and greater failure protection.

NOTE:

For the highest level of availability and fault tolerance, HP recommends the use of two XP disk arrays,

one for the Primary disks and one for the Mirror disks.

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 ServerNet adapter WWNs to host groups

Mapping volumes (LDEVs) to host groups (by assigning LUNs)

Installing and configuring NonStop for the XP disk array

Fabric Zoning
