5 NonStop

You and the HP service representative each play a role in installation. The HP service representative
is responsible for installing the disk array and formatting the disk devices. You are responsible for
configuring the host server for the new devices with assistance from the HP service representative.
The HP NonStop operating system runs on HP S-series and Integrity NonStop servers to provide
continuous availability for applications, databases, and devices. The NonStop OS and servers
support high transaction volumes and complex mixed workloads. An open application development
environment supports common standards, including Java, CORBA, SQL, OBDC, JDBC, HTTP,
TCP/IP, and application programming interfaces.

Installation roadmap

Perform these actions to install and configure the disk array:
1. "Installing and configuring the disk array" (page 52)
"Defining the paths" (page 52)
"Setting the host mode and host group mode for the disk array ports" (page 53)
"Setting system option modes" (page 54)
"Configuring the Fibre Channel ports" (page 55)
2. "Installing and configuring the host" (page 55)
"Loading the operating system and software" (page 17)
"Installing and configuring the FCSAs " (page 55)
"Fabric zoning and LUN security for multiple operating systems" (page 56)
3. "Connecting the disk array" (page 56)
"Verifying disk array device recognition" (page 56)
4. "Configuring disk devices" (page 56)

Installing and configuring the disk array

The HP service representative performs these tasks:
Assembling hardware and installing software
Loading the microcode updates
Installing and formatting devices
After these tasks are finished, use XP Remote Web Console, P9000 or XP Command View Advanced
Edition Software, or XP Array Manager to complete the remaining disk array configuration tasks.
If you do not have these programs, your HP service representative can perform these tasks for you.

Defining the paths

P9000 or XP Command View Advanced Edition Software or XP Remote Web Console (shown) 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
