Ra4000 Configuration; Array Configuration Utility - Compaq StorageWorks 4000 - RAID Array White Paper

Compaq RAID Array 4000 Storage System: Deployment and Configuration
4. Boot to DOS on the server
5. Copy the latest CPQFC.HAM driver (version 2.00 or greater) to C:\NWSERVER from
NSSD 5.10 or later.
6. Ensure that the CPQFC.HAM driver will be loaded for new Fibre Channel Host Adapter(s)
by editing the server's STARTUP.NCF file and either:
7. Add new "load" command(s) for CPQFC.HAM using the "slot = n" command line parameter
where "n" is the slot number of the new Fibre Channel Host Adapter(s).
OR
8. Use a single instance of "load cpqfc.ham" without a "slot =" command line parameter so that
the driver will load for all supported Fibre Channel Host Adapters installed in the server.
9. Restart the server. CPQFC.HAM will automatically detect and utilize new redundant paths.

RA4000 Configuration

Compaq has developed the following utilities to simplify configuration of an RA4000 storage
system.

Array Configuration Utility

Fibre Fault Isolation Utility
Compaq Redundancy Manager
Array Configuration Utility
The Compaq Array Configuration Utility (ACU) is provided on the Compaq SmartStart and
Support Software CD and uses a graphical interface to streamline configuration of RA4000s. The
ACU contains intuitive online configuration wizards that provide guided paths for complete array
configuration. The ACU also contains customized paths for administrators needing complete
control over configuration options.
Version 1.20 and later of the ACU provides an interface to intelligent features of the RA4000
Controller that make it easy for administrators to configure, modify, expand, manage, and
monitor their storage.
Using the ACU, an administrator can quickly assign physical drives to an array. Up to 4 drives
can be assigned as online spares, and from 1 to 32 logical drives can be created per controller.
The ACU steps through each logical drive configuration until all space is allocated. Fault
tolerance levels can be selected on a logical drive basis.
Custom configuration paths allow the administrator to examine the details of both logical and
physical views and to make specific configuration changes if necessary. Graphical views of the
array and the logical drives make it easy to visualize how the storage is configured.
Capacity expansion is done at the array level, not at the logical drive level. In most cases, all disk
drives attached to a controller should be grouped together into a single array. This allows for the
most efficient use of RAID redundancy.
