User guide

Users of a Compaq single channel array controller should consider upgrading
to the new Smart Array 431 Controller. This appendix provides an upgrade
procedure for moving arrayed drives to the Smart Array 431 Controller. All
user data and configuration information will be retained after the upgrade
process.
Array configuration information is transferred automatically during the
upgrade process. However, this is a one-way process. After upgrading to the Smart Array
431 Controller, a manual reconfiguration procedure is required to move the drives and
data back to the previous array controller..
To upgrade your system with a new Smart Array 431 Controller:
1. Perform a complete backup of all affected drives. This is a safety
precaution only. If properly executed, this upgrade procedure will not
affect the arrayed data or drive location.
2. Upgrade your OS device driver to the new Smart Array 431 Controller
driver. The new drivers have been optimized to support the latest
features and capabilities of the Smart Array 431 Controller. The driver
upgrade process is OS-dependent but is not difficult. See the readme
information for your OS on the Compaq SmartStart and Support
Software CD, or see Chapter 7, depending on your OS.
