To create CSPs:   

1.

 

Insert the SmartStart CD into the CD-ROM drive tray of a server with a bootable
CD-ROM drive. The server does not need to be the one in which you are going to
install the controller.

2.

 

Restart the server.

3.

 

On the 

Compaq System Utilities

 screen, select 

Create Support Software.

4.

 

On the 

Diskette Builder

 screen, select 

Create Support Software From CD

Only.

5.

 

Scroll down the list and select the support software for the operating system that
you are using.

6.

 

Follow the on-screen instructions to create the diskettes. Depending on your
operating system, you may need to use up to six blank diskettes.

Detailed instructions for installing the device drivers are given in the README files
on the CSPs.

Updating the Compaq Insight Manager Agents

If you are installing the controller as additional storage, you may now update the
Compaq Insight Manager agents if new versions are available. Refer to the
documentation that is included with Compaq Insight Manager for the correct
procedure to update the agents.

You can obtain the Compaq Insight Manager Agents from your local Compaq
reseller or Compaq authorized service provider. The latest versions of Compaq
Insight Manager and Management Agents are also available for download at

www.compaq.com/manage.

If the new agents do not function correctly, you may also need to update
Compaq Insight Manager.
