Device Redirection
With the disk and network resources existing on the IOPs, but
“owned” and accessed by the CEs, the AA 4000 software has to have
a way to make this happen. The method is called device redirection.
First, let’s start with a list of devices than can be redirected:
• SCSI Disks
• SCSI Tape Drives
• CD-ROMs
• Ethernet Adpaters
• Floppy Disk Drives
• Keyboard and Mouse
• Serial Ports
These devices exist on the IOP, but when the AA 4000 software
loads during the Windows NT boot process, a configuration file is
checked and all devices that have been configured for redirection no
longer are accessible by the IOP. When the CE boots, it will have
access to the redirected devices.

The list of redirected devices can be found by using the HP AA 4000
Configuration Utility. As seen by the screenshot below, the devices
are redirected by category.
