8.1.8 Peripheral Device Type Parameters for Various Operating Systems
With an in-band connection, a host computer cannot “see” a RAID controller UNLESS the fol-
lowing have been configured:
1. A logical unit has been created.
or
At least one logical unit is mapped to a host ID or LUN via the RS-232/LCD keypad inter-
face.
2. Host bus connection is established.
or
The RAID subsystem/controller is configured to appear as a peripheral device on the
channel bus connected to a host computer.
With a brand new array, there is no association between disk drive configurations and the log-
ical ID/LUN presentations on the host bus. If users want to start configuring a RAID system
from an application server before any RAID configuration is made, the host will not be able to
“see” the RAID subsystem. In order for a host to “see” the subsystem, it will be necessary to
define the controller as a peripheral device.
Different host operating systems require different adjustments. See the tables below to find
the proper settings for your host operating system. References to “Peripheral Device Quali-
fier” and “Device Support for Removable Media” are also included.

NOTICE!
There is no need to configure the Peripheral Device setting if you are trying to manage a RAID
subsystem from a RAIDWatch station through an Ethernet connection (to the Bosch sub-
system’s Ethernet port). An Ethernet connection to RAID uses TCP/IP as the communication
protocol.
