monitoring and administration. In addition to the regular RS-232C
or Ethernet connection, in-band SCSI can serve as an alternative
means of management communications. In-band SCSI translates
the original configuration commands into standard SCSI commands.
These SCSI commands are then sent to and received by the
controller over the existing host links, either SCSI or Fibre.
5.1.8 Peripheral Device Type Parameters for Various
Operating Systems
IMPORTANT!
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 EonStor subsystem’s
Ethernet port). An Ethernet connection to RAID uses TCP/IP as
the communication protocol.
With an in-band connection, a host computer cannot “see” a RAID
controller UNLESS the following have been configured:
1. (a) A logical unit has been created.
(b) At least one logical unit is mapped to a host ID or LUN via
the RS-232/LCD keypad interface.
2. (a) Host bus connection is established.
(b) 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 logical 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 Qualifier” and “Device
Support for Removable Media” are also included.
