Novell NETWARE 6-DOCUMENTATION Manual page 778

To see a list of storage devices and their names, execute the LIST STORAGE
ADAPTERS command at the server console prompt. The screen lists each
device adapter, followed by a list of devices driven by that adapter. In the
following example, the first line identifies an IDE disk adapter. The second
line identifies a hard disk operated by that adapter:
[V025-A0] NOVELL IDE HOST ADAPTER MODULE
[V025-A0-D1:0] QUANTUM FIREBALL_TM3840A
The bracketed letters and numbers at the beginning of each line are the device
name. The device name identifies the adapter or device, as follows:
Vendor Number
Adapter Number
Device Number
Logical Unit Number
Vendor number. A unique number specific to the device vendor.
Adapter number. The instance of the adapter in the server. In the
example, A0 identifies the first instance of an adapter installed in the
server. Adapter numbers are unique. The second adapter installed in the
server will have adapter number A1, even if the adapter is of the same
type as adapter A0.
Device number. The number of the disk or other device. For a SCSI disk,
this is the target ID, usually set by a jumper on the hard disk. For an IDE
disk, this number represents the bus from the IDE controller. IDE
numbers range from D0 through D3, representing the primary, secondary,
tertiary, or quaternary bus.
Logical unit number (LUN). The LUN identifies individual devices
when more than one device is attached to one bus. For example, one IDE
bus might be attached to two disks, a master and a slave. LUN 0
represents the master and LUN 1 represents the slave. However, because
disk manufacturers rarely use the logical unit number to identify hard
disks, the LUN almost always appears as 0.
The Device name represents the device in all Novell utilities and console
commands, including MONITOR, LIST DEVICES, etc.
Fault tolerance systems such as Hot Fix use the Device name to report that
data blocks on disks have relocated.
