Examples
Following is an example of a listing of a server’s storage adapter and the
associated storage device:
[V025-A0] NOVELL IDE HOST ADAPTER MODULE
[V025-A0-D1: 0] QUANTUM FIREBALL_TM3840a
The first line in the example identifies an IDE disk adapter. The second line
identifies a hard disk operated by that adapter. The second line is indented to
indicate that the device is associated with the adapter in the preceding line.
The bracketed numbers at the beginning of each line comprise the device
name. The device name identifies the adapter or device, as follows:
 Vendor number. A unique number specific to the device vendor.
 Adapter number. The instance number of an adapter registered with
NWPA. In the example, A0 identifies the first instance of an adapter
installed in the server.
 Device number. The number of the disk or other device.For a SCSI disk,
this is the SCSI 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 can 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.
