LIST DEVICES
Using LIST DEVICES
LIST DEVICES forces a scan for devices , displays the return list of storage
devices, and registers any new devices with the Media Manager database. This
command does not simply read the database.
When you are installing new storage devices, you can load drivers with a no
scan parameter, and then run LIST DEVICES so that drivers will find their
devices simultaneously.
The command output is returned by the device drivers. The information for
each storage device includes the device number and name, as well as
additional information that varies by device and by manufacturer.
Following is an example of a device listing:
0x0001:[V023-A0-D0:0] SEAGATE ST31051N rev:0530
0x0002:[V023-A0-D0:1] NEC CD-ROM DRIVE:500 rev:2.5
The hexadecimal integer at the beginning of the line is the device’s Media
Manager object ID.
The bracketed numbers comprise the device name that identifies the storage
device, as follows:
 Vendor number. A unique number specific to the device vendor
 Adapter number. The instance number of an adapter registered with
Media Manager. 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.
