Use at the server console to display a list of the storage devices on the server and to register new devices with the server's Media Manager database.
A device can be a disk drive, magneto-optical disc drive, CD-ROM, or any other physical device.
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.
However, because disk manufacturers rarely use the logical unit number to identify hard disks, the LUN almost always appears as 0.
The driver's version or revision number appears at the end of the line.
