DEFINE DRIVE (Define a Drive to a Library)

Use this command to define a drive that TSM can use to access data on storage volumes. Each drive is assigned to a single library. You must define this library before you issue this command. You can define more than one drive for a given library by issuing the DEFINE DRIVE command once for each drive. Stand-alone drives always require a manual-type library. For additional information, see Administrator's Guide.

Privilege Class

To issue this command, you must have system privilege or unrestricted storage privilege.

Notes:

  1. The ELEMENT parameter is required for drives in SCSI libraries.

  2. ACSDRVID is required for drives in ACSLS libraries. This parameter is not valid for non-ACSLS libraries.

Parameters

lib_name (Required)
Specifies the name of the library to which the drive is assigned. This parameter is required for all drives, including stand-alone drives. The specified library must have been previously defined by using the DEFINE LIBRARY command.

drive_name (Required)
Specifies the name that is assigned to the drive. The maximum length of this name is 30 characters.

DEVIce (Required)
Specifies the name of the device (the special file name) that corresponds to the drive. For example, you might specify /dev/mt2 or /dev/rop2.

To access a drive that is device type REMOVABLEFILE, use a mount point such as, /cdrom.

See the device special file names in the following table. In this table, x denotes any number from 1 to 9.

Special File Name Description
/dev/mtx Used by all TSM-supported tape drives (not supported by IBM hardware device drivers)
/dev/lbx Used by most TSM-supported SCSI libraries
/dev/ropx Used by all TSM-supported optical drives
/dev/rmtx Used by the GENERICTAPE and 3570/3590 device types
/dev/smcx Used by 3570 and 3575 libraries, and used to define the Automatic Cartridge Facility feature of the IBM 3590 B11 as a library
/dev/lmcpx Used by 349X automatic tape libraries
/dev/cdx Used by REMOVABLEFILE device type (CDROM)

ONLine
Specifies whether the drive is available for use. This parameter is optional. The default is YES.

Yes
Specifies that the drive is available for use.

No
Specifies that the drive is not available for use.

ELEMent=address
Specifies the new value to be used for the drive's element address within a SCSI library. This parameter is optional. TSM needs the element address to connect the physical location of the drive to the drive's SCSI address. To find the element address for your library configuration, access the TSM Web site at: http://www.tivoli.com/tsm . At this URL, follow the links to device information. You will need to click on your product and platform and then scroll to the required device. When you click on your selected device, you will get the element address.

ACSDRVID
Specifies the ID of the drive that is being accessed. The drive ID is a set of numbers that indicates the physical location of a drive within an ACSLS library. This drive ID must be specified as a,l,p,d, where a is the acsid, l is the LSM (library storage module), p is the panel number, and d is the drive ID. TSM needs the drive ID to connect the physical location of the drive to the drive's SCSI address. See the STK documentation for details.

CLEANFREQuency
Specifies how often the TSM activates drive cleaning. You must have a cleaner cartridge checked into the library's volume inventory to use this parameter. This parameter is optional. The default is NONE.
Note:Use drive cleaning that is controlled by TSM only for SCSI libraries that do not have automatic drive cleaning support in their device hardware.

NONE
Specifies that TSM does not track cleaning for this drive. Use this for libraries that have their own automatic cleaning.

ASNEEDED
Specifies that TSM loads the drive with a checked-in cleaner cartridge only when a drive reports to the device driver that it needs cleaning.

value
Specifies (in gigabytes) how much data to process on the drive before TSM loads the drive with a cleaner cartridge. TSM resets the gigabytes-processed counter each time it loads a cleaner cartridge in the drive.

Examples

Task

You have defined a manual tape library that is named MANLIB. You now want to inform the server that you have a tape drive that can be used to access storage media. You choose the name TAPEDRIVE3 for this drive.

Command:
define drive manlib tapedrive3 device=/dev/mt0

Task

Define a drive in an ACSLS library with a library name of ACSLIB and a drive name of ACSDRV1 .

Command:
define drive acslib acsdrv1 device=/dev/mt0 acsdrvid=1,2,3,4

Task

Define a drive for a device type of REMOVABLEFILE (CDROM).

Note:This command uses a UNIX mount point as the device. Refer to the Administrator's Guide for more information.

Command:
define drive manlib cdrom device=/cdrom
