Privilege Class

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

Notes:

  1. The ELEMENT parameter is valid only for drives in SCSI libraries.

Parameters

library_name (Required)
Specifies the name of the library to which the drive is assigned.

drive_name (Required)
Specifies the name that is assigned to the drive.

DEVIce
Specifies the name of the device (that is, the special filename) that corresponds to the drive. For example, you might specify /dev/rmt/c0t3d0BEST. This parameter is optional. See the DEVICE parameter description of the DEFINE DRIVE command for special device names.

ELEMent
Specifies the element address of the drive within a SCSI library. This parameter is optional and is only valid for a drive located in a SCSI library. It is not required for drives in a library defined as SHARED. To find the element address for your library configuration, consult the manufacturer's information. You can also access the TSM Web site at: http://www.tivoli.com/support/storage_mgr/tivolimain.html . 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. Click on your selected device to see element addresses.

CLEANFREQuency
Specifies how often the server activates drive cleaning. This parameter is optional. For the most complete automation of cleaning for an automated library, you must have a cleaner cartridge checked into the library's volume inventory. For details on using this parameter for automated and manual libraries, see Administrator's Guide.
Note:Do not use drive cleaning that is controlled by the server for SCSI libraries that have automatic drive cleaning support in their device hardware.

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

ASNEEDED
Specifies that the server 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 will process on the drive before lhe server loads the drive with a cleaner cartridge. The server resets the gigabytes-processed counter each time it loads a cleaner cartridge in the drive.

Consult the drive manufacturer's information for cleaning recommendations. If the information gives recommendations for cleaning frequency in terms of hours of use, convert to a gigabytes value by doing the following:

  1. Use the bytes-per-second rating for the drive to determine a gigabytes-per-hour value.
  2. Multiply the gigabytes-per-hour value by the recommended hours of use between cleanings.
  3. Use the result as the cleaning frequency value.

Examples

Task

Update the drive named DRIVE3 located in the library named AUTO by changing the element address to 119.

Command:
update drive auto drive3 element=119
