Defining an Automated Drive

To define a drive to a library, complete the following fields and then click Finish, or click Cancel to end this task.

Library Name

Enter the name of the library to which the drive is to be assigned. This parameter is required for all drives including stand-alone drives. The specified library must have been previously defined.

Drive Name

Enter the name assigned to the drive. This parameter is required. The maximum length of this name is 30 characters.

Serial 

Enter the serial number of a drive within a SCSI library.  The following options are available for the serial parameter:

Autodetect Specify that the serial number will be automatically detected later when a path to the drive is defined.
serial number Enter the serial number.

When you enter a number for the serial parameter, if a path to the drive already exists, then the number is compared to the one already detected by the server.  If the numbers do not match, the command will fail.

Element

Enter the element address of the drive within a SCSI library. This field is valid only for drives in SCSI libraries when the operation is performed from a server that is a  library manager.

The following options are available for the element parameter:

Autodetect Specify that the element number will be automatically detected later when a path to the drive is defined.
address Enter the element address.

 If the library in which the drive is located does not support the Read Element Status SCSI command, and you do not enter the ELEMENT parameter, the command will fail with a Tivoli Storage Manager error message.

The server 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, consult the manufacturer's information.

Device On-Line

Select an option to specify if the drive is available for use. This parameter is optional. The default is Yes.

Yes The drive is on-line.
No The drive is not on-line.

Cleaning Frequency

Enter the value for the cleaning frequency you would like to establish for the selected drive. The default is None. This parameter is not valid for externally managed libraries, for example, 3494 libraries or STK libraries managed under ACSLS.

The following are possible values:

None Specifies that the server does not track the need for device cleaning. Some libraries 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. 
Gigabytes Specifies a value in gigabytes, from 1 to 9999. This indicates how much data processing will occur before the server loads the drive with a cleaner cartridge. Drive cleaning will still take place when a drive indicates that cleaning is required.

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.
