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 library name to which the drive is to be assigned. This parameter is required. 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.

Device

Enter the name of the device as known to the device driver. If this parameter is not specified, the server cannot access the drive.  If the drive will only be accessed by a NAS data mover, the DEVICE parameter can be omitted.

Element

Enter the element address of the drive within a SCSI library. 

The following notes apply to the element parameter:

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. This parameter is optional. The default is Yes.

Yes The drive is online.
No The drive is not online.

Cleaning Frequency

Enter the value for the cleaning frequency you would like to establish for the selected drive. The default is None.

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. Note: If a drive is attached only to a NAS file server (no connection to a storage agent or server),  do not specify Asneeded.  
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.
