SCSI bus

SCSI bus

Signal path or line shared by the devices on the same SCSI

 

channel. Information is often sent to all devices throughout the

 

same bus; only the device to which it is addressed will accept it.

slot

A slot is the place within the cartridge storage area, or the Mailbox

 

(Scalar 458 only), where the media is placed. Each slot has a

 

reference position, i.e. row 1, position 1 through position 12

 

(storage slots) and row 1, position 1 through 10 (Mailbox).

terminator

a physical block which tells the SCSI bus that this is the end of the

 

line. A terminator is required at both ends of a SCSI bus. A bus

 

may be terminated internally (on a device inside the host system)

 

or externally on a peripheral device.

unload

The process where the Scalar Library causes a drive to eject a

 

cartridge, then uses the Media Picker to move the cartridge to

 

either a storage slot location, or to a slot in the Mailbox.
