The Parity bit specifies whether to check the SCSI bus parity. The specifications
are as follows.
0: Do not check the SCSI bus parity.
1: Check the SCSI bus parity (default).
Maximum Parity Retries specifies the maximum number of retries after a parity
error occurs in the Command Out Phase, Message Out Phase, or Data Out

The Transport Element Address indicates the autoloader transport system. The

The Source Address specifies the location of the cartridge to be transported. The
Destination Address specifies the transport destination of the cartridge.
The Source Address and Destination Element Address are set to a Storage

the setting is other, the command is terminated with a CHECK CONDITION.
The sense key is ILLEGAL REQUEST and ASC/ASCQ is INVALID
ELEMENT ADDRESS.
If this command is received when there is no cartridge in the Source Element or
