DLT_and_DAT_Media_Loaders

 This information applies to TLZnx and TZ8nn classes of DLT
 and DAT loaders.

 DLT and DAT tape loaders treat their robotic devices and
 tape devices as logical units of the device target ID. The
 are four parts to the naming convention with this type of
 robotic loader:

 ·    The name begins with a prefix of MK for the tape
 device and GK for the robotic device.

 ·    The prefix is followed by a letter indicating the
 physical SCSI bus to which the device is connected to the
 host system. For devices connected to the first bus
 detected at boot time, the letter is A, for the second
 bus detected, B, and so on. 

 ·    The next part is a number corresponding to the SCSI
 target ID. 

 ·    The last part is a two-digit number corresponding to
 the SCSI target ID logical unit number. Because tape
 drives in a DLT or DAT loader are always at logical unit
 0, the last two digits are 00. The last two digits for
 the robotic device are 01.

 MKA400 is the name of a tape device connected to the
 first SCSI bus seen at boot time, at target ID 4. GKA401
 is the name of the robotic device, and the name of the
 robotic unit corresponding to the tape device MKA400.
