- _s_t_a_c_k_e_r is an administrative utility used to move tapes between a robotic
- tape library's slots and drive(s). _s_t_a_c_k_e_r currently supports the
- Exabyte 10i and 10e, the DLT2500, DLT2500xt, DLT2700, DLT2700xt, DLT4500,
- DLT4700, the IBM Magstar (3590) and IBM Magstar MP (3570), the SGI DLT-
- 7000 autoloader (Minivault), the Fujitsu Computer Products of America
- (FCPA) M1016/M1017, M2483 and M2488 3480/3490 drives, and all tape robots
- that conform to the SCSI-2 Medium Changer command set.
-
- The _d_e_v_i_c_e argument is used to specify the special device that will be
- used to control the stacker. This argument can be ignored if the
- environment variable SSSSTTTTAAAACCCCKKKKEEEERRRR____DDDDEEEEVVVV is set. The command line specification
- of a device overrides the environment variable.
-
- The special device nodes used to control tape robots can be found in the
- directory /_d_e_v/_s_c_s_i. (See _d_s(_7_M) for more information.) The entry that
- corresponds to the SCSI bus and target ID of the robotic control
- interface should be used. For example, the SGI DLT-7000 autoloader and
- Exabyte 10i have a SCSI target ID separate from its internal tape drive.
- The the DLT2500 and DLT2700 uses the same SCSI target ID (wih different
- LUN) as their associated tape drive. The IBM 3590 can also be configured
- in a similar fashion.
-
- The _h_i_n_v(_1_M) utility will list any robotic device that uses a separate
- LUN in the following form (with X, Y and Z set to the appropriate
- values):
-
- Jukebox: unit X, lun Y on SCSI controller Z
-
- This program requires root privilege to access the /_d_e_v/_s_c_s_i devices. If
- non-privileged access is required to the robot, simply change the
- permissions on the /_d_e_v/_s_c_s_i device controlling the stacker. (See
- _c_h_m_o_d(_1).)

- The Fujitsu devices use half-inch tape cartridges. The M1016/M1017 are
- 18-track IBM 3480-compatible drives, and do not use the SCSI-2 Medium
- Changer command set. The M2483 is a 36-track IBM 3490-compatible drive.
- The M2488 is like the M2483, but includes SCSI-2 Fast and Wide support.
-
- The Fujitsu devices all use the same SCSI target ID for tape and robotic
- control. However, while the M1016/M1017 use SCSI LUN 0 for both tape and
- robotic control, the M2483 and M2488 devices use LUN 0 for the tape and a

- separate LUN for the robot. The robot LUN is changeable, but is set to 4
- at the factory.
-
- The Fujitsu robotic control is actually performed with what is called an
- autoloader. An autoloader is dedicated to a single drive, as opposed to
- being able to potentially handle multiple drives like the other robotic
- devices.
-
- Fujitsu autoloaders use a tape magazine. The Automatic Cartridge Loader
- (ACL) style of autoloader accepts a 5- or 10-tape magazine, and is
- available with all the drive models. The Flush-mounted ACL (FACL) style
- accepts a 7-tape magazine, and is available on only the M2483 and M2488.
-
- Unlike the other robotic devices described herein, the Fujitsu model
- numbers do not indicate if the tape drive is equipped with a tape robot.
- Invoking _s_t_a_c_k_e_r for a Fujitsu M1016/M1017 that is not equipped with an
- autoloader causes the following message to be displayed: "ERROR: Fujitsu
- M1016/M1017 drive lacks autoloader." This is done because this is the
- only device discussed here for which it is not possible to determine the
- existence of a robotic device from either the device's model number or
- the output of _h_i_n_v(_1_M).

- All bins are numbered starting from 1 to the number supported by the
- device. The internal tape drives (if there are more than one) are
- numbered starting at 1 as well. For example, the Odetics 2640 library's
- bins are numbered from 1 to 264, and its tape drives are numbered from 1
- to 3.

- Unload a tape from the specified tape drive into the specified

- such unload request with the following message: "NOTE: Fujitsu

- The DLT2700 must have the mode select key set to automatic in order for
- the software to be able to control the stacker's robotics. Automatic
- mode is represented by a square made of arrows.
-
- The IBM Magstar MP stacker must be in the "Random" or "Random (2-LUN)"
- mode to be controllable by the software. This mode is configured via the
- control panel on the 3590 drive. When set to 2-LUN mode, the drive will
- be LUN 0, and the stacker is LUN 1. In "Random" mode, only LUN 0 exists
- and stacker operations must be directed there.
-
- As a Fujitsu autoloader is dedicated to a single drive, and since the
- drive number parameter defaults to 1, the ----llll and ----uuuu options never need to
- include a Fujitsu drive number.
-
- The SGI DLT-7000 autoloader (Minivault) is also dedicated to a single
- drive and hence the drive number need not be specified. The SGI DLT-7000
- autoloader is shipped from the factory with the loader set for target ID
- 1, and the drive set for target ID 2. These may have been changed at your
- individual site.
-
- The Fujitsu M1016/M1017 device's SCSI command to move media into or out
- of a bin contains no load or unload field. Its operation is dependent on
- the state of the referenced bin and the device's single drive. Issuance
- of this command results in a drive load operation if the bin contains a
- tape, an unload operation if the drive contains a tape from that bin, or
- an error if the bin was empty when the magazine was inserted into the ACL
- or FACL. If a tape loaded from another bin is in the drive when this
- command is issued, this tape is automatically unloaded to its originating
- bin before the tape in the referenced bin is loaded.
-
- Hence, the ----llll and ----uuuu options can be used interchangeably with the Fujitsu
- M1016/M1017. The result of issuing either command will be a load or
- unload operation, as appropriate for the current state of the bin
- referenced.
-
- BBBBUUUUGGGGSSSS
- The DLT2700 does not respond to some error conditions with the expected
- SCSI error messages. For example, moving a tape to a bin that is already
- occupied will result in an "invalid field in CDB" message (that is the
- error returned by the 2700) rather than a "destination element full"
- message.
