Replacing the Magazine in the Stacker

To replace the magazine in the stacker, follow these steps:

1. Press the Open button.

2. Make sure that the magazine door is moved all the way to the left.

3. Holding the magazine by its handle, slide it into the stacker doorway, as shown in

Figure 5-6. Since the magazine is slotted, you can reinstall it only in the correct

orientation.

4. Move the locking lever at the left to the closed position to secure the magazine.

5. Slide the door closed; make sure it is fully closed before proceeding.

IRIX Stacker Control Commands

If you issue SCSI-2 medium changer commands to the DLT23500XT stacker:

• random access is enabled to the media stored in the magazine slots

• sequential access is disabled to the media supported automatically in autoloading

mode

If you do not issue the SCSI-2 medium changer commands, the default mode of

operation is sequential access to the media supported automatically in autoloading

mode.

Autoloading is implemented as a side effect of the SCSI UNLOAD command if an unload

is speciﬁed after the tape is rewound back into the cartridge and the cartridge is moved

back from the drive to the magazine slot form which it came. The cartridge in the next

slot is moved from the magazine into the drive and made ready. If the next slot is empty,

or the cartridge unloaded was for the last slot in the magazine, no cartridge is loaded into

the drive.

The DLT2500XT stacker tapes can also be moved from the command line of your

terminal or workstation. Tapes from speciﬁc slots in the magazine can be moved into the

drive for reading or writing purposes. To load a cartridge from position 0 in the magazine

into the stacker’s drive, use the -l argument and enter a command such as the following:

% /usr/sbin/stacker -l 0 /dev/scsi/sc3d6l0
