5 Troubleshooting
CAUTION: This library is designed to operate when installed in a rack using the included rack
rails. The MSL2024 and MSL4048 can also be set on a flat surface when mounted in the optional
Rack-to-Tabletop Conversion Kit. Operating the library without one of these kits, such as on a flat
surface without the Rack-to-Tabletop Conversion Kit, could result in device errors. Placing any
weight on top of the device might also cause errors.
CAUTION: Shipping Lock: The shipping lock must be removed for the robotics to operate properly
on the MSL2024 and MSL4048. The device displays a robot move error if the shipping lock is not
removed (see “Removing the shipping lock” (page 45)).

Detection problems after installing a parallel SCSI device
The MSL4048 library will not operate with a full-height tape drive installed in the middle two
half-height drive bays. Verify that the full-height tape drive is installed in a supported position. A
full-height drive may only be installed in either the upper or lower two half-height drive bays.
Problems encountered after installation are often caused by improper parallel SCSI bus configuration,
application software configuration errors, or an incorrectly configured operating system. If the
application software or operating system does not communicate with the device after installation,
determine the extent of the detection problem:
Does the application software detect the tape drive?
Does the application software detect the library?
Does the operating system detect the tape drive?
Does the operating system detect the library?
Does the operating system detect the library, but list it as a generic device?
Based on the extent of the detection problem, check the following:
If neither the application software nor operating system detects the tape drive, or they do not
detect both the tape drive and the library:
Check the SCSI ID and change it if necessary. The default SCSI ID for each tape drive
will be 4 or 5 depending on the library model and drive slot:
MSL2024: For full-height tape drives the default SCSI address is 4. For half-height
drives, the default SCSI address for the bottom drive is 4 and the default SCSI address
for the top drive is 5 as shown in “MSL2024 parallel SCSI tape drive default SCSI
addresses” (page 143).
