HP StoreEver MSL2024 User And Service Manual: Detection Problems After Installing A Parallel Scsi Drive

If the library is detected by the operating system, but not by the application software:
Refer to the documentation included with your backup application for instructions on
how to verify proper installation. Some backup software packages require an additional
module to communicate with the robotics.
If the library is detected by the operating system, but is listed as an unknown or generic
device:
Make sure that the proper device driver, if applicable, is installed for the device. Check
your software provider's website for the latest drivers and patches.
NOTE:
make sure it is not in conflict with the application software.
If you continue to have problems with a SAS library, check the following:
Ensure that the device is compatible with the SAS host adapter and backup application you
plan to use. For a list of compatible SAS host bus adapters and application software, check
with your SAS host adapter manufacturer, backup application vendor, or the BURA Data
Agile Compatibility Matrix at http://www.hpe.com/info/ebs.
Verify that your HBA is supported by the host computer and qualified with the library. For
current HBA compatibility information, see the BURA Data Agile Compatibility Matrix at
www.hpe.com/info/ebs.
Ensure you are using a compatible, high-quality cable. See the product QuickSpecs for a
list of supported cables.

Detection problems after installing a parallel SCSI drive

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 can 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 library or
drive 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:
134 Troubleshooting
Many backup applications use their own drivers. Before installing a driver,
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
SCSI addresses" (page
"MSL2024 parallel SCSI tape drive default
