Troubleshooting
About this task
v The library consists of the following CRUs (Customer Replaceable Units):
– Control Card (electronics, processor, memory)
– Power Supply
– Drive Sled (drive plus drive-to-library connectivity)
– Library Enclosure (accessor, Operator Control Panel display)
– Cartridge Magazines
v Other possible Replacement Parts are
– Data cartridges
– Cables/Terminator
Important: Before any CRU is replaced, after the problem is found, and after any listed actions are
completed in the Troubleshooting table, be sure to review the “Procedures for isolating CRU problems”
on page 194 to help confirm the failing CRU.
The table outlines the starting points for all service issues. Find the reason that closest resembles the
problem you are experiencing and complete the listed action. If you are unable to correct the problem,
create a prioritized list of replacement parts required. Select only one CRU at a time, starting with the
most likely, based on the “Procedures for isolating CRU problems” on page 194 or the error code listing.
After all troubleshooting efforts are exhausted, see “Contacting IBM technical support” on page 219.
After the problem is corrected, run Library Verify (Operator Control Panel: Service > Library Verify) to
ensure that all library components are functioning properly before normal library operations are resumed.

Problem Solution
INSTALLATION/CONFIGURATION
Unable to configure 3 logical
libraries with 3 drives (2 half
height drives and 1 full height
drive) installed.
The 2 half height drives must be in drive positions 1 and 2 (the lowest drive
positions in the library) and the full height drive must be in the remaining drive
position. For information, seeAppendix B, “SCSI element types, SCSI addresses,
and physical configurations,” on page 285.
Installation and Configuration
1. See “Installation problems” on page 193.
POWER
Library does not power ON
1. Complete “Isolating a power supply problem” on page 194.
The Operator Control Panel is
blank or frozen
1. Power cycle the library.
2. If possible, log on to the Web User Interface and check the error log (Service
Library > View Logs). Look up the error code and try to resolve. See “Error
codes” on page 201.
3. Upgrade or reinstall the latest library firmware. To download the latest library
firmware, visit http://www.ibm.com/support.
v If the problem is corrected, run Library Verify before normal library
operations are resumed. See “Service: Library Verify” on page 108.
v If the problem persists, refer to “Contacting IBM technical support” on page
219.
