Sun StorageTek SL500 Modular Library System - Version Not Applicable and later
Information in this document applies to any platform.

Purpose

SL500 - Troubleshooting a RLC Card Issue in Library

No robotics movement in library.
Service required light is on.
Customer has reported the library is not functional or moving tapes.

Troubleshooting Steps

The RLC card is difficult to diagnose. One needs to drill down to actually identify a problem that would be associated with this assembly.

Refer to: SL500 Diagnostics/Troubleshooting Manual, PN96153

1. Is the library communicating through the operator panel or CLI?
No: The library is likely at fault. Restart the system to establish an operator panel or CLI session.
Yes: Continue...

2. Does the library log have error entries?
No: The site configuration, host, or network is likely at fault. Check the library and host logs for configuration activity. Run site network and connectivity tests.
Note - StreamLine error log entries indicate an unrecoverable fault. This means that the job that the host requested could not be completed, resulting in an error log entry.
Other faults, such as retry operations due to mechanism errors, are logged at a warning severity.
Yes: Continue...

3. Does the library log have error entries associated with the host fault?
No: The site configuration, host, or network is likely at fault.
Yes: The library is at fault.

Determine which library FRU is at fault.Locating the FRU problems in the logs involves:
a. Finding the first error log entry associated with the FRU and the fault.
b. Getting the activity and result information from the log entry.

To determine the current operational state of the FRU using the operator panel or CLI:
- If the current state is "online," then the fault was transient and the FRU is still functioning in the library.
- If the current state is anything else, then the FRU requires operator intervention for fault resolution.

Did a transient mechanism failure occur?
Mechanism failures are recorded in the library log. The mechanism FRU is "online" after a transient failure, but the history of the failure is recorded.
Did a permanent mechanism failure occur?
The mechanism FRU is not "online" after a permanent failure and the mechanism fails further diagnostics or attempts to make the FRU operational.

Likely resolution activities include:
-Run diagnostic tests to verify faults and/or reset the FRU.
-Update firmware (library or tape drive).

- Review symptoms and solutions that have occurred in the Knowledge Data Base for possible resolution to problem being seen.
==========================================
- Replace the FRU.
