Isolating A Library Controller Card Vs. Accessor Enclosure Problem - Overland Storage NEO 200S User Manual

NEO 200s/400s User Guide
6. Run the Library Verify Diagnostic which includes a drive performance Read/Write
test. Be sure to use a known good scratch or blank data cartridge.
If the drive test fails, replace the drive sled.
7. If the drive diagnostics pass, run the drive wrap test from the Operator Control
Panel:
a. Press Service > Service and select a drive.
b. Press SELECT to highlight the test options field, and press UP and DOWN to
c. Highlight Run and press SELECT.
d. When prompted, connect the Wrap Test Adapter and select OK.
e. If the wrap test fails, verify that you are using a wrap tool and not a terminator. If
8. Using the host interface test tool, ITDT, run the Scan functions to verify that the host
application interface (SAS or Fibre Channel) can detect the drive (LUN 0) and the
library (LUN 1). To further test the interface communication path, run the Test
Device function (t), if available, after selecting the drive. This function will write/read
data across the interface as well as sending a command to the drive to run the
internal performance Read/Write test.
9. If the host tool, ITDT, cannot detect the drive or library, look for problems with the
host interface cabling, the HBA, the device driver, or the backup application software.
10. If the drive passes all the tests, inspect the media to ensure the media is compatible
with the drive and not causing drive errors. Refer to

Isolating a Library Controller Card vs. Accessor Enclosure Problem

1. If possible, ensure that the library firmware is at the latest level, check the current
library firmware level using the Operator Control Panel (Monitor > Library > Identity
> Version) or the Web User Interface (Monitor Library > Library Identity).
2. Observe the Library Controller Card LED.
• LED On (solid) – LCC failed or in a hang condition.
• LED Off – LCC not fully inserted, or LCC failed, or library not connected to power
• LED flashing (1 flash per second) – normal operation.
• LED flashing slow (slower than once per second) – normal operation.
• LED flashing fast (faster than once per second) – LCC failed.
3. With library power OFF, loosen the two thumbscrews which secure the controller
card to the library enclosure and slide it out.
• Inspect the card for any broken components or other anomalies.
• If the card appears to have no abnormalities, reseat the card back in the library,
4. If both the Operator Control Panel and Web User Interfaces are inoperable or
frozen and the latest firmware has been installed, the controller card CRU
electronics is the most likely failure. If only the Web User Interface has failed, please
