3. Try reseating the drive sled.
Note: The drive sled is hot-pluggable so it is not necessary to power off the library. See
“Removing/Installing/Adding a Tape Drive Sled” on page 181.
4. Cycle power to the library.
5. If air does not flow from the drive sled cooling fan grill on the rear of the library, replace the drive
sled CRU. Several library error codes also point to cooling problems. See “Removing/Installing/
Adding a Tape Drive Sled” on page 181.
6. If the drive is experiencing permanent or temporary errors or if the amber Clean LED is lit on the
front panel of the library, select Clean Drive from the Operator Control Panel Service Menu (Service >
Service > Clean Drive) and clean the drive. Use only an approved cleaning cartridge (see “Cleaning
Cartridge” on page 142).
7. 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.
v If the drive test fails, replace the drive sled CRU (refer to “Removing/Installing/Adding a Tape
Drive Sled” on page 181).
8. 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 “Using Ultrium Media” on page 139.
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), then.
2. Observe the LED on the Library Controller Card.
v LED On solid - LCC failed or in a hang condition.
v LED Off - LCC not fully inserted, or LCC failed, or library not connected to power source, or
Power Supply defect.
v LED flashing (1 flash per second) - normal operation
v LED flashing (slower than once per second) - normal operation
v LED flashing (faster than once per second) - LCC failed
3. With library power OFF, loosen the two thumb screws which secure the controller card to the library
enclosure and slide it out.
v Inspect the card for any broken components or other anomalies.
v If the card appears to have no abnormalities, reseat the card back in the library, tighten the thumb
screws, and turn library power ON.
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 see “Isolating Web User Interface Problems” on page 159 before
replacing any CRUs.
5. If a control card error code has been obtained and reseating, power cycling, and updating the library
firmware did not fix the problem, the controller card CRU is the most likely failing CRU (refer to
“Replacing a Library Controller Card” on page 187).
6. If the error code indicates an accessor type error (slider, elevator, sled, etc.), release and remove both
magazines (see “Control: Magazine” on page 91, “Manage Library: Release Magazine” on page 115, or
“Releasing the Magazines Manually” on page 175) and observe the accessor path for any obvious
obstruction or problems. Resolve any observed problem if possible. Execute a Library System Test. See
“Service Library: Perform Diagnostics” on page 132 for the web or “Service: Run Tests” on page 103
for the OCP If the problem is persistent, contact Dell technical support.
7. If the library is taking an extended amount of time in recovery to complete initialization, perform an
inventory, or executing a cartridge movement within the library, and, after finding the magazine cell
fiducials to be present with no visible damage and correctly installed, suspect the sensor/emitter on
