Isolating A Library Controller Card Versus Accessor Enclosure Problem - IBM TS3100 Setup, Operator, And Service Manual

v If the drive test fails, replace the drive sled CRU (refer to "Removing/installing/adding a tape
drive sled" on page 223).
v If the drive diagnostic tests pass, run the drive wrap test from the OCP.Service > Service and
select a drive. Press the Enter key to highlight the test options field, and press Up/Down keys to
scroll through test options. Select Wrap Test and press the Enter key. Then, use Up/Down keys to
highlight <Run> and press the Enter key. When prompted, connect the Wrap Test adapter and
select <OK>.. If the wrap test fails, verify that you are using a wrap tool and not a terminator. If
you are using the correct wrap tool, replace the drive sled CRU (see "Removing/installing/adding
a tape drive sled" on page 223).
Note: On a Half Height SAS drive, run SAS wrap test. On a Full Height SAS drive, run SAS Wrap
A and then run SAS Wrap B.
Note: If a SCSI drive wrap test fails, run the test again, with a different SCSI terminator before
exchanging the drive sled.
8. With the host interface test tool, ITDT, run the Scan function (s) to verify that the host application
interface (SCSI, 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 the
drive is selected. This function writes/reads data across the interface and also sends 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 that the media is compatible with the
drive and not causing drive errors. See "Ultrium media" on page 163.

Isolating a library controller card versus accessor enclosure problem

Procedure
1. If possible, ensure that the library firmware is at the latest level, check the current library firmware
level with the Operator Control Panel (Monitor > Library > Identity > Version) or the Web User
Interface (Monitor Library > Library Identity), then (see http://www.ibm.com/storage/).
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 that is not connected to power source, or
Power Supply defect.
v LED flashing (one 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 that 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 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 is installed, the controller card CRU electronics is the most likely failure. If only the Web
User Interface failed, see "Isolating Web User Interface problems" on page 198 before any CRUs are
replaced.
5. If a control card error code was obtained and reseating, power cycling, and updating the library
firmware did not fix the problem, the controller card CRU is the most likely culprit (see "Replacing a
library controller card" on page 231).
6. If the error code indicates an accessor type error (slider, elevator, sled), release and remove both
magazines (see "Control: Magazine" on page 97, "Manage Library: Release Magazine" on page 122, or
