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

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 10-3.
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 6-4).
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 10-3).
v If the drive diagnostic(s) pass, run the drive wrap test from the OCP.Service
> Service and select a drive. Hit the Enter key to highlight the test options
field, and hit Up/Down keys to scroll through test options. Select Wrap Test
and hit the Enter key. Then use Up/Down keys to highlight <Run> and hit
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 (refer to "Removing/Installing/Adding a Tape Drive Sled" on page
10-3).
Note: On a Half high SAS drive, run SAS wrap test. On a Full high SAS
Note: If a SCSI drive wrap test fails, run the test again, with a different
8. Using 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
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 Chapter 6,
"Using Ultrium Media," on page 6-1.

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 (visit 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 not connected to
power source, or Power Supply defect.
