TS3310 Tape Library Setup and Operator Guide
Tape drive issues a TapeAlert 33 which is recognized by

the library during the continuous four second polling cycle

of drive status.

Drive has determined that there is a problem per its

internal algorithms.

Tape Drive

From the Operator Panel, select Tools → Service → Drive to
run the drive diagnostic. A blank, scratch cartridge is
required for this test.Before performing the following:
v "Removing a Drive Sled" on page 11-9
v "Replacing a Drive" on page 11-10

refer to "Diagnosing a Problem" on page 9-3 for additional

diagnostic procedures.
At boot time or run time the library detects that any door
is open when the library is correctly terminated and is in 9
of 15 valid frame configurations.
v Code detects nine specific frame configurations (out of
15 total) and the door is open.
Note: The door open bit is only valid in a properly
terminated library stack. An unterminated library stack will
appear to be equivalent to a three expansion unit stack.
Therefore, the door open bit cannot be detection of three
expansion units cannot be distinguished as a real
configuration or a mis be caused by results in an
indeterminate case where a door open cannot be
distinguished from a missing terminator.
1. Door is open. A stack of frames is not terminated
properly at run time or boot time. This includes missing
or removed cables or terminators and various electrical
hardware failures.
2. Any door is actually open and the system is in one of
the six possible configurations with three expansion
units.
3. A number of electrical hardware failures in the door
switch circuit (this includes intermittent issues).
4. Mechanical issues where door switch is not being made
even though door is closed (this includes intermittent
issues).
