T062: Frame Configuration Problem
Description At boot time or run time the library physical frame
configuration is not valid.
Detection Scenarios
1. Code determines that there is greater then one control
module based on geographic address bits.
2. Code detects five frames or greater above the control
module per the geographic address bits.
3. Code detects five frames or greater below the control
module per the geographic address bits.
4. Code detects that one or more geographic address bit
patterns do not match a valid configuration.
5. The code detects/communicates with a device (I/O
Stations, power supplies, drives, blades, fan blades) that
should not exist per the detected frame count and
frame configuration.
6. Code determined frame configuration based on frame
count and geographic address bit pattern does not
match hard stops found by Y motion tests.
Root Causes
1. Greater than one control module exists in a stack of
frames wired together.
2. Five frames or greater are actually above the control
module.
3. Five frames or greater are actually below the control
module.
4. Hardware failure results in one or more invalid geo bit
patterns.
5. Hardware failure results in one or more valid but
incorrect geo bit patterns when compared to frame
count (more frames detected than actual or less frames
detected than actual).

T063: Cannot read or mismatch WWN label
Description The library logic learns the library worldwide name
(WWN) of the system by reading an internal WWN bar
code label. This is done at first boot up from a “cleared to
ship” condition in order to establish the WWN. The library
will report a problem when it cannot read a the WWN. A
different motion related problem will be reported if motion
is preventing the proper reading of the WWN.
