includes the unit number if the REX test action is unit-specific (BSY unit,
RTS unit, TST unit, synchronization). The log does not include the unit
number if the REX test action does not affect the node (SWACT, BSY both
units). The log additional data consists of a card list and a mnemonic of the
failed diagnostic.
The QUERYPM, QUERYPM FLT, TST REX QUERY, and TST REXCOV
QUERY commands contain information about the last REX test. Manually
and system-initiated REX tests store and display a new date, time, and status
(passed or failed) in the REX test maintenance record. Passed means the
REX test completed without errors. Failed means the REX test did not
complete because of an error. This information is available through the
QUERY PM and TST REX QUERY commands. If the REX test fails, you
perform one of the following tests to return the XPM to service from ISTb:
manual RTX
manual REX
automated REX
The system stores a REX test maintenance record for each XPM that
contains the following information:
REX test scheduler, if the XPM is in the system
date, time, and result (passed or failed) of the last REX test
failure reason, diagnostics failures, and a list of defective cards (if
applicable), if the last REX test failed
date and time of prior failed REX test
date and time of first passed REX test following earlier failure
