1-68 Maintenance overview
The node assessment graph log (NAG400) is generated hourly, or in
response to the NAG command, to list all nodes that are not in-service
(InSv). Field REX_INFO of log NAG400 displays the results of the latest
REX test. For LCMs, the LCM_REX_TEST result is listed first. For more
information about NAG400 logs, refer to the Log Reports Reference
Manual.
The CI level NAG command allows the craftsperson to display all
out-of-service nodes. The MAP response to the NAG command is similar to
that presented in the NAG400 log report. The command and log report are
part of the node assessment graph (NAG) feature which provides a snapshot
of nodes in the system that are out-of-service or have a REX issue. The
craftsperson can include the offline nodes in the output by entering the
command string NAG ALL. The log report function, which runs hourly, can
be turned on an off by entering the command string NAG ON or NAG OFF.
For a node to be included in the output or log report, it must be in one of the
following states: system busy (SysB), C-side busy (CBsy), in-service trouble
(ISTb), or manual busy (ManB). A node may also be included if it has
failed, aborted or did not complete the last REX test. If a node has no REX
problem, the string ATP appears in the REX column to indicate that all tests
passed.
