Several error situations can arise during the interactive
process. The messages that may appear and possible remedial
actions are described in the following paragraphs.
5.3.3.1 Downloader Error and Procedural Messages.
Two classes of error messages are generated by the downloader
utility:
*
Messages displayed on the terminal. These relate to
operator errors during the interactive process and to
failure of entries to the download queue.
*
Messages written to the system log. These relate to
initialization failures of various types and to
secondary station response failures.
The texts for downloader utility messages are listed in Table 5-
1. Their meanings and any actions required are also described.
5.3.3.2 Downloader Error Recovery.
Certain remedial actions are recommended when an error is
encountered so that the type of problem can be determined. It
must be ascertained whether the problem was caused by a hardware
failure, an operatior error or a soft error (that is, a transient
error or one from which recovery is possible by retry).
Table 5-1 lists and explains the error messages and specifies
remedial action where appropriate. When a download operation is
aborted, the station is taken offline (no longer polled). The
only way to reactivate the station is by executing another
DOWNLOAD command.
