Error messages for Data Mover
While using the system, various messages can appear indicating successful or
unsuccessful command execution. Error messages can appear when there is a
fault in a command syntax or a fault with the system. Normally, system messages
are reported to the log files. Always check the system log (sys_log), which is
produced by server_log, and the command error log (cmd_log.err) for message
information. In some cases when a problem occurs, no message appears. Instead,
system actions occur, which in turn, might indicate a problem. Table 12 on
page 105 lists two examples that might occur with Data Movers or blades.
Error messages indicating a problem with a Data Mover or blade might also appear
in the system log. Therefore, when troubleshooting, periodically check the log for
the presence of certain error messages. These error messages appear only in the
system log and do not appear on screen during an active session.
