Network Dump Manager Error Messages
Listed below are the messages that are generated by the Network
Dump Manager when errors occur while the SDLC link is being
dumped. If you must submit an SR or call your Hewlett-Packard
support contact, please copy the error
exactly as it appears on the
operator’s console
; it will make determining the cause of the
problem easier.
The messages are listed below in numerical order according to message
number. These messages are not written to $STDLIST, and they are not
logged.
DUMP ERROR 1 MESSAGE: **** DUMP ERROR 1: PATH ALREADY DELETED FROM
SYSTEM
CAUSE: The Network Dump Manager attempted to look up information
about the SDLC link driver being dumped, but was unable to locate all
of the information. This is probably because the driver had already
been shut down. A heavy system load or a hung system console can
delay the Dump Manager long enough to cause it to time out and shut
down. Note that no dump file was produced.
ACTION: If the problem continues and you need a good dump file, try
reducing the system load.
DUMP ERROR 2 MESSAGE: **** DUMP ERROR 2: LACK OF MEMORY PREVENTS
DUMPS
CAUSE: This message appears only during system boot. At boot time,
the Network Dump Manager could not obtain a block of system
memory, which is required to produce SDLC link hardware dumps. If
the system comes up, the Network Dump Manager will not work,
attempts to produce link dumps will be ignored, and no more Network
Dump Manager errors will appear.
ACTION: Take a system memory dump if the system comes up, and then
call your Hewlett-Packard support contact. If the system seems to
operate normally (except for this condition), continue to use the link
until this condition is resolved.
DUMP ERROR 3 MESSAGE: **** DUMP ERROR 3: CANNOT ACCESS INTERRUPT
SYSTEM
CAUSE: The Network Dump Manager located information about the
SDLC link hardware, but received an error when attempting to obtain
an interrupt list head from the I/O system. Note that no dump file was
produced.
ACTION: Issue the SWITCHNMLOG command (see Chapter 6 , “MPE
Commands,” of this manual) and note the name of the current NM log
file. Save the current file
and
the previous file, to prevent accidental
