If an error is detected with any part of the process of reading the program
update file from the disk or tape and applying the program update to
memory, a hardware error 409 will be generated. This error will invoke a
MAJOR alarm and
Emergency Transfer
on a system with simplex SPE. It
will initiate an SPE interchange followed by a MINOR alarm on a system
with duplicated SPEs. When this error occurs, the copies of the program
update files on the disk and tape are invalidated so that those files no
longer appear when a
list configuration software
command is entered
from the System Access terminal.
To clear this alarm, first correct any other tape and disk alarms. Then
restore the two copies of the program update files on the disk and tapes
and apply those upgrades using ‘‘Software updates’’
in Chapter 6.
v. Error type 3841 is used to record miscellaneous data when an
out-of-service condition occurs. See the
MSS Error Actions
table at the
end of the section on TAPE.
