Replacing a LANMON Without a Cold Load
As of the G06.21 RVU, a new LANMON can be installed without doing a cold load if
your system has the LANMON SPR’s requisites (see the LANMON SPR associated
with your RVU for these requisites). If you do not have these requisites, you must
install them and cold load the system.
Assuming the primary LANMAN is running in CPU 0, perform the following steps to
replace a LANMON in all CPUs:
1. Follow the installation instructions described in the LANMON SPR associated with
your RVU, including the DSM/SCM Build/Apply and ZPHIRNM Rename steps.
However, do not cold load the system.
2. Use the SCF ABORT MON command to ABORT and start the LANMONs in
CPUs 02 through 15, sequentially, as follows:
a. Stop the LANMON in CPU 02.
b. Start the LANMON in CPU 02. Verify the LANMON has started.
c. Ensure that SAC, PIF, and LIF access is gained on CPU 02 before stopping
the next LANMON.
d. Repeat substeps a, b, and c for each remaining CPU (that is, CPU 03 through
CPU 15).
ALTER PROC $ZZKRN.#ZZLAN, stopmode sysmsg
ABORT PROC $ZPM
START PROC $ZZKRN.#ZZLAN
ABORT PROC $ZZKRN.#ZZLAN
Note. When you restart the LANMON, the corrected LANMON object file that you installed
in the SYSnn subvolume will be used to start the LANMON process in that CPU.
