Script File To Be Executed After Core Offline; Disabling Edac - NEC Express5800/A1040b User Manual

Script file to be executed after Core Offline

capmonitor executes all script files stored in the directory /opt/nec/capmonitor/script/cpu/offline.d upon
completion of Core Offline.
If several logical processors are made offline by a single Core Offline, the script file is executed only
once after the last processor is offlined.
Place the script /opt/nec/capmonitor/script/03kdump.sh under the directory
/opt/nec/capmonitor/script/cpu/offline.d to restart kdump as an alternative of kdump that was disabled in
3.3.4.
If you use the software that requires reboot after Core Offline (number of logical processors is reduced),
create a script file containing the necessary processes and store it under the directory
/opt/nec/capmonitor/script/cpu/offline.d.

the EDAC by creating a file /etc/modprobe.d/disable_edac.conf with the following contents:
install *_edac /bin/true
install edac_* /bin/true
After saving the file, reboot the system. After the system is rebooted, confirm the EDAC was disabled
as shown below.
# lsmod | grep edac
