6.3.2 Specifying system files
Set HA Monitor in system files. Use the monsetup command to set the HA Monitor to automatically start and stop.
- Organization of this subsection
(1) If the OS is RHEL7 or a later version
HA Monitor provides the Unit settings file (/usr/lib/systemd/system/HAmon-powercontrol.service). Execute the systemctl command of the OS to enable the service.
Use the following method to enable the service:
# systemctl enable HAmon-powercontrol.service
The following shows the contents of the Unit settings file:
[Unit] Description=HA Monitor(power control) After= sysinit.target network.target sshd.service jp1_base.service HABooster.service ltd.service haconnd.service [Service] Type=oneshot RemainAfterExit=yes ExecStart=/bin/sh -c '/opt/hitachi/HAmon/bin/HApwon >/dev/null 2>&1' ExecStop=/bin/sh -c '/opt/hitachi/HAmon/bin/HApwoff >/dev/null 2>&1' [Install] WantedBy=multi-user.target
To change the automatic start and stop sequence of HA Monitor, modify the values specified for the After entry under the [Unit] section in the Unit settings file. For details about the Unit settings file, see the documentation for systemd of the OS.
- Notes
-
-
You can change only the values for the After entry from the default settings. Do not change or delete other default settings provided since installation.
-
Although you can add services to the After entry, you must not change or delete the other default settings provided since installation.
-
If you add options, adequately make prior consideration and verification. If you specify incorrect settings, such as those causing service dependencies to loop, the OS might be unable to start.
-
The Unit settings file under /usr/lib/systemd/system is overwritten when an overwrite installation of HA Monitor is performed. Therefore, if you want to edit the Unit settings file, copy HAmon-powercontrol.service under /usr/lib/systemd/system to /etc/systemd/system, and then edit the file at the copy destination.
-
(2) If the OS is RHEL6
HA Monitor provides the /etc/rc.d/init.d/HAmon script. Register the script by executing the chkconfig command of the OS.
Use the following method to register the script:
# /sbin/chkconfig --add HAmon
To change the automatic start and termination sequence of HA Monitor, modify the chkconfig control statement at the beginning of the /etc/rc.d/init.d/HAmon file. For details about the control statement, see Help for the chkconfig command of the OS.
Note that the /etc/rc.d/init.d/HAmon file is overwritten when an overwrite installation of HA Monitor is performed. Therefore, if you modified the /etc/rc.d/init.d/HAmon file, back up the /etc/rc.d/init.d/HAmon file before you perform an overwrite installation of HA Monitor. After an overwrite installation of HA Monitor is performed, modify the /etc/rc.d/init.d/HAmon file again based on the backup file.
