21.6 Setting up kdump

Set up the following on all nodes when using the kdump (recommended).

1. Set up the kdump parameter.

   In a two-node configuration, to power off the cluster node after the memory dump is output, set the following parameters in the /etc/kdump.conf.

   For details on the setup procedure of the kdump, refer to the OS manual.

   Parameter	Value	Remarks: meaning of (parameter)
   kdump_post	/opt/SMAW/SMAWsf/bin/poff.sh	The power-off script (poff.sh) is executed after the memory dump output ends.
   default	poweroff	The power is turned off when the memory dump output fails.

2. Check the kdump.

   Check if the kdump server function is enabled. If not, enable the kdump.

   • Check the availability of the kdump with the systemctl(1) command.

     Example) The kdump is disabled if the state is as follows.

     # /usr/bin/systemctl list-unit-files --type=service | grep  kdump.service
     kdump.service                               disabled

   • If the kdump is enabled, restart the kdump with the systemctl(1) command.

     # /usr/bin/systemctl restart kdump.service

   • If the kdump is disabled, enable it with the systemctl(1) command, and then start the kdump.

     # /usr/bin/systemctl enable kdump.service
     # /usr/bin/systemctl start kdump.service

Note

After uninstalling PRIMECLUSTER, make sure to change the kdump settings back to the state before installing PRIMECLUSTER.
