The Fujitsu sadump mechanism provides a fallback dump capture when kdump is unable to complete successfully. You can manually invoke sadump from the system Management Board (MMB) interface. By using MMB, configure kdump such as for an Intel 64 or AMD64 server and then proceed to enable sadump.
Procedure
Add or edit the following lines in the
/etc/sysctl.conffile to ensure thatkdumpstarts as expected forsadump:kernel.panic=0 kernel.unknown_nmi_panic=1警告In particular, ensure that after
kdump, the system does not reboot. If the system reboots afterkdumphas failed to save thevmcorefile, then it is not possible to invoke thesadump.Set the
failure_actionparameter in/etc/kdump.confappropriately ashaltorshell.failure_action shellSee the FUJITSU Server PRIMEQUEST 2000 Series Installation Manual for more information.
