After enabling kdump at OS level, If REBOOT_OPTS is already set to CRASHDUMP, then it needs to be toggled as follows for Grid Infrastructure stack to pickup the change:
crsctl modify res ora.cssd -attr "REBOOT_OPTS="" -init crsctl modify res ora.cssdmonitor -attr "REBOOT_OPTS="" -init crsctl modify res ora.cssd -attr "REBOOT_OPTS=CRASHDUMP" -init crsctl modify res ora.cssdmonitor -attr "REBOOT_OPTS=CRASHDUMP" -init
If REBOOT_OPTS was set to NODUMP or "" then following commands needs be used, crsctl modify res ora.cssd -attr "REBOOT_OPTS=CRASHDUMP" -init crsctl modify res ora.cssdmonitor -attr "REBOOT_OPTS=CRASHDUMP" -init
