ZAPI Panic Examples:

This first example is forcing a panic of all nodes via the cluster server (cserver).

Force an error condition that forces the trigger to be executed:

robin-ptc% ./dt if=/var/tmp/dt.data bs=512 count=1 position=0 \
                pattern=0xdeadface flags=direct \
                trigger=zapipanic ontap_cserver=rtmiller-vsim3-d2.sim.rtp.netapp.com
Then verify all nodes of the cluster have rebooted with dump enabled (panic).

This second example forces a panic on specified cluster nodes:

robin-ptc% ./dt if=/var/tmp/dt.data bs=512 count=1 position=0 \
                pattern=0xdeadface flags=direct trigger=zapipanic \
                ontap_nodes=rtmiller-vsim3.sim.rtp.netapp.com,rtmiller-vsim4.sim.rtp.netapp.com
