There was a "kernel panic" - at least sort of.

How do I analyze the dumpfile? How can I trace what happened?

Your dump space is too small. It could not store a full dump.

sysdumpdev -e will give you an estimate of how much dump space you'll need to capture a full dump. I would suggest you provide a dump LV with at least 1.5x or 2x the estimated size.

sysdumpdev -l will show you the current dump device configuration.

You can modify the dump devices with some other flags, or via smit sysdumpdev.

A dump device is simply a logical volume of type dump. It's recommended that the primary dump device be live on local disk, preferably within rootvg.

Since you at least have the minimal dump, the best action would be (assuming you have IBM support) to open a case with IBM and upload the dump file within a snap (snap -ac) to them according to their instructions.

They will analyze the snap and dump, and (hopefully) suggest some corrective actions. Best case you stumbled upon a specific bug that has been fixed, but more than likely they will recommend you upgrade to the latest service pack for your technology level.
