<Location of the DUMP switch>
Important
•
Pressing the DUMP switch excessively shorter or longer will fail to collect
memory dump.
•
Do not use anything that easily breaks such as pencil, toothpicks, or plastic.
If you press the DUMP switch, system restarts automatically and returns to duplexed state. Wait until the
memory dump finishes completely. The memory dump is stored in /var/crash/ directory. Memory dump is not
collected depending on CPU status (e.g. CPU stall).
Tips
Memory dump process of the server may continue until the system returns to duplexed
state even after the restart. Wait for a while until duplication completes.
After executing memory dump using the DUMP switch, the server may fail to restart. In such a case, forcibly
reset the server according to
Chapter 1 (10.2 Forced Shutdown)
