Collecting Memory Dump
If an error occurs, the dump file should be saved to acquire necessary information.
Dump data of ESXi host is stored in /var/core/vmkernel-zdump-MMDDYY.HH:mm.n on ESXi host.
* MMDDYY denotes the created date, and HH:mm.n denotes the created time.
* It may take certain time to create dump data file.
Consult with your sales representative before dumping the memory. Dumping the memory while the server is in
operating normally may affect the system operation.

•
A message indicating insufficient virtual memory may appear when
restarting the system due to an error. Ignore this message and proceed.
Restarting the system may result in an inability to properly dump the
data.

machine, memory dump may not be collected even when pressing the
DUMP switch. To operate the machine assuming to collect memory

•
Press the DUMP switch.
•
Run the
ftsmaint dump
