4.1.5 Dump collection

・ftsmaint dump path
This command generates a dump of the CPU module specified in the path argument.
The dumps for the ESXi host are saved in /var/core/vmkernel-zdump-MMDDYY.HH:mm.n.
* MMDDYY denotes the created date, and HH:mm.n denotes the created time.
* It may take certain time to create dump data file.
Important Do not use this feature to retain a faulty or degraded device in service. It may be
useful if the MTBF for a device has been degraded by testing or a configuration
error.
Important If you run this command, the specified CPU module is made offline automatically,
and duplication of system is canceled. (The specified CPU is made online
automatically upon completion of command.)
Note The system must be duplexed before running this command.
Tips The dump files cannot be deleted automatically. Check the /var/core directory size
periodically in order not to run out of the capacity. The size of a dump file is approximately
100 MB.
