On PSOD no VMKernel Dump File is written to disk and no message is written to screen (the screen is either blank or full of dashes). I need this data to understand why the system crashes; any help as to how to fix this to write a dump file would be appreciated. Thanks.
VMKCore partition exists, is active, and is configured (esxcfg-dumppart -l).
esxcfg-advcfg -g /Misc/PsodOnCosPanic = 1.
esxcfg-advcfg -g /Misc/CosCoreFile = /var/core.
esxcfg-dumppart -C -D /vmfs/devices/disks/ = "Error running command. Unable to copy the dump partition: Couldn't find a valid VMKernel dump file. Dump partition might be uninitialized."
Hardware diagnostics (Dell) checks okay.
