I am trying to get the core dump files for VMware support but I am having a hard time. I am trying to follow this KB.

http://kb.vmware.com/selfservice/search.do?cmd=displayKC&externalId=1002769

I ran this
esxcfg-dumppart –t

I got this
naa.600508b100103956595531524f330100:7
The best I can figure the above is this datastore “esx02-local01” or "51b1050b-27757685-6aa9-1cc1de20bdaa"

I changed directory to here.
cd /vmfs/volumes/51b1050b-27757685-6aa9-1cc1de20bdaa/

Then I ran this
esxcfg-dumppart --copy --devname "/vmfs/devices/disks/naa.600508b100103956595531524f330100:7" --zdumpname /vmfs/volumes/esx02-local01/filename.1

And I got this.
Error running command. Unable to copy the dump partition: Couldn't find a valid VMKernel dump file. Dump partition might be uninitialized.

Background Esxi 5.5 U1 HP Build. DL380 G6

Any help would be most appreciated.

Did you try the command with another destination datastore, local or on NFS or something (if one available)?

e.g:

esxcfg-dumppart --copy --devname "/vmfs/devices/disks/naa.600508b100103956595531524f330100:7" --zdumpname /vmfs/volumes/esx02-local02/filename.1

That is a local datastore.

Yes, I know, but I just wanted to know if the command works if you use another datastore than the one you used in your command...

I tried this I got the same message.

esxcfg-dumppart --copy --devname "/vmfs/devices/disks/naa.600508b100103956595531524f330100:7" --zdumpname /vmfs/volumes/esx02-local01/dump.log

I see no difference in your command? You should check if there's enough room on the datastore you want the log to be saved to, do you have only 1 datastore? You can't save to another one? I'm not saying it's the solution but we need to rule out everything.

This one was esx02-local01 the first one was esx02-local02
One was 01 the other is 02
There is hundreds of GB on 02 and 30 GB on 01

Ok, thanks ... Did the ESXi server ever have a Purple Screen before?

Is this a fresh install or an upgrade?

The reason I'm asking is because the coredump partition for new installations of ESXi 5.5 and later is 2.5GB, as it was previous 100mb...

So if it's an upgrade it might be an issue with the coredump partition not being big enough...

The one that has been crashing the most is a clean install.
