"Can't create connection." error from vmware-vdiskmanager.exe in VDDK 6.0

[jeremyb]

Working with ESXi 6.0 and VDDK 6.0. Getting "Can't create connection." error when trying to download disk. If I use VDDK 5.5.4 or 5.1.4 it works just fine. Any help would be appreciated.

After further testing here is some more detail:

Hi
can you tell us which commands you actually use ?

Would it be acceptable to disable SSL for the VDDK functions ?

Ulli

[jeremyb]

Per VDDK 6.0 release notes "SSL certificate verification is now mandatory" so I don't think you can disable SSL for VDDK 6.0 functions, but I am able to get VDDK 5.5.4 to work just fine with ESXi 6.0 with and without SSL verification enabled. Here are the commands I have ran and the results.

Also, check out my other post where I was trying to trace this issue down to being a bad SSL certificate. https://communities.vmware.com/thread/506148

Hi
I spend several hours and tried to reproduce your results.
I give up now - I tried 5.5.3, 5.5.4 and the new version 6.0 and none of those versions were able to establish a connection to a remote ESXi. - no matter if the ESXi is 5.5 or 6.0
The 5.5.4 version looked best - it even looked as if it would start to create the local vmdk - but then exited a few seconds later.
Consider yourself lucky that you at least have one working version.

I need a vmware-vdiskmanager to run the -R repairfunction and as far as I know the last version that is not broken is coming from Workstation 7.1 - that is several years old now and still has 950Gb max vmdk size.
If I remember right the last version that really could connect to an ESXi host  for me is 5.0.?
