ESXi Advanced Settings - XCOPY Failure

[barnette08]

When trying to set XCOPY to 16MB I get an error.  I have tried quotes and no quotes and all other Advanced Settings seem to work fine.  Also I noticed that this cmdlet is considered onsolete and the Set-AdvancedSetting cmdlet took it's place, but can't get it to work either.

Command:

Set-VMHostAdvancedConfiguration -VMHost host01 -Name DataMover.MaxHWTransferSize -Value "16384"

Error:

Set-VMHostAdvancedConfiguration : 11/16/2017 1:12:50 PM Set-VMHostAdvancedConfiguration         A specified parameter was not correct:

Did you try leaving out the quotes?

Now it is perhaps considered a string

Yep, the integer fails with the same error message as well.  I even tried it with pipelines, but Set-VMHostAdvancedConfiguration does not take pipelines apparently.  I could always try with the non-obsolete cmdlet I guess but didn't iron out that syntax.

This seems to work for me

Get-AdvancedSetting -Entity host01 -Name DataMover.MaxHWTransferSize |

Set-AdvancedSetting -Value 16384 -Confirm:$false

Thanks LucD​, I'm going to go back and convert the others back to this cmdlet as well!
