During datastore creation in vSphere using the Nimble vCenter plugin, I get the following error:
A general system error occurred: esxi1: CHAP setting not compatible. hba=vmhba33
In vSphere Client I went to my ESXi host then Configuration, Storage Adapters, iSCSI Software Adapter. Taking a look at vmhba33 Properties then CHAP… I see that there was a CHAP setting in there for an old Drobo system I had connected at one point.
Changing the option to Do not use CHAP resolved my issue. I’m not using CHAP on my lab setup.
