Adding New Storage Adapater Software iSCSI Adapter fails on ESXI 6.5

ESXI 6.5

When I try to add a new iSCSI adapter for my new SQL Cluster servers
I highlight the Host  select configure tab then select storage adapters hit the GREEN Plus + sign select "software iSCSI adapter"
It fails with an error occurred during host configuration operation failed diagnostics report module iSCSI_vmk not loaded
I have 5 ESXI hosts and on three it works but on the two I need it does not

From the vmkernal log on both ESXI hosts it fails I get the same message.

This is Host 1

This is the first time I  added the iSCSI Adapters to these to hosts

How can it be already exists?
 

Any ideas?

Thank you

Good call

I added some hardware to host 1 the other day and after the restart I applied the open updates

Now I can add the iSCSI adapter to that host

Host 3 need to be restarted hopefully this coming weekend

Will post results.

Thank you
