Adding New Storage Adapater Software iSCSI Adapter fails

[insearchof]

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

Any ideas?

Thank you

Might want to check vmkwarning.log first on the offending ESXi hosts to see why that module might not have loaded.

try

(get-log -vmhost (get-vmhost 10.2.8.10) vmkwarning).entries

ing this command line but it fails  

Can I view the logs using this?

Do you have a better method or command line that will work?

[daphnissov]

You need ssh access. It's a file log, not a host log stream.

I just exported my bundle

went to var\log and I do not see a current vmkwarning log

I then went to var\run\log folder and found the archived  the date on the file is 3/4/2018 that is the last entry in vmkwarning

Any other ideas?

Thanks

Check vmkernel.log around that time. It may not be included in vmkwarning.

daphnissov,

Ok from the powershell cli I was able to recreate the vmkernal log

Here is what I found

This is Host 1

This is the first time add the iSCSI Adapters to these to hosts?

Any ideas?

[insearchof]

This is still happening any ideas???

[daphnissov]

Have you tried a simple reboot of the offending hosts?

[Wolken]

Are these 5 ESXi hosts in the same cluster? Maybe you have to restart vCenter?

[Finikiez]

Can you show a screenshot with existing storage adapters on Host 1 and Host 3?

[insearchof]

Thanks Guys

I had a power outage and I restarted my HOST and then I was able to add the iSCSI Adapter.

Do not understand why that had to be done

But glad that fixed it.

You can lock the as fixed

Thank you
