When adding a new ESXi to vCenter the following message appears: "License not available to perform the operation."
We had to reset BIOS Battery while Rack and Stack, because Server did not boot up. So time is not set correct. Logfiles had a time of 2001-01-01.
Set correct Time in BIOS and boot Server up. Then you will be able to import ESXi using Evaluation License.
Occasionally I spend some time in discussions with customers and co-workers about the need to use Jumbo frames or not.
In my opinion, you don't need Jumbo frames in a 10G+ world.
And here is why:
If you have a Greenfield installation you can consider using Jumbos.
But in a Brownfield (which is about 90%+) stay on 1500.
IO Filters marked offline in a vSAN cluster. One of the reasons can be the missing Self Signed SSL certificate in /etc/vmware/ssl/castore.pem Before making any changes in the system , please validate if the customer is using the third party certificates Configuring Custom Certificates on ESXi hosts to authenticate vSAN hosts https://kb.vmware.com/s/article/56441
You may find the below instances showing that SSL certs are not being verified for the hosts in the IOfiltervpd logs (ESXi : /var/log/iofiltervpd.log )
iofiltervpd: IOFVPSSL_VerifySSLCertificate:239:Client certificate can’t be verified
The newly added Host may show the IOfilters providers as “online” You may find that the certificates located at /etc/vmware/ssl/castore.pem, have missing the “Self Signed Certificate” for the host with IOfilters offline Following is Self signed certificate which must be part of the /etc/vmware/ssl/castore.pem file
You may follow the below steps :
The providers should show as “online” in vCenter > Configure > Storage Providers

VMworld 2019 closed last week. As every year it was a pleasure to join. Extremely valuable Sessions, good networking and indeed cool parties.
William Lam curates a list of sessions with Streams and PDF (if): https://github.com/lamw/vmworld2019-session-urls
Many Sessions were around Project Pacific and VMware Tanzu. I try to keep you posted in the next weeks on those topics. Also many deep dives took place and they were worth it.
