Go through the creation of an ESXi host profile based on a reference host. Learn how to create a host profile in your virtual environment.
- [Voiceover] Alright, so let's go into my environment and actually extract a host profile from a host. The very first thing I want you to do is look at the configuration of the host in question. Make sure it's a really good candidate to be a reference host. So, we can go to summary and take a look at this host. We can se it's running ESXI 6.5. Make sure that's at least the version you wanna run, right? We can see that the logical processors, the NiCs, those are important things that we need to make sure are similar, but we have to make sure that the number of NiCs, more than processors, processors are not such a huge deal in the configuration.
But network interface cards are, because I have two configurations there. If I apply this profile to a host that only has one network interface card; guess what? That's a problem. 'Cause it'll never be able to attain that level of configuration. Another thing I need to look at is my configuration and not just for storage adapters. It jumped the storage adapters, so I'm gonna go right into that, obviously. We need to make sure that the storage adapters are correct. If I have a HBA card in place; make sure that the hosts that are gonna attach to this profile also have an HBA card.
We also have to make sure on our networking side, make sure that we have enough uplinks. Don't worry about the V switch configuration, because that'll be recreated through our remediation processor making sure that it works. We need to make sure that we have enough physical adapters to match what we're gonna configure on the other side of things. So, make sure that there's enough physical adapters on your target hosts to match the number of configured physical adapters on our reference host.
So, that they're the same. So, we don't bonk out of our remediation, because there's not enough physical adapters to make the configuration changes needed. Now, once we've made sure that all our hardware lines up and it's possible to have the same configuration on a target host as it is on a reference host, we need to extract the actual profile. Now, the way that most people do this is the run to "Policies and Profiles" right here listed "Policies and Profiles". They go to this portion, they click on "Yes", and then they go to "Host Profiles" down here on the bottom/left.
Once you're on "Host Profiles" you can click on "Extract Profile from Host". This will give you a list of hosts in your vCenter server domain, and then you simply just choose one and click "Next" to extract the host profile. Now, when you do that, you're gonna have to put up a name. I highly recommend you use a naming convention that matches a profile that you are creating. So, vCSDomainlab.
And, you can even put a description. "Oh, this was created on such-and-such a date of 2017." Something of that nature and then you would click "Finish". Now, once that's done you can see at the bottom- I'm gonna expand this out for us. You can see at the bottom that we are actually creating a profile. Now, this is gonna take some time because it's actually pulling those different configurations from different areas on the host, and it's putting it in a profile that other hosts, our target host are gonna be checked against. So, it's gonna take a little time to actually create.
And, as you can see, we've finished our host profile. It was that simple. We now have the host profile listed up here as vCSDomain. Now, that's not the only way to create a host profile. A lot of you guys are probably surprised by that. If you right click on a host, and you go down to "Host Profiles"; I could have extracted directly from the host with a right click. Now, that's much easier and quicker than going to the Host Profile Management area, but just a simple shortcut to help you along the way.
