I am about to embark on a quite large host upgrade. We have 60-80 Vlan configurations. Typically I just run a script from the .csv file and it will import the vlans and switches. However , I still have to configure the physical adapters , iscsi etc. This is simple, but looking to streamline my process since I will be working with 300+ host. Just trying to work smarter. I have tried powershell scripts but doesnt seem to work. Is there a utility or application / fling that will back up my network config, and that I can push back out once my re-install / upgrade is complete on that host? Eager to hear the solutions.
If you're doing an upgrade, it won't blow away your vswitches, port groups, or any other networking configuration. If you're doing a wipe-and-reload then that will, but are really doing this on 300+ ESXi hosts??
Yep:) Not all at once. Have a lot of 5.1 hosts that need to goto 6.0u3 then eventually to 6.5 - The upgrade will be more present for the 6.0-6.5 but for now the wipe is the best way.
And you're not licensed for vDS on these where you could just backup and restore the entire vDS?
yea , we are not using any virtual distributed switches would be nice
Are these hosts licensed with something other than ESXi free?
Yes Enterprise+ - But what I ended up doing was using the script which copies the same config over from any host. So , I manually updated one. Then ran the script on another one- It works and only required that I manually put the IP's in for vmotion and iscsi.=== from there I made a workflo for vrealize to run the script automatically when a new SSL cert is pushed in the new cluster. So after upgrading - I manually reconnect host and accept the new cert. Boom- script runs- config is pushed -
start to finish is about 25 min on each host. better than 1.5 hours
I'm also looking for this solution.
I have problem that after reboot physical NIC are not connected to vSwitch (actually 2 NIC's to 2 vSwitch)
I can't find the solution for this problem (https://communities.vmware.com/thread/607658)
I would like to solve it but in between it could be nice that I fix this with re-installing whole network.
Now I have to do it manualy via putty
(so after reboot i re-install network)
Is it posible?
Sure, I'm interesting for both solutions.
Thank you for your answers.
