FMC Down after Upgrade attempt

keithcclark71 — Tue, 21 Jun 2022 13:35:09 GMT

I have TAC opened on FMC that is not responsive any longer after a co worker intervened during an upgrade patch attempt. It appears that TAC is pretty busy as I can't seem to get the proper assistance here. Since this FMC is virtual I am thinking of just blowing away the VM completely the rebuilding it and then re-registering the FMC with the smart portal. Once I am done with this part I was hoping it would just be a matter of restoring from the latest .tar backup I have. Is my thinking here on the right course? WIll I need to manually redeploy once I do a restore or change any settings that the restore might not bring over (SSL Certificates , anyconnect VPN settings etc) I really need to get this running again

Since you mentioned VM, have you taken a snapshop before upgrading taking place ?

what is the version of FMC running, what version you trying to upgrade ?

Do you have any Logs ? or errors which was failed.

you can do that offline another VM and restore the config test it.

That's what I would do. VMware snapshot first, and if you don't have one of those storage snapshot, or restore from backup. Last resort would be a fresh install and DB restore. The fresh install and DB restore is probably best practice, but it's also going to take the most effort if you have to do any of the certificates and don't have access to the old ones to import.
