How to modify the esx.conf file on a second hard drive (not the boot disk)

[conna07]

Hello all,

Hopefully you guys can help me.  I was messing around with the esx.conf file (/etc/vmware/esx.conf) on my lab (small PC) running ESXi 6.5 and now Hypervisor does not boot at all. I know exactly which line I have to revert back to original. My lab PC is a single SSD hard drive, nothing fancy.

Luckily, I have an external hard drive with ESXi 6.5 (configured and operational) and I'm able to boot from that external hard drive and use the CLI.  How can I access the SSD hard drive, navigate to the esx.conf (of the SSD HD) and vi the file that I changed earlier?  I know how to use vi, question is how do I get to that esx.conf file that is corrupted?

Does that make sense?  I really don't want to blow the entire lab ESXi away and start again; it took me sometime to install and get all the VMs configured correctly.

Thanks in advance for the assistance.

Booting from the external drive should mount the the local drive allowing you to access them under /dev/disks/.

Are you booting in Linux? You can use "fdisk" to list SSD disk's partitions and then mount them using the "mount" command.
