during re-installation, you got to choose 'reinstall preserving datastores'
after successful reinstallation, you got to browse datastores using vSphere Client to register your VMs back in the inventory.
Get Esxi server into maintaince mode and reinstall
Can it be put into maintenance mode without having a working root account password?
ESXi is installed to a different partition to where your VMs are saved. You can reinstall just ESXi, they'll be an option during the install to preserve your existing VMFS datastores.
You should be able to put the host into maintenance mode through the vCenter or directly from the host with any account that has the permissions.
I have to reinstall Esxi 5.5 as the password was corrupted or reset or something. (Used it many times without issue then one day it stopped working)
Anyways I need to reinstall and keep my vm's untouched! I have found that the reinstall can be simple but I am very nervous about it deleting my VMs. I am unable to make proper backups as this password is linked to Veeam, our backup software. I have made windows server backups so the data is saved but that would be a pain to have to recreate the VMs from scratch.
I found this post:
And it mentions something about the re-partitioning of a drive...... I am confused as to how my setup is configured but if Esxi is on the same drive as the VMs I will lose the VMs?
Please and thank you!
