What error are you getting? Credentials error? Is UI accessible from the browser? (did you enable lockdown mode?)

Firewall in between you and the esxi?

Connect  trough iDRAC,iLO,iRMC or what ever you have and take a look to the console.  Only on console you are not affected to a locked root user account but you told that vCenter also lost contact to the host and most likely the services/host crashed or become unresponsible because of lost storage for example.  So login into console and see if df h  and vim-cmd vmsvc/getallvms   returns something.

Hi Dear,

thank you, the root cause is var partition is full, how could we clear it?

On all of my ESXi Hosts  df -h  shows also my Datastores.  The error from the vim-cmd for me indicates a major malfunction which explains your al sort of your problems.  You can try to restart the services by i would just reboot the host.

Hi, hope you are doing fine


Try doing this:

cd /var  -> this will move you to the /var directory
du -h --> this will dive you a detailed list of which directory has the most size

Most likely: you will find that /var/log is full and there you might need to check to delete older logs with rm, i'd suggest using wildcards in order to bulk delete.

Warm regards

Hello Minea,

Do what nachogonzalez says and for the files that you can safely delete are the ones that ends with .1 .2 or with tar or bz extension. Those are files that are ready to be rotated so they can be safely deleted.

Also take a look at this KB: /var/log - files safe to delete
