  • 1.  ESXi reboot required right after update or later

    Posted Jul 25, 2023 06:30 PM

    Dear all !
    If I update ESXi host via "esxcli software vib update -d..." is it required to do the reboot (if reboot is required) right away or can the reboot be postponed for e.g. a few hours ?

    Many thx for your knowledge and thoughts !

    Kind regards

    No, a reboot is required right after the command and confirmation from ESXi that a reboot is needed.

    Many thx !
    However in ESXi Shell there was no info/message that reboot is required; I updated various ESXi hosts to 7.0 U3n today using "VMware-ESXi-7.0U3n-21930508-depot.zip" and I asked myself if I can update at e.g. noon but reboot ESXi hosts later in the evening.

     

    Thx for clarification !

    Kind regards

    Please find below the two documents that are used to update or determine if host to be rebooted or not depends on the type of installation:

    Many thx for your reply.

    Of course I did this check before and as there are many vib packages involved in the depot some of them are installable online (do not require reboot) and some are not (require reboot)...means a mixture.

    My question is - if a reboot is required - if this reboot needs to take place right away or can be done later (as with Windows Updates).As said the update process did not show any "please reboot" message at the end.

    Kind regards

    Please check the output of the following command and see if reboot is really required:

    vim-cmd hostsvc/hostsummary| grep -i reboot

    Check for the parameter "rebootRequired" is true or false.

    It is advisable to reboot host after update as some changes may take place after reboot. If it is not asking for the reboot instantly, you may reboot it later (during downtime window). In that case changes will take effect after the reboot.
