vSAN hosts - Reboot required

[Niyot1]

I have 6 hosts in a vSAN stretched cluster. In the summary tab of all hosts "reboot required" is indicated. Why is that?   No updates or patches have been done recently.

Hello Niyot1​,

Welcome to Communities.

This issue is not related to vSAN and thus you or a moderator should move this to the appropriate sub-forum (vSphere).

There can be a number of reasons why this message may appear on hosts:

- Staged updates.

- False positive messages as a result of vSphere replication in some older versions:

VMware Knowledge Base

- Enabling or changing IPv6 settings.

- When using Host Profiles/Auto deploy and making changes to these.

- Configuration of some VMware products e.g. NSX via SDDC/VCF workflows.

- Probably a multitude of other things I am not aware of.

Hi TheBobkin

Thanks for your response.  I am not using replication in the environment so that does not apply here.

The others aren't really applicable either, but as you mentioned it could be a host of other things. the issue does go away after a reboot.

so thats good.
