Best practice for hosts when doing SAN maintnanence

[RobWindham]

I need to take my SAN offline for a hardware replacement. I am wondering what I should be doing with my hosts during the maintenance window. If I power down the VMs and put the hosts in maintenance mode, should that be enough? Or should I shut down the hosts completely?

Hi,

It happened to me and I preferred to turn off the Esxi hosts

Hi,

I added a link for your info

Are you using vsan,  I just want to make sure, because if your using an external san you may want to shutdown the hosts as well. Its crtical if your booting from said san, but also if your redirecting logs and the scratch partition to the SAN. I doubt your using vsan, as the storage is part of the hosts and not external so that link probably does not apply.

No, I am not using Vsan. This is an external SAN I am talking about. Sounds like shutting down the hosts is definitely the way to go. Thank you
