FC HBA rescan - in maintanace mode or not?

Hello,

I have problem with HBA rescan this week. When I perform it ESX went to restart. Do you use rescan in maintanance mode or on live ESX server.

Our support suggest to us go to maintanace mode, but in documentation VMware talking about rescan without maintanance mode.

Thank you for your experiences!!

Hi roc.ker,

we rescan HBA's most of the time on live ESX servers wich also running production on it..

we don't put them special in maintenance mode for this.

so we use it a lot and have almost never problems with it..

we had some situations when the esx host was disconnected and connected again from virtual center but this gave no impact on the virtual machines.. they just keep running

Thanks for reply. We had issues with disconecting ESX servers from VCMS on ESX 3.0.1 too. I think that this issue was solved in next version.

We are running 3.5.0 now and we don´t have problems with this.

yeah there are a lot of improvements with esx 3.5 if you compare it to 3.0
