VM Ware and EVA

I am upgrading the XCS code this week. Offline upgrade.

I am shutting down the Virtual servers on this EVA but the ESX server will be online since it has other virtual servers with LUNs on other EVAs.

WIll I need to unpresent the LUNs allocated from the servers I am shutting down ? on the EVA i am upgrading.

Thanks

Hi,

I wouldn't have thought so no. The ESX servers will lose their connection to the EVA for a short time whilst the controllers reboot. It shouldn't be necessary to unpresent the LUNs.

Cheers,

Re: VM Ware and EVA

You don't need to unpresent the LUNs but you must be sure that no I/O operations are done to those LUNs from the ESX server.

Unpresenting the LUNs is a way to ensure that no I/O is performed. You could also remove from the zoning configuration to ensure that.
