VI3 Upgrade from 2.5.2

We have 2 ESX 2.5.2 servers and 2 EMC CX300 SANS, 1 production & 1 developement. The ESX developement server can see LUNS on both the Prod SAN and the Dev SAN. The production ESX can only see LUNS on the Prod SAN. The shared disks are on an EMC CX300 SAN that is formatted in VMFS with the ESX server in a storage group using RAID-5 disks. Do I need to configure the Dev ESX server not be able to see the Prod SAN if I don't won't to affect the Prod side when I upgrade the Dev server to VI3 and upgrade the VMFS?

Thanks,

Jonathan

If I followed this correctly, then it doesn't matter if the dev server can see the prod VMFS volumes.

You can still read the VMFS2 volumes.

Yes, we just didn't want the upgrade of the Dev server to mess up the Luns on the Production side since it can see them.

To be safe, just prevent the dev server from seeing the prod Luns during the upgrade and then allow visability afterwards.

This way, there's no way of making a mistake and upgrading to VMFS3.
