Hello,
Our ESXi (5.5u2) hosts use a NetApp NFS storage (FAS2240) for datastores. The NetApp device is using 1 Gb connections, and we added recently 10 Gb interfaces, configured with IP addresses on another subnet.
The idea is to redeploy hosts with NFS mounts pointing to the new IP addresses on the 10 Gb network.
Unfortunately, ESXi computes an UUID for NFS datastores based on the IP address and the NFS share name, so it considers the datastores as different.
I think we can shutdown the VM, change the references to datastores in config files and register them to the redeployed hosts, or use SVMotion to move VM between datastores, but both solutions are a bit painful...
Is there another solution which would avoid downtime or SVMotion ? Is it possible to mount the NFS datastores by forcing the UUID to a specific value ?
Thanks in advance,
Christophe
