Our company just moved to a new building so I had to shutdown our NetApp and VMware Infrastructure. When I was shutting down the NetApp (FAS2240), I issued CF disable command. When I brought the NetApp back up, I forgot to issue CF enable, and just left. I then started getting phone calls when the other engineers started to turn ON the ESXi hosts saying all the VMs say they are inaccessible. The host configuration, under storage showed only local storage, and could not detect the NetApp NFS volumes. I could not confirm this myself, because I was not there.
When I cam back, I issued the CF enable command, and so far, things are looking OK, and I was able to boot up several VMs, and am able to see NetApp volumes in VSphere.
Is it possible that the "CF enable" command is necessary before turning ON the VMs? If so, why?
