I'm seeing this from vfp. I have checked vfp -f and all is good. vfp -d is showing all the disk. The only thing that seems to be out of the ordinary is the jbod ports both show being up with out anything connected. This is from the vfp -c. Seems odd. VA is running as single controller with a sing HBA to an N4000 3000 latest firmware applied to both the VA and N4000 as this is a newer install.<BR /><BR />Any thoughts would be great.
