Why does 1 subpath in multipathing use slice 2 and not the other??
Wondering why disk 2 show slice 2 whereas the other subpaths show only disk?
Does this mean that this disk has been formatted/labeled differently? They all should be labeled EFI.

When I attempt to initialise the LUN I get this error.
[2318]$ vxdisksetup -i storageunit2
vxedvtoc: No such device or address
I can see from this output that paths are disabled.

Having run below command 'vxdctl enable' to reconfigure DMP with new device database and I now get this output.
Does this mean that DMP now recognizes the disk as an EMI disk?
