Why does 1 subpath in multipathing use slice 2 and not the other??

Created: 02 Sep 2012 • Updated: 04 Sep 2012 | 2 comments
This issue has been solved. See solution.
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.

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?

Hi,

Yes, its possible that the *s2 devices have SMI type labels and the *d0 have EFI labels.

cheers
