Re: [dm-devel] Too many paths from multipath?

Ok that seems right, but on my case I have 4connections per HBA total of 8per Lun

The info I got regarding zoning is that each HBA is connected/zoned to only one Storage controller
So that would make 2connections per Lun

What I suspect is that the Fabric here is made of 4switchs and that makes 4x plus. The SAN people just configured it with a generic "big" fabric zoning just one connection. but Linux shoes 4. could this be the reason?


The number of paths shown on multipath -ll depends on how your zoning is done. The easiest way is to check with your SAN administrator on how the zoning is done and on how many switches and that will explain the 8 paths you're seeing.
