Dear friends,

 

I did some searches here looking for tips about "multipath.conf" and i couldn't reach a definitive answer.

 

Can someone say me if exemple below is right for my environment (Oracle Linux 6.4 x Hitachi VSP x Oracle 11g release2).

 

Thanks for any answer.

      devnode "hd[a-z][[0-9]*]"

      devnode "cciss!c[0-9]d[0-9]*[p[0-9]*]"

      }
