Typically, disks are assigned in alphabetical order. The fist disk recognized on the 1st controller recognized will be sda, the next sdb and so on with the next controller.

so:

-Disc one, controler 0, id 0
-this is /dev/sda

-Disc one, controler 0, id 1
-this is /dev/sdb

-Disc two, controler 1, id 0
-this is /dev/sdc


this is right?

Yes. Was that a typo in your last post? You have two disks on controller 0?

NOT typo.

in first case:
-Disc one, controler 0, id 0
-this is /dev/sda


-Disc two, controler 1, id 0
--this is /dev/sdb


*
in second case:
-Disc one, controler 0, id 0
-this is /dev/sda

-Disc one, controler 0, id 1
-this is /dev/sdb

-Disc two, controler 1, id 0
-this is /dev/sdc


this is right?

thanks in advance!!!

Yes but to be sure I need further verification?
You have a single hard drive on controller 0 that can be assigned multiple device IDs? What is the make / model number?
