I thinks in this:

-I have 2 SCSI controllers .
-I have two disks SCSI.

-Disc one, controler 0, id 0
-this is /dev/sda0

-Disc two, controler 1, id 0
-and this is???????

how differentiate two Disk SCSI on 2 controllers different about same id?

thanks in advance!!!

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?
