Sorry, its different question. It is for soalris and other one for linux. Sorry I have tried format command here.

It would help if you provide more information, like the format command output.

Also, how are the external disks connected ? Say, if you have both internal and external SCSI disks, there is no automatic way to distinguish between them.

But that also depends on your hardware. Most of the Sun SPARC based hardware I have dealt with specifically maps the internal drives to c0. On an E250, they are c0t0, c0t1, c0t8, c0t9, c0t10, and c0t11. External are going to be c1 or something else. But, of course, that's SCSI disks. Then, if you have multipathing (say, to an external SAS array or Fiber Channel), the naming gets much more complicated.
