Controller Naming

shibz · #1 (**permalink**) 01-18-2003

Hello all,

How does the Solaris identifies the controller subscript ? ( like c0txdxs0 or c1txdxsx ?? )

I have a unix box ( Ultra 30) running with 2.5.1.

When I connected an external hard disk to the on-board scsi port, it got identified as c0t1dxsx...

( /devices/pci@1f,4000/scsi@3/sd@1 )

But when I connected a dot hill raid box to the same port, it got identified as c1t1dxsx

( /devices/pci@1f,4000/scsi@3,1/sd@1 )

The raid box has an in built controller. Its quite logical to think that this could be due to that built-in controller of the raid-box. ( Am i correct ? )

I hope somebody can throw more information on this topic

Thanks in advance...

See HOW PERIPHERAL DEVICES ARE LOCATED.

(and yes, since there is a controller in the raid box, it's seen as the second (number start at 0) controller giving it a number 1.
