Finding the correct device to install onto

November 19, 2008

After spending too long today installing onto the wrong disk of an x4500 I thought I better write down how to find the right one.

The solaris install document: http://docs.sun.com/source/819-4362-16/solaris.html tells us that the bootable devices are:

Device

Slot Number

Device Node

sata3/0

0 *

c5t0

sata3/4

1 *

c5t4



Now the important thing to remember is, ignore the device nodes from the table. Instead boot of the media and use cfgadm to list the devices and the device nodes for sata3/0 and sata3/4.

# cfgadm | grep ‘sata3/[04]’     sata3/0::dsk/c3t0d0            disk         connected    configured   ok sata3/4::dsk/c3t4d0            disk         connected    configured   ok # 

So on this system and this OS (snv_101a) the boot devices are c3t0d0 and c3t4d0.
