Summary: sdXX -> cXtXdX

Hi. Gurus

Sorry for late summary and thanks for your effort.

I got no answer with particular rule to convert name. Almost every
messages that I recieved has solution for name converting not rule.

that is.
1) ls -l /dev/dsk/* 
2) compare iostat -x and iostat -xn
3) Using 1) or 2) write a script to convert.

Here is a script to convert sdXX -> cXtXdX by Mike van der Velden.

Thanks you guys. 

#!/bin/sh
#
#  @(#) whatdev 1.1 99/03/09
#
#  Used to convert sd instance numbers (eg. sd20) to SCSI hardware location
#  (eg. c1t5d0s0) or the other way around.  Can also list all such devices
#  by using the -all option.
#
#  Credits:
#      hw2inst() function based on "phylog" script by Nick Hindley
#      inst2hw() function based on "whatdev" script from Sun Microsystems
#
#  Revision History
#      1.1 1999-03-09  Mike van der Velden
#          Original Version.   Converts sdxx to cxdxtxsx and back.
#          Optionally lists all such devices.
