System configuration and device overview

# $nderstanding the configuration of the system is important. ' 6he configuration should be documented and updated on a regular

basis.# ll de%ices ha%e attributes! some of which can be changed.

' lsattr! lists de%ice attributes ' chde%! changes de%ice attributes

# Most de%ices within I4 are self configured! through cfgmgr.# &e%ice states can be controlled using mkdev and rmdev

commands. ' Including %irtual de%ices

# emember7 n I4 partition does not need to ha%e anyphysical de%ices.

Device addressing

# 6he address of a de%ice allows you to identify its location.# 6here are two types of &e%ice addressing.

' )hysical location codes refer to a specific component. ' ssigned by the system firmware

# Aample. hdis 0" $E< 0.00@.&F (( 4/)2/&5 1 1 &ri%eD

' 3perating system location codes also refer to components but use adifferent con%ention! assigned by I4. ' Fot as useful or meaningful as )hysical codes on )3 5 or

)3 ; systems ' ,irtual de%ices do not ha%e I4 location codes.
