SYNOPSIS:    When to do a reboot with system reconfiguration 

OS RELEASE:  2.x 

PRODUCT:     Solaris x86

KEYWORDS:    reboot reconfiguration


DESCRIPTION:

It is not always clear when a reboot with reconfiguration is necessary. 


SOLUTION:

Some guide lines are:

Additional new devices are added to the system.  This would include
adding disk drives or new controller cards. 

Any action which would result in entry changes in the /dev directory
tree.  This includes making entires in the /etc/system file which result
in the increase of devices.  An example is pt_cnt which increases the
pseudo tty count. 
 
Two methods will cause a reconfigure to occur:

 1) The existence of a file name reconfigure in the root directory.
    Generally this file is created by a "touch /reconfigure" command.

 2) A "b -r" during the "black screen" part of the boot sequence.

Several procedures are performed during a system reconfiguration:

 "drvconfig"   reconfigure devices directory

 "disks"      adds /dev entries for hard disk drives

 "tapes"      adds /dev entries for tape disk drives

 "devlinks"   adds /dev entries for miscellaneous devices 

 "audlinks"   adds /dev entries for audio devices
