It's supposed to be the same, you can look in /etc/rcS.d to see.  However,
my experiences with my three E4500s says that sometimes the
drvconfig/devlinks/disks triplet will hang on high-lun-count systems while a
"boot -r" will always work.

You're right in that the sd module has to reload to pick up changes in
sd.conf, this triplet commands will not pick up changes here.

Afak, the only difference between drvconfig/devlinks/disks and a
reconfiguration reboot is disks/controlers modules reload, so that config
files could be re-read.
If you don't update config files like sd.conf, I think a reconfiguration
reboot is similar to drvconfig/devlinks/disks because you don't have to
reload modules.

	A great deal of hardware is hot-swappable on Sun hardware, disks on
the E4x0
	series for example.

	The E3500, however, only allows disks to be added internally via an
internal
	disk board (a waste of a valuable system slot) or via external disk
packs
	and a SCSI cable.  There's no issues to adding external disks hot.

	Adding internal disk boards is not mentioned among the highly
available
	features available on the E3500, however.  You can read that page
here:
	http://www.sun.com/servers/midrange/e3500/details.html#g2_5 and even
then,
	the hot-swap "dynamic reconfiguration" options are described as
supported on
	sol 7 & 8.  I'd recommend adding a new disk board while cold on a
v2.6
	system.

	The newly added external disks can be discovered with a reconfig
reboot
	(boot -r) or by doing these three commands in sequence while the
system is
	up:

	drvconfig && devlinks && disks

	Note that these can take quite a while on some systems and they
don't
	necessarily work as reliably as a reconfig reboot.

	Good luck,
	Mark

	Hello,

	I have a SUN E3500 server running Solaris 2.5, I need to add a disk
to the
	system itself, do I need
	to power off the server or I can add it on the fly, what commands do
I need
	to
	do on the server to make
	it see the disk.

	Many Thanks,
	Feras.
