Dynamic Discovery of SAS Devices

SAS devices, added and removed dynamically with the mpt(7d) driver, enable your
system to detect specific targets and LUNs attached, with these conditions:
If you add or remove a device in your SAS domain, messages are written to the
■
/var/adm/messages file indicating presence or removal.
If a device has been added, it is visible to, and available by, the format(1m)
■
command.
Note – To clean up the CTD# for your device tables, run the following command:
devfsadm -C.
