trying to figure out a reliable way to identify drives to make sure I pull the
right drive when there is a failure. These will be smaller installations
(<16 drives)
I am pretty sure the wwn name on a sas device is preassigned like a MAC
address, but I just want to make sure. Is there any scenario where the wwn
changes?
so ideally, as long as I label the disk, with the correct wwn, then I should
be able to identify it as failed, and be able to pull it?

If you''re running S11 and have supported hardware, you might be able to see location information in format, and using the diskinfo too. Otherwise, if you''re running S11, you could try using /usr/lib/fm/fmd/fmti - a tool which blinks LEDs at you and prompts for label confirmation. James C.

These will be smaller installationshttp://support.oracle.com In the search bar in the upper right, enter: jumpstart_solution062011 There you can download a package, which includes a script... It''s really stupid. There''s a conf file for each of the supported hardware types, which simply hardcode some mappings in it. You have to select the right conf file for your system, and run slot.sh against that conf file (which you will probably copy or rename slot.conf) ... After that, it''s all simple. You just type in commands like this: Display all disks and all slots ./slot.sh -a slot.conf Display a specific disk ./slot.sh -d disk_name slot.conf Display a specific slot ./slot.sh -s slot_number slot.conf
