I find it very hard to locate which slot a certain/failed disk is located in, is there not some way to flash the LED light on the drive/array to locate the drive just like a server can be located by turning on the "locator LED"?
I am using Solaris 11 on a T2000 via two LSI/SAS/SATA HBAs and 16 direct connected drives.

Assuming the drive can still be interrogated by format(1M),
try this old hack:
format -> analyze -> read

Thats one function the storage vendor typically provides, rather than
the OS. And for many of these, they embed pictures of the shelf used,
and the location of each disk within so they can light up where the
bad disk is off a map.
You don't say what kind of disk shelf you have, but some of the Sun
branded ones have this function built in.
If this is a generic shelf, then you'll have to keep track of things yourself.
Ie. for our built up storage boxes, we keep a spreadsheet with all the
drive WWNs when we build it. When a drive goes out, we update the spreadsheet.

right I was hoping for some progress in this, but paper is always good works when light are out aswell :)
I though that there was some standard I/F from the HBA that did this.

DEC and later Compaq made disk systems using SCSI disks. The drives all had an LED on the front panel that, when lit, meant that there was a problem. So it certainly CAN be done. If it's not done, look at the
economics! "Follow the money!"

John's suggestion works for drives that format can see. For those it can't, running a zpool scrub will active ate the status LEDs on all the other drives!

sadly, I think HP may be the last name in the game with disk enclosures with meaningful indicator lights. Bright orange = failed. Blue = drive selected by array software for location, green = doing stuff.
Even Netapp stuff seems to lack a fault LED of any sort, and they rip you off pretty good, so it's not like the can't pick to demand enclosures with 14 extra LEDs installed.
Why people wimp out on stuff like this really bugs me.
