MPTSAS: ("activate status led" | "find disc") in external enclosure

["Lars Täuber" <taeuber@bbaw.de>]

Hallo!

As some of you might already now I have to set up a (for us) bigger SAN with Linux.
I'm simulating disc failure right now. To find a defective disc in the enclosure is unresolved yet.
I already had a look at several web pages and searched for it but without luck.

The manual of the enclosure says (PROMISE VTRAK J610S):
-----------------------------------------------------------------------
LEDs                                 State
                | Dark     | Steady Green  | Flashing Green
Power/Activity* | No Drive | Drive Present | Activity
Status**        | HBA/RAID controller determines the LED behavior
[...]
** Refer to the user documentation for your HBA or RAID controller for this
   information.
-----------------------------------------------------------------------

Is there a standard way to lit the led in the enclosure with linux means or anything alike?
The enclosure does not tell the serial numbers of the included disc.
The HBA is an LSI SAS 3801X.


Thanks
Lars
