It depends on whether you have the HBA configured in RAID mode or not. If you have, then it takes absolute control of the enclosure management at the moment and I don't think you can get to it. If you run the HBA as a pure SAS one, then the promise website says this enclosure is ses2 compliant, so you should just be able to insert the ses module and have enclosure management (2.6.24+ kernels). This relies on the HBA exposing the enclosure device, but I think mptsas only eats it for RAID configurations. to see what's in the enclosure, just do ls /sys/class/enclosure/*/ each of the subdirectories has a slot label (name taken from SES) to locate the enclosure, just echo 1 to the locate file and it will flash the lights. If it has a disk, there should be a device link in the slot directory (might not be, this depends on ses working correctly and VPD inquiries identifying the right disk).
