Have m1115 on workstation, out to DAS with IBM sas expander, with about 8 JBOD drives. Lately the JBOD unit has been beeping like crazy! Can't really tell whether it is mobo fault (an old mobo without processor, ram etc, just to power sas expander), or the expander, or the power supply! But makes me nervous! Any ideas what it could be? High pitched beeping, which seems to calm down/stop after a bit sometimes..but not always! HDD about to die?

Unlikely to be a disk failure, unless you are seeing errors being reported. My money would be on the power supply, start there, process of elimination an all that :)

if your controller has a battery it could be the battery overheating.
point Megaraid manager at it and it will tell you what is complaining and allow you to silence the alarm
