I use both external connections to both expanderboards of the enclosure just for redundancy.

So this will never work for the SATA discs in our enclosure, right? Or is there a chance with asking LSI to do something in their firmware?

Seems I have no chance to get to know which slot contains the failed drive without a shutdown. Bad luck.
