Has anyone ever thought of integrating SES managed enclosures into the kernel RAID system? I briefly looked through the archives and have not found anything on the topic. Some HW based RAID controllers do this flawlessly now, there is no reason why the kernel RAID cannot also. (LSI MegaRAID) 1) When a drive is part if a managed enclosure, the RAID system should address it by location instead of by enumerated device node. The SES device in the enclosure can map the physical slot to a physical drive. The RAID admin (mdamd) should be able to add/fail/identify devices based on slot. 2) If the RAID system fails a drive, it should notify the SES management and turn on the fail bit and the fail LED. 3) The RAID system should be able to turn on the 'identify' bit and LEDs for an array or a single drive. I'm currently doing firmware on a managed enclosure. Although my vendor only supports LSI MegaRAID, there is no reason why my enclosures cannot work in the same manner on a kernel RAID system.
