This reminds me of an old thread in freebsd-scsi, where a guy with some
SAS disks and a SAS2008 controller would have his disks 'lost' if he
used smartctl on routine, and could reproduce it reliably by spamming a
disk with smartctl -a (but smartctl -i, and something else would not
reproduce it). And he found that to solve it, he can change the "disk
tags" to much lower. I think "disk tags" might be equivalent to the
nr_requests in Linux.
Here is the thread:
