We see this on numerous Dell hosts running the SAS6iR based on the LSISAS1068E
chip. Running the stock RHEL5 driver.
It's simple to reproduce with SMART commands, but we actually see huge issues
with drives dropping off cards even during heavy I/O and no SMART commands
involved at all. It seems to be all the worse when the disk reallocates a bad
sector. The disks are Dell-supplied and therefore 'enterprise' models capable
of TLER type behaviour.
I believe the SMART command method makes it easier to reproduce what may be a
problem not specifically related to SMART, but that's just my own feeling.
HTH.
