This sort of worked, but:
Version 9 have me very poor performance with drives. While drives
typically do 150MB/s sequential, I could never get more than half of
that. Even when using only one drive. At some point, after reboot it
started discovering four expanders.. It's BIOS complained at boot time
loudly, etc. Performance did not change.
Version 8 (supposedly the fixed one), too had poor performance, had the
same issues with multiple expanders, but also the disks devices were
multiplied four times.
So I went back to flash the original SMC2008 firmware (version 7), which
went fine, performance is ok, nothing is multiplied :) Weird, it claims
to be IR firmware, but I ended up in IT mode, which is what I need anyway.
Looking at the batch file for the SMC firmware, it does erase with "7",
instead of with "6". Probably it is necessary to erase the flash more
than LSI suggests. Haven't tried yet.
Should I worry for not running the latest firmware?
