same here:
mps0@pci0:5:0:0: class=0x010700 card=0x30201000 chip=0x00871000
rev=0x05 hdr=0x00
vendor = 'LSI Logic (Was: Symbios Logic, NCR)'
class = mass storage
subclass = SAS
mps0: Firmware: 14.00.00.00, Driver: 14.00.00.01-fbsd
This controller (LSI 9207-8i) seems to store some history info about
all previously inserted disks and increments the target id on every
new disk. This should IMHO not happen, at least if the controller is
flashed with IT-Firmware.
I solved this issue by erasing region 3 (persistent configuration
pages) via sas2flash.
As this particular function is disabled in the FreeBSD version, I had
to use the DOS-Version: "sas2flsh.exe -o -e 3"
After executing this command the target id starts with 0 again.
Hopefully this annoying issue will be solved in a future firmware release.
HTH.
