Re: mptconfig
>> change the value of scsi to ultra160 but it is changed to ultra160
Looks like typo.
DO you mean, wanted to change to ultra160 but it changed to ultra
or .... something other than ultra160 ?

Re: mptconfig
To help you better, could you please paste the command output here.
What was the command message/warning when you changed the SCSI Bus Rate
mptconfig
ioscan
Which is your card model?
=========
In mptconfig manpage
==> Unless there is a communication problem, the rate
of ultra320 should be used for all target devices,
since the SCSI protocol automatically adjusts the
data transfer rate to compensate for slower
devices.
==> May I know why do you want to change this ??

Re: mptconfig
well, the first question i would ask is why are you dropping the speed to 160 when the drive actually is capable at 320
http://www.seagate.com/ww/v/index.jsp?vgnextoid=480d99f4fa74c010VgnVCM100000dd04090aRCRD#tTabContentOverview
then i would want to know how is the drive connected to the system? external storage? if so what type of external storage box? ds2100 for example? and what cabling?
we need to know the configuration of the system, as you could have the drive in an old box that only supports ultrawide?
hence you've changed it at the scsi controller, but in fact the box can only run at a lower speed, so it has changed to run at the speed it can
