DS2300 and Ultra160 mode

Hello I have a DS2300 that was originally connected to an rp5430, to a 4si card in split bus mode with 2 scsci cables & 2 terminators, and was functioning perfectly in this configuration.

Now I've connected my DS2300 to a rp4410, to an Ultra320 scsci card model (SCSI Ultra320 A6961-60011)
one scsci cable form BCC 1 channel A to the port B of the SCSI Ultra320 A6961-60011 and all the other BCC channels have a terminator on them.

I made sure that the dip switches are set to SES and Full bus mode.The problem I have now is when I run mptconfig /dev/mpt3, it states that 7 drives are set to ultra160 and the other 7 drives are set to ultra2 as shown below.Why is this?How can I make sure that all drives are set to ultra160.Thanks

mptconfig /dev/mpt3

Re: DS2300 and Ultra160 mode

SES? Is that SE SCSI or Single Ended SCSI? Should that not be set to LVD?
Anyway, it is funny that it reports everything after ID 7, it ID, is Ultra2. I would not worry since it does report it is running at Ultra160 rate
