It is still not correct.  The product id "MD Virtual Disk" is the device claimed by MPP. That means you still have mpp in your system.

 

Please follow the steps below..

 

  1. Remove the MPP from your system.

Find the directory where MPP sources are located. It should be somewhere in /opt/.  Then run "make uninstall"

 

      2. Send me output of /proc/scsi/scsi


Ok. Thank you for spotting this.

The Makefile resided in /usr/src/linuxrdac-09.03.0C06.0030
I did the following to stop the mpp modules from loading at boot:

i first did:

 # cd /usr/src/linuxrdac-09.03.0C06.0030
 /usr/src/linuxrdac-09.03.0C06.0030 # make uninstall

This removed some files (amongst others the files in /opt/mpp)

I rebooted, but the the mpp* drivers still were loaded after reboot.

I then changed the /etc/modprobde.conf and commented out the mpp drivers:

#alias scsi_hostadapter0 mppVhba
#alias scsi_hostadapter1 mppUpper

This was not enough, I still had the mpp* drivers after reboot.

So I looked in /boot and found an "old" version of initrd, and I assume
this was the initrd used before the mpp driver was installed.
So I changed /boot/grub/menu.lst to use the "previous" initrd, and then rebooted.
Now, I don't have any mpp drivers loaded anymore.

And here's the output of /proc/scsi/scsi:

# cat /proc/scsi/scsi
