Linux bmp1a 2.6.16.60-0.21-SMP #1 SMP Tue May 6 12:41:02 UTC-x86_64 x86_64 x86_64 Gnu/linux

So install the SMP version of Multipath:

bmp1a:~ # RPM-IVH ultrapath-2.01.022.suse10_sp2.x86_64.smp.rpm

bmp1a:~ # Reboot

Check if Multipath is installed successfully:

bmp1a:~ # Rpm-qa | grep Ul

Ultrapath-2.01.022-1

bmp1a:~ # lsmod |grep up

Upvhba 180672 0

Upupper 340444 1 Upvhba

Scsi_mod 170936 Mptctl,upvhba,qla2xxx,scsi_transport_fc,mptsas,mptscsih,scsi_transport_sas,libata,upupper , Sg,sd_mod

Driver has been loaded, after the successful installation of multi-path software, there are two drivers exist Upvhba, Upupper, indicating that the driver loaded successfully.
