所以安装smp版本的多路径：bmp1a:~ # rpm -ivh UltraPath-2.01.022.SUSE10_sp2.x86_64.smp.rpm
bmp1a:~ # reboot
检查多路径是否安装成功:bmp1a:~ # rpm -qa | grep UlUltraPath-2.01.022-1bmp1a:~ # lsmod |grep upupVhba 180672 0 upUpper 340444 1 upVhbascsi_mod 170936 11 mptctl,upVhba,qla2xxx,scsi_transport_fc,mptsas,mptscsih,scsi_transport_sas,libata,upUpper,sg,sd_mod驱动已经加载，多路径软件安装成功后，有两个驱动存在upVhba、upUpper，表示驱动加载成功。
