bmp1a:~ # uname -a
Linux bmp1a 2.6.16.60-0.21-smp #1 SMP Tue May 6 12:41:02 UTC 2008 x86_64 x86_64 x86_64 GNU/Linux
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 Ul
UltraPath-2.01.022-1
bmp1a:~ # lsmod |grep up
upVhba 180672 0
upUpper 340444 1 upVhba
scsi_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。
查看启动项是否更改正确：
