SUSE linux 10sp2安装多路径软件

浏览数：24 / 时间：2015年06月20日

明：存储为华赛的S5300，如果存储为IBM或其他厂商的话，操作方法不一样，请注意！

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：

bmp1a:~ # cat /boot/grub/menu.lst

说明：default 后面对应参数表示默认是从第几个启动项启动，对应找准启动项名称是以“title Linux with UltraPath”打头，表示启动项已经被修改正确
