SUSE linux 10sp2安装多路径软件

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

附加：

卸载多路径

如果不再使用多路径，可以将多路径卸载，卸载前请停止业务。

去激活所有虚拟盘上的VG。

1） 卸载LV的挂载点；

2） 查询虚拟盘上的VG状态是否为active状态；去激活虚拟盘上的VG

3） 卸载多路径

# rpm –qa |grep Ul 或者rpm –qa |grep Up

查询得到安装的多路径软件包名

# rpm –e 包名

卸载成功

4） 重启主机

# reboot
