前言：心系团圆共禅娟，把酒言欢寄情怀，一生,一世的祝福
环境介绍：
主机名称：fly007 操作系统：suse 10 sp2 64bit 存储：富士通DX8700 富士通多路径软件,版本信息如下: fly007:~ # /opt/FJSVmpd/bin/iompadm version Version 2.0.21-1.0
1、查看多路径软件链路状态，如下所示：
fly007:~ # /opt/FJSVmpd/bin/iompadm info internal error: fopen: No such file or directory: /sys/bus/mpdx/drivers/mpdh/instance_num internal error: error code = 7-2
2、重启操作系统，依然报如上错误
3、查看光纤交换机配置正确，富士通建议重装多路径软件
4、卸载多路径软件,并重启主机
fly007:~ # /opt/FJSVmpd/system/mpdpkgrm //可查看多路径软件光盘中的readme.txt Please check /etc/modprobe.conf.local and /etc/modprobe.conf, edit /boot/grub/menu.lst, make initrd and reboot this system. fly007:~ # sync fly007:~ # sync fly007:~ # sync fly007:~ # reboot
5、系统重启完毕后，检查/etc/sysconfig/kernel中的INITRD_MODULES那行是否存在lpfc，mpdh，如下所示:
fly007:~ # cat /etc/sysconfig/kernel | grep INITRD_MODULES INITRD_MODULES="mptsas processor thermal fan jbd ext3 edd bnx2 e1000 tg3 lpfc mpdh"
6、重装多路径软件，重启操作系统：
fly007: # ls MPDV2.0L21_20110202.iso fly007: # mount -o loop MPDV2.0L21_20110202.iso /mnt fly007: # cd /mnt/ fly007:/mnt # ls P2U3-0031-10ENZ0.pdf P2U3-0031-10Z0.pdf RHEL4 RHEL5 RHEL6 gpl.txt mpdpkgadd readme.txt readme_utf8.txt src fly007:/mnt # ./mpdpkgadd Progressing Preparing... ########################################### [100%] 1:FJSVmpd_se-doc ########################################### [ 50%] 2:FJSVmpd_se ########################################### [100%] ..... If you have the latest applicable patch of ETERNUS Multipath Driver, please apply it. After that, please reboot this system. If not, please reboot this system now. fly007:/mnt #cd .. fly007:~ #umount /mnt fly007:~ #sync fly007:~ #sync fly007:~ #sync fly007:~ #reboot
7、重启系统完毕后，查看多路径链路状态正常
fly007:~ # /opt/FJSVmpd/bin/iompadm info IOMP: vhba0 Element: DISK: ETERNUS_DX8000- 6A1314-0000-0002 (sdb) PATH: sdb 0000:0b:00.0 active "online" 12, 42, 15 sdb 0000:0b:00.1 active "online" 11, 41, 2
