我的机器上安装了两个EMULEX 4Gb的HBA卡，
以前在服务器上安装的rhel-server5.4-x86_64 配置上都没什么问题，但是因为5.4不符合要求，换成rhel-server5.2-x86_64后，使用multipath -v3这个命令不能刷出wwid信息了，反馈信息如下：

兄弟我很是郁闷，setup中开启multipathd服务，重启服务器，重启日立存储，问题依旧。。
后来我把系统的multipath.conf配置文件改名备份后，直接将以前在5.4上做好的multipath.conf配置文件传上去，重启multipathd服务后multipath -ll查看， 竟然能看到我的multipath.conf配置生效了！！可是回头再去multipath -v3 依然不能打印wwid等信息，无奈我重启服务器后离开机房，到楼上办公室以后登上服务器multipath -v3一把 wwid等信息如约而至，这是为什么呢？ 真是太混蛋了。
兄弟我在服务其上面装了这些包，可以断定不是缺包的问题，因为我是按照要求被迫在图形安装界面上把所有的包统统都安装了的。
[root@iosrv ~]# rpm -qa |grep mapper
device-mapper-event-1.02.24-1.el5
device-mapper-1.02.24-1.el5
device-mapper-1.02.24-1.el5

现在能够成功执行multipath -v3之后的到得信息如下，这个信息是正确的。

请各位的大侠帮忙分析一下，问题到地处在啥地方，如果兄弟我没有保留以前在5.4上的multipath.conf配置文件，那今天就真的折了。
怪怪，你说这是为什么呢？
附上我的multipath.conf配置文件，没准儿能帮某些兄弟做为multipath配置的参考
[root@iosrv ~]# cat /etc/multipath.conf
# This is a basic configuration file with some examples, for device mapper
# multipath.
# For a complete list of the default configuration values, see
# /usr/share/doc/device-mapper-multipath-0.4.7/multipath.conf.defaults
# For a list of configuration options with descriptions, see
# /usr/share/doc/device-mapper-multipath-0.4.7/multipath.conf.annotated
# Blacklist all devices by default. Remove this to enable multipathing
# on the default devices.
blacklist {
devnode "sda"
}
## By default, devices with vendor = "IBM" and product = "S/390.*" are
## blacklisted. To enable mulitpathing on these devies, uncomment the
## following lines.
#blacklist_exceptions {
# device {
# vendor "IBM"
# product "S/390.*"
# }
#}
## Use user friendly names, instead of using WWIDs as names.
defaults {
user_friendly_names yes
}
##
## Here is an example of how to configure some standard options.
##
#
#defaults {
# udev_dir /dev
# polling_interval 10
# selector "round-robin 0"
# path_grouping_policy multibus
# getuid_callout "/sbin/scsi_id -g -u -s /block/%n"
# prio_callout /bin/true
# path_checker readsector0
# rr_min_io 100
# max_fds 8192
# rr_weight priorities
# failback immediate
# no_path_retry fail
# user_friendly_names yes
#}
##
## The wwid line in the following blacklist section is shown as an example
## of how to blacklist devices by wwid. The 2 devnode lines are the
## compiled in default blacklist. If you want to blacklist entire types
## of devices, such as all scsi devices, you should use a devnode line.
## However, if you want to blacklist specific devices, you should use
## a wwid line. Since there is no guarantee that a specific device will
## not change names on reboot (from /dev/sda to /dev/sdb for example)
## devnode lines are not recommended for blacklisting specific devices.
##
#blacklist {
# wwid 26353900f02796769
