[求助]RHEL4U4下的SAN多路径问题(HP EVA4000,emulax光纤卡)

skysnowolf

设备情况：
存储设备为HP EVA4000双控，光纤交换机为HP OEM Brocade 4/12 SAN Switch（刀片模块型）
服务器IBM X3650，x64 cpu，8G内存，光纤卡是IBM OEM emulax lpe11002的4gbps 双端
虽然服务器的光纤卡是双端口，但是因为光纤交换机口不够，只是接了一条光纤线到光纤交换机。因为EVA4000是双控，所以在linux操作系统下，每个LU还是认到2条路径。

OS是RHEL 4U4版本，安装了HP eva4000 for rhel4u4 for emulex的驱动。启动的时候都能认到SAN的磁盘设备。跑的是oracle 10g应用。

问题一：
dmesg中发现有这样的错误信息：
device-mapper: dm-multipath: Failing path 8:192.
但是，oracle应用却好像没事一样，而且打multipath -ll也没有发现failed或者faulty的错误。

问题一：
#multipath -ll，发现有些LU的两个路径是active/enabled的，有些是enabled/enabled，很奇怪。

不知道会不会有什么问题？？？

active - Path group currently receiving I/O requests.
enabled - Path groups to try if the active path group has no paths

in the ready state.

disabled - Path groups to try if the active path group and all

enabled path groups have no paths in the active state.
