solaris多路径管理
root@web-db1 # reboot -- -r
运行cfgadm –al 可以看见系统已经注册了控制器，只需启用多路径mpxio即可。
root@web-db1 # cfgadm -al

注：（fp0,fp1为HBA卡上的光纤通道,fp2为本地的光线通道
fp0,fp1开启多路径，fp2关闭多路径）
root@web-db1#vi /kernel/drv/fp.conf
添加如下语句。
注释掉
#mpxio-disable="yes";
parent="/pci@8,600000/SUNW,qlc@1" port=0 mpxio-disable="no"; name="fp"
parent="/pci@8,600000/SUNW,qlc@2" port=0 mpxio-disable="no"; name="fp"
// fp0,fp1开启多路径
parent="/pci@9,600000/SUNW,qlc@2" port=0 mpxio-disable="yes"; name="fp"
// fp2关闭多路径
注:（多路径软件用于管理指向共享群集存储设备的多个I/O 路径。对于Solaris 8 或Solaris 9 操作系统，安装并配置Sun StorEdge Traffic Manager 软对于Solaris 10 操作系统，启用Solaris 多路径功能，此功能作为Solaris 10 软件的一部分已被默认安装。
以上表明在HBA卡FC接口上启用mpxio，而不是全局启用。这样正常阵列设备识别的磁盘号就为长串字符，而本地磁盘识别的磁盘号为正常的cxtxsx，因为只是在FC口局部启用的多路径，而本地禁用多路径）
root@web-db1# stmsboot –u
WARNING: This operation will require a reboot.
Do you want to continue ? (default: y) y
The changes will come into effect after rebooting the system.
Reboot the system now ? (default: y) y
在web-server2上执行相同的步骤
可以看见盘阵已经变成multipath-devices
