如何分配磁盘组(EMC阵列)

« EMC Navisphere AGENT(NAVIAGENT) 安装日志 | Blog首页 | 安装Veritas Storage Fundation For Oracle Rac4.0 »

当前系统状态,可以看到lpfc启用IP功能的地址:

# ifconfig -a
lo0: flags=1000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4> mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
bge0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
inet 172.16.33.70 netmask ffffff00 broadcast 172.16.33.255
ether 0:3:ba:3c:2a:d
lpfc0: flags=1000842<BROADCAST,RUNNING,MULTICAST,IPv4> mtu 65280 index 3
inet 172.16.33.70 netmask ffffff00 broadcast 172.16.33.255
ether 0:0:c9:3d:cf:d3

在EMC中给主机分配磁盘组,此时可以看到共享磁盘,如果安装PowerPath,可以看到双路通道(本例未安装PowerPath Client):
