构建AIX环境下的RAC之--建立并发卷组（4）
环境：
操作系统： AIX 5300-09
集群软件： CRS 10.2.0.1
数据库： Oracle 10.2.0.1
本案例是用于基于VG Concurrent 的共享存储，通过HACMP 实现卷组的并发
16、在阵列上建立共享lun
首先在阵列上划分共享的lun，本机以SUN T300为案例：
------配置阵列，建立共享磁盘
阵列操作：
阵列型号：SUN T3
1）、建立一个新卷（RAID5）
vol add ljg01 data u1d1-8 raid 5 standby u1d9
2）、初始化
vol init v01 data
3）、挂接到系统
vol mount v01
4）、分配LUN(p)
volslice create aix211_212_1 -z 100GB v01
5）、设置所有的lun为none，这样所有的主机默认都不能访问lun，指定特定的主机访问
lun default all_lun none
主机端:
6）、获得AIX主机连接的光纤设备（HBA):
bash-3.00# lsdev -Cc adapter -S a | grep fcs
fcs0 Available 10-88 FC Adapter
7）、查看光纤卡的WWN号
bash-3.00# lscfg -vpl fcs0

阵列端：
8）、添加WWN
lun perm lun 0 rw wwn 10000000C93ADF48 (两个节点都要添加)
lun perm lun 1 rw wwn 10000000C92EA568
建立阵列lun 和主机HBA 的映射，这样只有特定主机才能访问lun
主机端：
9）、主机重新加载阵列
bash-3.00# cfgmgr -v 主机读取ODM库，识别先加入的磁盘
17、建立并发卷组
1）查看磁盘pv信息
[root@aix211 /]#lsdev -c disk
hdisk0 Available 1S-08-00-8,0 16 Bit LVD SCSI Disk Drive
hdisk1 Available 1n-08-02 Other FC SCSI Disk Drive
[root@aix211 /]#lspv
hdisk0 00040f8aaa29d28e rootvg active
hdisk1 000e1a6ce663b4af
2）建立卷组
[root@aix211 /]#smit mkvg
在另外一个节点导入vg：
[root@aix212@ /]#smit importvg
在并发卷组上建立逻辑卷：
[root@aix211 /]#lspv

注：在配置完HACMP后，并发卷组在所有节点上的状态应该是concurrent。
[root@aix212@ /]#lspv
