# smit vg
Add a Volume Group with Data Path Devices
VOLUME GROUP name [datavg] + Physical partition SIZE in megabytes 256 * PHYSICAL VOLUME names [vpath0 vpath1 vpath2 vpath3 vpath4 vpath5 vpath6 vpath7 vpath8 vpath9 vpath10 vpath11 vpath12 vpath13 vpath14 vpath15 vpath16 vpath17 vpath18 vpath19 vpath20 vpath21 vpath22 vpath23 vpath24 vpath25 vpath26 vpath27 vpath28 vpath29 vpath30] Force the creation of a volume group no + Activate volume group AUTOMATICALLY no + at system restart? Volume Group MAJOR NUMBER [61] Create VG Concurrent Capable? yes Auto-varyon in Concurrent Mode? no Create a big VG format Volume Group? yes Create a scalable VG format Volume Group? no |
*big vg是IBM为Oracle等数据库特定的一种VG。
1.1.2 主机A导出datavg信息给主机B#smit vg
Export a Volume Group
* VOLUME GROUP name [datavg]
导出后本节点看不到datavg。
1.1.3 主机A导入datavg信息#smit vg
Import a Volume Group
VOLUME GROUP name [datavg]
*PHYSICAL VOLUME name [vpath0]
Volume Group MAJOR NUMBER [61]
1.1.4 主机B导入datavg信息
# smitty vg
Import a Volume Group
Type or select values in entry fields. Press Enter AFTER making all desired changes. [Entry Fields]
VOLUME GROUP name [datavg] * PHYSICAL VOLUME name [vpath0] + Volume Group MAJOR NUMBER [61] +# |
两台主机的VG major number要保持一致!
1.1.5 查看VG状态创建成功后,查看主机A和主机B的pv:

1.2 心跳线配置及测试在选择哪个串口作为心跳线的端口时,原则是这样:
在串口富裕的情况下,尽量不要选择第1个和第2个。(因为第一个串口一般做console,第二个常用作远程维护程序使用)。
如果不这样,虽然同步和简单的测试没有问题,但在实际应用中回出现HACMP经常自动切换,所以应该不使用第1和第2个串口。
1.2.1 心跳线配置#smitty tty
Add a TTY
TTY type tty TTY interface rs232 Description Asynchronous Terminal Parent adapter sa0 * PORT number [0] + Enable LOGIN disable + BAUD rate [9600] PARITY [none] + BITS per character [8] + Number of STOP BITS [1] + TIME before advancing to next port setting [0] + TERMINAL type [dumb] FLOW CONTROL to be used [xon] |
主机2步骤与主机1相同。
1.2.2 心跳线测试在两台主机上,通过lsdev –Cc tty查看新增的串行口,会有类似下面的内容:
tty0 Available 00-00-S3-00 Asynchronous Terminal |
序号 |
主机 |
内容 |
1. |
主机1 |
stty |
2. |
主机2 |
stty 这时在两台主机的命令行下会有内容的显示,否则,tty配置失败。示例如下: speed 9600 baud; -parity hupcl eol2 = ^? brkint -inpck -istrip icrnl -ixany ixoff onlcr tab3 echo echoe echok |
3. |
主机1 |
cat /etc/hosts > /dev/tty0 |
4. |
主机2 |
cat < /dev/tty0 这时在主机2的命令行下有主机1的/etc/hosts文件的内容,否则,tty配置失败。 |
2. 安装HACMP 2.1 安装HACMP5.4
将HACMP V5.4 软件CD放入CD-ROM,在主控台上执行以下操作:
#smitty installp
Install Software
INPUT device / directory for software [/dev/cd0]
SOFTWARE to install [不选择cluster.haview,
cluster.hativoli]
ACCEPT new license agreements? yes
2.2 升级到HACMP 5.4.1由于Oracle 10g RAC需要HACMP版本为5.4.1,可以从IBM官方网站下载5.4.1的最新补丁。
#smitty installp
Update Installed Software to Latest Level (Update All)
ACCEPT new license agreements? yes
2.3 查看HACMP版本#lslpp -l |grep cluster

“Participating Nodes”选项决定了资源组中节点的优先级,写在前面的节点其优先级高于后面的节点。
根据实际需求决定资源组的:“Startup Policy”、“Fallover Policy”、“Fallback Policy”。
Startup Policy:
n Online On Home Node Only: 只在主节点启动。在 “Participating Nodes”中写在第一位的节点启动。
n Online On First Available Node:在第一个启动的节点启动。在“Participating Nodes”中所选择的所有节点中最先启动的节点上启动。
n Online Using Distribution Policy:按照分布策略启动
n Online On All Available Nodes:在所有启动的节点中启动。做并发群集时选择此项。如:Oracle RAC
Fallover Policy:
n Fallover To Next Priority Node In The List:节点失败时资源组迁移到下一优先级节点
n Fallover Using Dynamic Node Priority:节点失败时动态选择迁移节点
n Bring Offline (On Error Node Only):将资源组下线
Fallback Policy:
n Fallback To Higher Priority Node In The List:节点恢复时资源组返回优先级高的节点
n Never Fallback:不进行资源组回迁

4.1 HACMP同步失败报错信息如下:
ERROR: Verification of Cluster Topology for RSCT failed. See “/var/ha/log/topsvcs.default” for detailed information. WARNING: File ‘netmon.cf’ is missing or empty on node gdapp1. This file is needed for a cluster with the single-adapter network net_rs232_01. Please create ‘netmon.cf’ file on node gdapp1 as described in ‘HACMP Planning and Installation Guide’. WARNING: File ‘netmon.cf’ is missing or empty on node gdapp2. This file is needed for a cluster with the single-adapter network net_rs232_01. Please create ‘netmon.cf’ file on node gdapp2 as described in ‘HACMP Planning and Installation Guide’. |
解决方法:
到两个节点的/usr/sbin/cluster目录下检查是否有netmon.cf文件,如果没有,请增加该文件,并增加内容;如果有,请检查内容,内容如下:
10.19.98.18 10.19.98.22 10.19.98.17 10.19.98.19 192.168.254.3 192.168.254.4 |
以root用户执行
#ps -ef|grep ora
保证没有oracle进程运行
查看 hacmp进程
lssrc -g cluster
可用 stopsrc -s service_name来停HACMP的子系统,例如:
#stopsrc -s clinfo
