HP双机(转自chinaunix)

1.安装好A机和B机的操作系统后,安装相应的软件MC/SG 
 
软件安装完后在安装GOLDENPATCH和最新的megaPATCH 

2.
在配置双机前必须使A机和B机能够相互信任 
使用VI 编辑文件根目录下的.rhosts,如没有,自己就建立一个 
vi .rhosts 
A  root  #A
A机的主机名 
B  root  
BB机的主机名 

3.
A机和B机上重复上面的步骤或将此文件直接拷贝至B机的根目录, 
然后使用"rlogin 主机名"在两台主机间切换,验证信任关系是否成立。 
如不需要密码认证则表示成功。 

4.
编辑/etc/hosts文件,将所有的(这里为两台主机)IP地址 
(包括心跳地址、网卡地址等)加到此文件中,以备解析时使用。 

5.
创建需要共享的VG,这里VG的创建就不详细说明了。 

6.
为双机创建锁卷组和锁磁盘 
目前比较流行的方式是利用共享的卷组作为锁卷组 
利用共享卷组中的磁盘作为锁磁盘 
举例说明如下: 
我建立了一个共享的VG名字叫VGSYB,上安装SYBASE 
在下面将要讲的如何配置群集ASCII文件的时候,里面将会碰到下面的配置 
FIRST_CLUSTER_LOCK_VG /dev/vgsyb 
FIRST_CLUSTER_LOCK_PV /dev/dsk/c4t1d2 

这里的VGSYB就是我建立的共享卷组,同时我将其也作为了锁卷组。 
这个共享卷组中的c4t1d2磁盘被我用来当作锁磁盘,这样的好处是,不用单独建立VGLOCK和锁磁盘 


7. #vgchange -a e /dev/vgsyb   
使此VG只能由一台主机接管 

8. #vgchange -a y /dev/vgsyb   
激活此锁卷组 

9. 
在其中的一台机器上执行此命令,在此我选择在A机上生成双机的配置模板 

  #cmquerycl -v  -n A
机名  -n B机名  -C /etc/cmcluster/cmclconfig.ascii 
  
如没有错误的话,将生成上面的模板文件,并用vi编辑它 

10. #cmcheckconf -v -C /etc/cmcluster/cmclconfig.ascii 
让系统检查模板 

11.
执行下面的命令前必须使锁卷组为激活状态 
#cmapplyconf -v -C  /etc/cmcluster/cmclconfig.ascii 
分发二进制文件到所有的节点 

12.#vgchange -a n  /dev/vgsyb  
停用此锁卷组,等待由双机软件来激活锁卷组 

13.#cmruncl  
启动双机 
   cmhaltcl -f  
停双机 
   cmviewcl -v  
查看双机的状态 
   cmrunnode    
启动一个节点 
   cmhaltnode   
停一个节点 

14.
注明:/etc/fstab中不能出现被双机共享的卷组 

15.
注明:以下为一个cmclconfig.ascii的文件内容,大家可以看一看里面的英文注释,及以下相关的配置参数
