SUN Zone Cluster安装及配置说明之二
#logic address
192.168.0.121 t2000_c1
# vi /etc/hostname.e1000g0
t2000b netmask + broadcast + group ipmp1 up
# vi /etc/hostname.e1000g1
t2000b_ipmp netmask + broadcast + deprecated group ipmp1 up
dbtest_ipmp netmask + broadcast + deprecated group ipmp1 up
2.用root用户登录执行scinstall命令配置cluster。
t2000a服务器上创建新群集的第一个节点：
#scinstall
跟ufs系统装cluster不同的地方，因为zfs没有/globaldevices的分区，所以这里不选择默认的/globaldevices，而选择lofi方法。
不要自动生成投票方，安装好后手动配置投票方。
将t2000b服务器添加进节点：
应该先打开两台服务器连接心跳线的那两个网口，此处为：
# ifconfig e1000g2 plumb
# ifconfig e1000g3 plumb
# scinstall
这里选择“将此计算机添加为现有群集中的节点”
输入现有节点的主机名，即t2000a。
输入要加入群集的名称，即zfsclu (t2000a上取的名)
自动搜索群集传输，要把e1000g2和e1000g3网口打开。
这里如t2000a，选择lofi方法。
3. 给Cluster配置quorum磁盘
调配存储，在存储上划一个大小不限(1G即可)的卷作为投票方。
首先查看卷的设备名
root@t2000a # format

/pci@7c0/pci@0/pci@1/pci@0,2/SUNW,qlc@2/fp@0,0/ssd@w200600a0b8322116,1
Specify disk (enter its number):
# scdidadm –L
1 t2000a:/dev/rdsk/c0t0d0 /dev/did/rdsk/d1
2 t2000a:/dev/rdsk/c2t1d0 /dev/did/rdsk/d2
2 t2000b:/dev/rdsk/c2t2d0 /dev/did/rdsk/d2
3 t2000a:/dev/rdsk/c2t1d1 /dev/did/rdsk/d3
3 t2000b:/dev/rdsk/c2t2d1 /dev/did/rdsk/d3
4 t2000a:/dev/rdsk/c0t1d0 /dev/did/rdsk/d4
5 t2000b:/dev/rdsk/c0t0d0 /dev/did/rdsk/d5
6 t2000b:/dev/rdsk/c0t1d0 /dev/did/rdsk/d6
对照format输出的磁盘信息可知较小的卷为c2t1d1，即对应的是d3。
投票方设置：
# scsetup
选择直接连接的共享磁盘
这里选择d3作为投票方，由上面format 和scdidadm –L可知。
Is it okay to reset "installmode" (yes/no) [yes]?
scconf -c -q reset
scconf -a -T node=.
