6. 安装完成。
2.2.3 配置private network
l 使用netcfg命令，配置心跳线网卡-〉ReliantHA private network
2.2.4 配置MAC Switch Driver (MSW)
l MSW的配置，使用mkmswtab命令
#/sbin/mkmswtab -i /dev/msw_0 /dev/net1 /dev/term/00t
/dev/net1为心跳线网卡，/dev/term/00t为IP心跳线
l 执行mkmswtab后系统将生成/etc/mswtab ，/etc/sdltab文件
#cat /etc/mswtab
#MSW tab - control file for msw device driver
#
#This file automatically generated by mkmswtab
#
/dev/msw_0 1 00:AA:00:BD:6F:AA
/dev/net1 0 0
/dev/sdl_0 0 1
/dev/sdl_1 0 1
#cat /etc/sdltab
#SDL tab - control file for sdl device driver
#
#This file automatically generated by sdltab
#
/dev/sdl_0
/dev/term/00t
l 重新启动主机。
2.2.5 测试MSW的安装
l 使用mswconfig命令
#mswconfig -l
Listing MAC Switch interface /dev/msw_0
MAC Address 00:AA:00:BD:6F:AA, 1 Interface, Status OFFLINE
Heartbeat ENABLED, Interval 560 msec, Misses 6
Interface 0: /dev/net1 unit 0 ONLINE, max peers 3, current peers 1

muxid 0x12, SAP 0x0000, dlpistate 0x0
2.2.6 设置Low Latency Transport (LLT)
l echo "+" >> /etc/hosts.equiv
echo "+" >> /.rhosts
l 运行
#/sbin/mkcluster -i /dev/msw_0 test1 test2
test1、test2为各节点的hostname
l 验证/etc/clustertab
#cat /etc/clustertab
The following example from the /etc/clustertab file shows a four-node cluster using the MAC switch driver:
#NodeID NodeName Device Physical Address
1 test1 /dev/msw_0 00:AA:00:A5:7F:61
2 test2 /dev/msw_0 00:AA:00:A5:1E:9C
l 重新启动主机
l 检验LLT的安装
#lltstat -a
LLT node information:
max nodes: 8, max ports: 32, this node: 1
MTU: 1500, SAP: 0xcafe
Node State
* 1 NODE_OPEN
2 NODE_IDEL
LLT port information:
- No ports active
2.2.7 配置ReliantHA
1 修改系统核心参数
/etc/conf/bin/idtune -f MSGSSZ 524288
/etc/conf/bin/idtune -f MSGMNB 65536
/etc/conf/bin/idbuild -B –K
重新启动主机
2 设置环境变量
#cp /usr/opt/reliant/etc/hvenv /.profile
退出root用户，再重新登入
2.2.8 配置举例
l IP别名
编辑/usr/opt/reliant/etc/hvipalias
test 01:AA:00:3F:19:DB /dev/net0 net0 168.33.114.100
255.255.0.0 check1 check2
field 1: 虚拟主机名
field 2: 可切换的MAC地址
field 3: 网卡设备名
field 4: 网卡接口名
field 5: 虚拟IP地址
field 6: 子网掩码
field 7: 用于网络检测的主机IP，可设置为路由器
field 8: 第二个用于网络检测的主机IP
l 将SCO提供的配置文件sybase.hl保存在/usr/opt/reliant/build目录下
内容为：
#include "defines.hl"
Cluster
{
{ SYSA,SYSB } // nodes
{ } // cluster attributes
Application // under control of Reliant
{
App1
{ SYSA,SYSB } // priority
{ AutoStartUp AutoSwitchOver } // application attributes
Process(/home/syb)
{
Pdisk(/dev/dsk/c1b0t13d3s0)
Ip ( test )
{
Nw(Nw_01, 01:AA:00:3F:19:DB)
}
}
}
}
l 编译sybase.hl
#hvgen sybase
编译生成/usr/opt/reliant/conf/sybase文件
l 将SCO提供的startdb,stopdb,syb以及应用监控脚本 (monitor, dealpro, derrpro, sendpro,recvpro,sealpro)复制到两台服务器的/home目录下
l 将/usr/opt/reliant/conf/sybase文件复制到SYSB中
#rcp /usr/opt/reliant/conf/sybase SYSB:/usr/opt/reliant/conf/.
2.2.9 启动Reliant
l #hvstart sybase
l #hvdisp –a 观察状态
l 启动/home下的应用监控程序
#/home/monitor
l #hvshut –a将停止两台服务器上的双机软件，#hvshut –l则只关闭本机的双机软件。
