DS4300存储一台 串口线一根

3. 系统环境

3.1 /etc/hosts

127.0.0.1 loopback localhost p630a(另一节点为p630b) 192.168.1.100 p630a_stb 192.168.1.200 p630b_stb 192.168.2.100 p630a_boot 192.168.2.200 p630b_boot 192.168.3.100 p630a_svc 192.168.3.200 p630b_svc 3.2 /.rhosts 192.168.1.100 192.168.1.200 192.168.2.100 192.168.2.200 192.168.3.100 192.168.3.200

3.3 clcomdES

/usr/bin/startsrc -s clcomdES

3.4 确认网卡之间相互连通 确认串口线的连通

smitty tty->Change / add a TTY->rs232->sa->port number : 0

确认：

host1: cat /etc/hosts>/dev/tty0 host2: cat在 host2 可看到 host1 上 /etc/hosts 的内容。 同样再做反向检测

4. 配置HACMP

（以下操作只需在一个节点上操作即可）

4.1.2 配置Cluster节点

# smitty hacmp Extended Configuration

Add a Node to the HACMP Cluste

*NodeName [NodeA] Communication Path to Node [p630a_boot] +

以同样方法将NodeB添加到Cluster中

*NodeName [NodeB] Communication Path to Node [p630b_boot] +

4.1.3 配置HACMP网络 4.1.3.1 创建IP网络

# smitty hacmp Extended Configuration Extended Topology Configuration Configure HACMP Networks

Add a Network to the HACMP Cluster

* NetworkName [net_ether_01]

* NetworkType ether * Netmask [255.255.255.0] + * Enable IP Address Takeover via IP Aliases [Yes] +

IP Address Offset for Heartbeating over IP Aliases [] 使用同样的方法创建[net_ether_02]

* Enable IP Address Takeover via IP Aliases [Yes] 此选项决定了HACMP的IP切换方式，但值得一提的是只有“boot”、“standby”、“service”三个IP分别为三个不同网段时必须选用IP Aliases方式。如果“boot”、“standby”其中一个与“service”为同一个网段时必须选用IP Replace，则此选项应选“NO”。

4.1.3.2 创建串口心跳网络

# smitty hacmp Extended Configuration Extended Topology Configuration Configure HACMP Networks

Add a Network to the HACMP Cluster

* NetworkName [net_rs232_01]

* Network Type rs232 第4页/共9页

4.1.3.3 创建磁盘心跳网络

# smitty hacmp

Extended Configuration

Extended Topology Configuration

Configure HACMP Networks

Add a Network to the HACMP Cluster

* Network Name [net_diskhb_01] * Network Type diskhb

Add Pre-defined Communication Interfaces and Devices Communication Interfaces

* IP Label/Address [p630a_boot] +

* Network Type ether * Network Name net_ether_01 * Node Name [NodeA] +

Network Interface [] 同样方法添加另一个通信接口到”net_ether_01”

* IP Label/Address [p630b_boot] +

* Network Type ether * Network Name net_ether_01 * Node Name [NodeB] +

Network Interface []

* IP Label/Address [p630b_ stb] +

* Network Type ether * Network Name net_ether_01 * Node Name [NodeB] +

Network Interface []

4.1.4.2 创建串口通信设备 第5页/共9页

HACMP 配置文档

# smitty hacmp Extended Configuration Extended Topology Configuration Configure HACMP Networks

Configure HACMP Communication Interfaces/Devices Add Communication Interfaces/Device

Add Pre-defined Communication Interfaces and Devices Communication Devices

* Device Name [rs232_node_a]

* Network Type rs232 * Network Name net_rs232_01 * Device Path [/dev/tty0] * Node Name [NodeA] +

以同样方法创建另一个串口通信设备

* Device Name [rs232_node_b]

* Network Type rs232 * Network Name net_rs232_01 * Device Path [/dev/tty0] * Node Name [NodeB] +

4.2 配置HACMP资源 4.2.1 配置资源

4.2.1.1 创建Applications Servers

# smitty hacmp Extended Configuration

Extended Resource Configuration

HACMP Extended Resources Configuration Configure HACMP Applications Servers Add an Application Server

* Server Name [appserver]

* Start Script [/hascript/clstart.sh] * Stop Script [/hascript/clstop.sh]

需要手动在两个节点上建立“/hascript/clstart.sh”、“/hascript/clstop.sh”并保证其有执行权限。如果是双机互备的话需要建立两个App Server。方法相同。

4.2.1.2 创建Service IP

# smitty hacmp Extended Configuration

Extended Resource Configuration

HACMP Extended Resources Configuration

Configure HACMP Service IP Labels/Addresses

Add a Service IP Label/Address

Configurable on Multiple Nodes

* IP Label/Address p630a_svc +

* Network Name net_ether_01 第6页/共9页

HACMP 配置文档

同样方法配置第二个Service IP

* IP Label/Address p630b_svc +

* Network Name net_ether_01

4.2.2 配置资源组 4.2.2.1 创建资源组

# smitty hacmp Extended Configuration

Extended Resource Configuration Add a Resource Group

* Resource Group Name [rg_node_a]

Participating Nodes (Default Node Priority) [NodeA NodeB] +

Startup Policy Online On Home Node O> + Fallover Policy Fallover To Next Prio> + Fallback Policy Fallback To Higher Pr> + 如果是双机互备的话以同样方法建立另一个资源组

* Resource Group Name [rg_node_b]

Participating Nodes (Default Node Priority) [NodeB NodeA] +

“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：

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。

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。 Online Using Distribution Policy：按照分布策略启动 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：

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

Fallover Using Dynamic Node Priority：节点失败时动态选择迁移节点 Bring Offline (On Error Node Only)：将资源组下线

Fallback Policy：

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

Never Fallback：不进行资源组回迁

4.2.2.2 配置资源组属性

* Logging [Standard] +

6. 启动/停止HACMP
