檢視cluster是否啟動:
lssrc -g cluster

啟動和停止cluster
#smitty clstart /smitty clstop

,檢視cluster服務情況
# tail –f /var/hacmp/log/hacmp.out

檢視ha ip服務情況
#/usr/sbin/cluster/clstat

# netstat –in (檢視網路狀態資訊)

建立共享資料儲存區prodvg
#smitty mkvg
然後輸入要建立VG 的名字：prodvg，選擇硬碟：hdisk4;按回車執行。
#smitty chvg
來改變prodvg 的狀態，要把重啟系統後自動啟用卷組改為NO。
然後再prodvg 上建立邏輯卷和檔案系統。
分別用#smitty mklv 和#smitty fs
最後要在這臺機器執行：#varyoffvg prodvg 來停止這個共享卷組。
換到另一臺機器，用#smitty importvg 來匯入這個共享卷組，輸入卷組的名字：prodvg ；選
擇硬碟：hdisk7（因為在erp 這臺機器有多個硬碟，看PVID 號得出hdisk7 是共享的資料盤）
匯入prodvg 後，我們在這臺機器也要改變VG 的屬性。
#smitty chvg
要把重啟系統後自動啟用卷組改為NO

分別選擇ether,diskhb,rs232

串列埠做心跳:
Smitty tty
選擇“Add a TTY”

lsdev –Cc tty 檢視新增串列埠，會有如下顯示：
tty0 Available 00-00-S3-00 Asynchronous Terminal

串列埠測試：
【

1.


主機A


stty
2.


主機B


stty
這時在兩臺主機的命令列下會有內容的顯示，否則，tty配置失敗。示例如下：

speed 9600 baud; -parity hupcl

eol2 = ^?

brkint -inpck -istrip icrnl -ixany ixoff onlcr tab3

echo echoe echok

3.


主機A


cat /etc/hosts > /dev/tty0

4.


主機B


cat < /dev/tty0

這時在主機2的命令列下有主機1的/etc/hosts檔案的內容，否則，tty配置失敗。

完成串列埠測試

配置HACMP (以下我們以主機A作為主機，B作為備用機)
【

(cluster name-cluster node-discover 發現-HACMP networks-新增HACMP IP地址或hacmp communication interfaces/deves 介面和串列埠裝置-hacmp persistent NODE ip label/address 新增現有節點的IP及標識，地址。)HACMP的配置都是在一臺主機上做配置，作完之後，只需要同步另外一臺主機即可。節點名兩臺主機要分別新增。

詳細配置

<1>配置CLUSTER NAME 及節點；分別將NODE加入CLUSTER叢集中，然後在發現一下。

Communication path to node 這一步選擇透過發現方式來選擇node對應的主機(boot1/boot2)，分兩次來完成,不同的node來對應不同的主機

<2>給HACMP新增IP網路

Smit/smitty hacmp—Extended Topology Configuration--&gtConfigure HACMP Networks->Add a Network to the HACMP cluster

選擇ETHERNET，新增IP網路（該資訊都是自動獲取無需修改任何引數設定，只需要修改最後一項，選擇YES OR NO）

其中Enable IP Takeover via IP Aliases項，如果SVC IP地址與boot1地址在同一網段，則選擇“NO”，反之選擇“YES

<3>新增非IP網路，即串列埠心跳網路

Extended Configuration>Extended Topology Configuration>

Configure HACMP Networks>Add a Network to the HACMP Cluster

選擇RS232，新增串列埠心跳。（自動獲取網路名和型別）

<4>新增IP地址（HACMP IP地址和串列埠地址）即網路介面和，心跳或磁碟裝置

Extended Configuratin>Extended Topology Configuration>

Configure HACMP Communication interfaces/Devices(HACMP通訊介面或串列埠裝置配置)

>Add Communication interfaces/Devices

新增串列埠裝置IP地址

Extended Configuratin>Extended Topology Configuration>

Configure HACMP Communication interfaces/Devices(HACMP通訊介面或串列埠裝置配置)

>Add Communication interfaces/Devices

Device Name 自己自定義名稱。如：hisser1_tty0

Device path 一般都是：/dev/tty0

Node name 選擇主機A作為NODE A，如圖就是hisser1

<5>新增對外IP 也就是服務IP即：server(新增資源組之前必須先新增服務IP，否則資源組就無法和SERVER IP繫結在一起)

Extended Configuration>Extended Resource Configuration>

HACMP Extended Resources Configuration>Configure HACMP server IP

Labels /Addresses >Add a Service IP Label/Address
