本文介紹了在AIX操作系統上如何卸裝已安裝配置好的HACMP軟件。
在使用後面的步驟卸裝HACMP軟件之前，收集所有下面命令執行後的輸出，以確定HACMP軟件中定義了哪些資源。
（1）# usrsbinclusterutilitiescllsif 或者 # usressbinclusterutilitiescllsif
（2）# usrsbinclusterutilitiesclshowres 或者 # usressbinclusterutilitiesclshowres
（3）# usrsbinclusterutilitescllsserv 或者 # usressbinclusterutilitescllsserv
（4）# usrsbinclusterutilitiescllscustom 或者 # usressbinclusterutilitiescllscustom
如果在usrsbincluster或者usressbincluster目錄中有定製的事件，應用服務的啓動停止腳本或者是HA羣集的快照文件，那麼建議將這些文件移至另外一個目錄，以保證在卸裝HACMP軟件時不會刪除掉這些文件。
下面是卸裝HACMP軟件的具體步驟：
1.在每個HACMP節點上以graceful方式停止掉HACMP服務：
a.以root用戶身份，運行smitty clstop命令，在兩個HACMP節點上以graceful方式停止掉HACMP服務。
# smitty clstop
Stop Cluster Services
Type or select values in entry fields.
Press Enter AFTER making all desired changes.
[Entry Fields]
Stop now, on system restart or both now +
BROADCAST cluster shutdown true +
Shutdown mode graceful +
(graceful, graceful with takeover, forced)

Esc+9=Shell Esc+0=Exit Enter=Do
b.確認在HACMP中定義的所有資源，如IP標識、文件系統、卷組、應用服務等都已被停止。
c.以root用戶身份，運行lssrc -g cluster命令檢查HACMP軟件服務進程已被停止。
# lssrc -g cluster
Subsystem Group PID Status
2.以root用戶身份，運行smitty remove命令，刪除所有“cluster.”文件集。
（注意：如果是在非SP節點的AIX4.3.3的操作系統上，則也可以刪除所有“rsct.”文件集。）
# smitty remove
Remove Installed Software
Type or select values in entry fields.
Press Enter AFTER making all desired changes.

3.以root用戶身份，運行smitty chinet命令，設置每個節點以service IP地址引導。
# smitty chinet
Change Show a Standard Ethernet Interface
Type or select values in entry fields.
Press Enter AFTER making all desired changes.
[Entry Fields]
Network Interface Name en0
INTERNET ADDRESS (dotted decimal) [9.16.3.21]

F1=Help F2=Refresh F3=Cancel F4=List
Esc+5=Reset Esc+6=Command Esc+7=Edit Esc+8=Image
Esc+9=Shell Esc+0=Exit Enter=Do
4.以root用戶身份，運行smitty chvg命令，設置每個節點所擁有的卷組在系統啓動時自動被激活。
# smitty chvg
Change a Volume Group
Type or select values in entry fields.
Press Enter AFTER making all desired changes.
[Entry Fields]
VOLUME GROUP name datavg

F1=Help F2=Refresh F3=Cancel F4=List
Esc+5=Reset Esc+6=Command Esc+7=Edit Esc+8=Image
Esc+9=Shell Esc+0=Exit Enter=Do
5.以root用戶身份，運行smitty chfs命令，設置每個節點所擁有的文件系統在系統啓動時自動被mount上。
# smitty chfs
Change Show Characteristics of a Journaled File System
5.以root用戶身份，運行smitty chfs命令，設置每個節點所擁有的文件系統在系統啓動時自動被mount上。
# smitty chfs
Change Show Characteristics of a Journaled File System
Type or select values in entry fields.
Press Enter AFTER making all desired changes.

6.如果系統中設置了網絡文件系統，那麼以root用戶身份，運行smitty nfs命令，設置定義的網絡文件系統在系統啓動時被共享出去或者是被mount上。
# smitty nfs
-- Network File System (NFS)
-- Change Show Attributes of an Exported Directory
Change Attributes of an Exported Directory

7.配置應用服務在系統啓機時被啓動，例如，可以在文件etcinittab中增加有應用服務啓動腳本的一行。
8.在每個HACMP節點上，清除etchosts文件中不再使用的有關boot地址標識的內容。
9.在每個HACMP節點上，如果.rhosts文件不再被需要，刪除該文件。
