本文介紹了在AIX操做系統上如何卸裝已安裝配置好的HACMP軟件。node
在使用後面的步驟卸裝HACMP軟件以前,收集全部下面命令執行後的輸出,以肯定HACMP軟件中定義了哪些資源。網絡
(1)# usrsbinclusterutilitiescllsif 或者 # usressbinclusterutilitiescllsifui
(2)# usrsbinclusterutilitiesclshowres 或者 # usressbinclusterutilitiesclshowresthis
(3)# usrsbinclusterutilitescllsserv 或者 # usressbinclusterutilitescllsservspa
(4)# usrsbinclusterutilitiescllscustom 或者 # usressbinclusterutilitiescllscustom操作系統
若是在usrsbincluster或者usressbincluster目錄中有定製的事件,應用服務的啓動中止腳本或者是HA羣集的快照文件,那麼建議將這些文件移至另一個目錄,以保證在卸裝HACMP軟件時不會刪除掉這些文件。ssr
下面是卸裝HACMP軟件的具體步驟:3d
1.在每一個HACMP節點上以graceful方式中止掉HACMP服務:rest
a.以root用戶身份,運行smitty clstop命令,在兩個HACMP節點上以graceful方式中止掉HACMP服務。blog
# 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)
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
b.確認在HACMP中定義的全部資源,如IP標識、文件系統、卷組、應用服務等都已被中止。
c.以root用戶身份,運行lssrc -g cluster命令檢查HACMP軟件服務進程已被中止。
# lssrc -g cluster
Subsystem Group PID Status
2.以root用戶身份,運行smitty remove命令,刪除全部「cluster.」文件集。
(注意:若是是在非SP節點的AIX4.3.3的操做系統上,則也能夠刪除全部「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,設置每一個節點以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,設置每一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]

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,設置每一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,設置每一個節點所擁有的文件系統在系統啓動時自動被mount上。
# smitty chfs

6.若是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

7.配置應用服務在系統啓機時被啓動,例如,能夠在文件etcinittab中增長有應用服務啓動腳本的一行。
8.在每一個HACMP節點上,清除etchosts文件中再也不使用的有關boot地址標識的內容。
