AIX5.3升級(補丁安裝升級)

AIX5.3升級(補丁安裝升級)app

1、查看補丁信息(以個人IBM小型機ps爲例)ssh

(1)oslevel -s命令確認版本信息:ide

# oslevel -s
5300-10-04-1015
svg

(2)還能夠經過instfix -i |grep AIX_ML查看實際文件集狀況:ui

# instfix -i |grep AIX_ML
    All filesets for 5.3.0.0_AIX_ML were found.
    All filesets for 5300-01_AIX_ML were found.
    All filesets for 5300-02_AIX_ML were found.
    All filesets for 5300-03_AIX_ML were found.
    All filesets for 5300-04_AIX_ML were found.
    All filesets for 5300-05_AIX_ML were found.
    All filesets for 5300-06_AIX_ML were found.
    All filesets for 5300-07_AIX_ML were found.
    All filesets for 5300-08_AIX_ML were found.
    All filesets for 5300-09_AIX_ML were found.
    All filesets for 5300-10_AIX_ML were found.
spa

說明:補丁已經打到10而且打全,若是補丁沒有打全(以5300-10爲例)會顯示:Not all filesets for 5300-10_AIX_ML were found. 操作系統

(3)若是補丁沒有打全如5300-10還能夠查看105300-10缺哪些文件文件:blog

# oslevel -rl 5300-10
ci

2、下載AIX5.3所需最新補丁(以補丁包5300-12爲例)rpc

1.補丁下載地址:http://www-933.ibm.com/support/fixcentral/

2.補丁下載好後,將補丁包上傳至小型機相應目錄。(可經過FTP軟件如:FlashFXP上傳)

注意:2012年1月31號後下載須要先註冊。

3、補丁安裝。

一、查看升級前系統狀態。

errpt  沒有異常;
df –g  檢查文件系統使用率沒有超過80%或者未使用空間大小超過100M;
lsps –s  檢查swap使用率,最好不要超過20%;
lsvg –l rootvg  沒有看到stale的邏輯卷;
lsdev –Cc processor  看到CPU個數正確;
ifconfig –a  看到網卡狀態爲UP。
Lppchk -v   執行無異常

二、肯定系統正常後,製做系統級全備份 mksysb至磁帶,

smit mksysb
     ----Backup Device or File
      選擇【/dev/rmt0】
     等到屏幕顯示OK後拿出磁帶. 這時候, 系統備份完成。如圖:
 

三、升級操做:

(1)中止AIX系統上的全部應用(down)。

(2)對主機上在這次系統補丁安裝以前所安裝的補丁做COMMIT操做

1)   以root用戶登陸主機

2)   Smit commit

對主機在這次系統補丁安裝以前的補丁進行commit操做:SOFTWARE name 選擇all,PREVIEW only 選擇no,COMMIT requistites 選擇yes,EXTEND file system if space needed 選擇yes,DETAILED output選擇yes,回車。如圖:

 

注意:如發現有fail等報錯信息,請中止升級。

(3)以Preview方式預安裝補丁,檢查預安裝結果

1)   以root用戶登陸主機

2)   smit update_all

3)   INPUT device/directory for software中輸入補丁文件的絕對路徑;

4)   選擇Preview預安裝系統補丁:PREVIEW only 選擇yes;COMMIT software updates選擇yes,SAVE replaced files選擇yes,DETAILED output選擇yes,ACCEPT new license agreement選擇yes,回車。如圖:

 注意:檢查是否有報錯信息。

 

  (4)以Apply方式安裝補丁,檢查安裝結果

1)以root用戶登陸主機

2) cd到補丁存放目錄

3) smit update_all

4) 安裝系統補丁:REVIEW only 選擇no;COMMIT software updates選擇No,SAVE replaced files選擇yes,DETAILED output選擇yes,ACCEPT new license agreement選擇yes,回車。

如圖:

注意:檢查是否有報錯信息


(5)查看補丁安裝狀況。

lslpp -l |grep -i APPLIED |more 能夠看到安裝的系統補丁,狀態爲applied;
oslevel-r看到當前操做系統維護級別;

instfix –vi|grep –i ML|more 能夠查看到已經安裝的補丁

(6)通常狀況AIX系統補丁安裝不須要重啓,但爲保證系統的穩定性建議重啓。

# shutdown -Fr(如下爲重啓信息)
