AIX5.3升级(补丁安装升级)

AIX5.3升级(补丁安装升级)app

1、查看补丁信息(以个人IBM小型机ps为例)ssh

(1)oslevel -s命令确认版本信息:ide

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

(2)还能够经过instfix -i |grep AIX_ML查看实际文件集状况: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

说明:补丁已经打到10而且打全,若是补丁没有打全(以5300-10为例)会显示:Not all filesets for 5300-10_AIX_ML were found. 操作系统

(3)若是补丁没有打全如5300-10还能够查看105300-10缺哪些文件文件:blog

# oslevel -rl 5300-10
ci

2、下载AIX5.3所需最新补丁(以补丁包5300-12为例)rpc

1.补丁下载地址:http://www-933.ibm.com/support/fixcentral/

2.补丁下载好后,将补丁包上传至小型机相应目录。(可经过FTP软件如:FlashFXP上传)

注意:2012年1月31号后下载须要先注册。

3、补丁安装。

一、查看升级前系统状态。

errpt  没有异常;
df –g  检查文件系统使用率没有超过80%或者未使用空间大小超过100M;
lsps –s  检查swap使用率,最好不要超过20%;
lsvg –l rootvg  没有看到stale的逻辑卷;
lsdev –Cc processor  看到CPU个数正确;
ifconfig –a  看到网卡状态为UP。
Lppchk -v   执行无异常

二、肯定系统正常后,制做系统级全备份 mksysb至磁带,

smit mksysb
     ----Backup Device or File
      选择【/dev/rmt0】
     等到屏幕显示OK后拿出磁带. 这时候, 系统备份完成。如图:
 

三、升级操做:

(1)中止AIX系统上的全部应用(down)。

(2)对主机上在这次系统补丁安装以前所安装的补丁做COMMIT操做

1)   以root用户登陆主机

2)   Smit commit

对主机在这次系统补丁安装以前的补丁进行commit操做:SOFTWARE name 选择all,PREVIEW only 选择no,COMMIT requistites 选择yes,EXTEND file system if space needed 选择yes,DETAILED output选择yes,回车。如图:

 

注意:如发现有fail等报错信息,请中止升级。

(3)以Preview方式预安装补丁,检查预安装结果

1)   以root用户登陆主机

2)   smit update_all

3)   INPUT device/directory for software中输入补丁文件的绝对路径;

4)   选择Preview预安装系统补丁:PREVIEW only 选择yes;COMMIT software updates选择yes,SAVE replaced files选择yes,DETAILED output选择yes,ACCEPT new license agreement选择yes,回车。如图:

 注意:检查是否有报错信息。

 

  (4)以Apply方式安装补丁,检查安装结果

1)以root用户登陆主机

2) cd到补丁存放目录

3) smit update_all

4) 安装系统补丁:REVIEW only 选择no;COMMIT software updates选择No,SAVE replaced files选择yes,DETAILED output选择yes,ACCEPT new license agreement选择yes,回车。

如图:

注意:检查是否有报错信息


(5)查看补丁安装状况。

lslpp -l |grep -i APPLIED |more 能够看到安装的系统补丁,状态为applied;
oslevel-r看到当前操做系统维护级别;

instfix –vi|grep –i ML|more 能够查看到已经安装的补丁

(6)通常状况AIX系统补丁安装不须要重启,但为保证系统的稳定性建议重启。

# shutdown -Fr(如下为重启信息)
