1、AIX在硬盘上做操作系统备份mksysback，备份rootvg说明：操作系统V6R1，系统中只有一个VGrootvg注意：smit的log在根目录下smit.log可以查看该文件便于查询故障，硬盘系统备份无法引导系统，需要配置NAM才能做恢复测试先用root账户登录系统l步骤1：lsvgrootvg检查评估rootvg大小，如下USEDPPS.#lsvgrootvgVOLUMEGROUP:rootvgVGIDENTIFIER:00c03cc9aa4906VGSTATE:activePPSIZE:256megabyte(s)VGPERMISSION:read/writeTOTALPPs

3、查系统文件系统那些还有足够空间存放备份文件df–g如下，若有必要扩空间#df-gFilesystemGBblocksFree%UsedIused%IusedMountedon/dev/hd40.500.3236%1303115%//dev/hd23.500.8177%4565820%/usr/dev/hd9var2.001.6916%92693%/var/dev/hd30.250.0965%1121%/tmp/dev/hd110.006.9531%501%/home/dev/hd11admin0.250.251%51%/admin/proc-----/proc/dev/hd10opt0

6、择Change/ShowCharacteristicsofanEnhancedJournaledFileSystem再选择你需要扩的LV的mountpoint比如我需要的/home先定位光标在UnitSize中按F4选择Gigabytes修改以G为单位在Numberofunits输入要把/home扩到多大比如11G就输入11按执行键执行，等运行完成确认执行结果正常Command:OKCOMMANDSTATUSCommand:OKstdout:yesstderr:noBeforecommandcompletion,additionalinstructionsmayappearbelow.

7、Filesystemsizechangedtodf–g命令查看确认/home空间已经扩展成功为11G#df-gFilesystemGBblocksFree%UsedIused%IusedMountedon/dev/hd40.500.3236%1303115%//dev/hd23.500.8177%4565820%/usr/dev/hd9var2.001.6916%92663%/var/dev/hd30.250.0965%1121%/tmp/de
