1、# lspvhdisk0 00cb45e5678b2a2b rootvg activehdisk1 00cb45e500864dcc None hdisk2 None None 创建PV使设备能被系统使用给hdisk2分配一个PVID使 hdisk2可用# chdev l hdisk2 a pv=yeshdisk2 00cb45e5115f3a33 None其他相关命令# lspv hdisk2 物理卷详细信息# lspv -l hdisk2 物理卷上分配的逻辑卷信息# lspv -p hdisk2 物理卷上物理分区分布的情况# rmdev -l hdisk2 -d 从ODM库中彻底删除hdi

2、sk0# extendvg rootvg hdisk1 向卷组中加一个物理卷# migratepv -l lv01 hdisk0 hdisk1 把属于lv01的pp从hdisk0移动到hdisk1创建VG并使用上PV创建VG 使用hdisk2 # mkvg y mqvg d 6 s 8 hdisk2 mqvg为VG名，-d 6 表示最多包含6个物理卷， -s 8 pp为8m ， 包含物理卷为hdisk2。hdisk2 00cb45e5115f3a33 mqvg active# lsvg -l vgname 查看vg中包含的lv# lsvg -p vgname 查看vg中包含的pv# chvg

3、-ay vgname 系统启动时自动激活vg# chvg -an vgname 系统启动时不激活vg# extendvg vgname hdisk9 向卷组中加一个物理卷# reducevg datavg disk2 vg中删除一个物理卷，之前必须用rmlv删除该物理卷上的所有lv在VG上创建LV创建LV# mklv y lvname t jsf vgname 2020为该lv包含20个逻辑分区# lsvg l mqvgmqvg:LV NAME TYPE LPs PPs PVs LV STATE MOUNT POINTma jfs 20 20 1 open/syncd loglv00 jfsl

4、og 1 1 1 open/syncd N/A# lspv l lvname 查看lv的基本情况# lspv p hdisk2 查看pv上空间使用情况创建文件系统方法一 ：在LV上创建文件系统# crfs v jfs d lvname m /test# mount /test# lsvg -l mqvgma jfs 20 20 1 closed/syncd /testloglv00 jfslog 1 1 1 closed/syncd N/A方法二： 直接创建文件系统# crfs v jfs g vgname m /qing a size=100M# mount /qing直接创建文件系统，系统

5、会在底层创建该文件系统关联的LV# lsvg -l mqvg ma jfs 20 20 1 open/syncd /testlv00 jfs 13 13 1 open/syncd /qing# df -gFilesystem GB blocks Free %Used Iused %Iused Mounted on/dev/hd4 36% 13859 16% /dev/hd2 78% 39931 23% /usr/dev/hd9var 49% 7150 11% /var/dev/hd3 12% 143 1% /tmp/dev/fwdump 1% 6 1% /var/adm/ras/platfor

9、SUCCESSES- Filesets listed in this section passed pre-deinstall verification and will be removed. Selected Filesets - # ODM definitions for Array disk devices FILESET STATISTICS - 1 Selected to be deinstalled, of which: 1 Passed pre-deinstall verification - 1 Total to be deinstalledinstallp: bosboot

10、 verification starting. An error occurred during bosboot verification processing.解决方法：# cd /usr/sbin# cp bosboot # chmod w bosboot 为自己增加写的权限# vi bosboot = 添加 exit 0 到第二行保存（此处添加这行的目的是安装完跳过bosboot检查）然后再安装，装好之后最好将bosboot 再改回来注：安装的时候要改，卸载的时候也同样。安装好多路径软件后，可能暂时无法实现多路径功能显示不了updiskX,如： # lsdev -Cc diskhdisk

16、s? 选择 “yes” * INPUT device / directory for software /* SOFTWARE to install _all_latest + PREVIEW only? （install operation will NOT occur） no + COMMIT software updates? yes + SAVE replaced files? no + AUTOMATICALLY install requisite software? EXTEND file systems if space needed? OVERWRITE same or new

17、er versions? VERIFY install and check file sizes? Include corresponding LANGUAGE filesets? DETAILED output? Process multiple volumes? ACCEPT new license agreements? no + PREVIEW new LICENSE agreements? WPAR Management Perform Operation in Global Environment yes + Perform Operation on Detached WPARs no + Detached WPAR Names _all_wpars + Remount Installation Device in WPARs yes + Alternate WPAR Installation Device 再装 SSH安装包中的， 最后SSH安装其它的包.
