使用磁盘克隆 AIX操作系统new.doc

一.磁盘克隆安装操作系统。1.操作系统环境。# oslevel -s6100-04-10-1119# bootlist -m normal -ocd0hdisk0 pathid=0ent0 speed=auto duplex=auto bserver=000.000.000.000 client=000.000.000.000 gateway=000.000.000.000# lspvhdisk0 00cc1ad4ef095bf0 rootvg active hdisk1 00cc1ad46aff307f None 2.使用alt_disk_install工具克隆磁盘。# alt_disk_install -OCB hdisk1+-+ATTENTION: calling new module /usr/sbin/alt_disk_copy.
