添加新硬件后有以下几种办法让系统识别新硬件 touch /reconfigure ; sync 重启电脑 在系统的启动过程当中根据系统提示按ＥＳＣ进入交互启动模式，添加硬件 不重启而让系统识别顺序输入如下命令 modunload -i 0 drvconfig devlinks disks 接下来为硬盘分区 hZ.b8R?7590422 # format 说明：-e 选项可以打开expert级菜单，比如可以进行写缓存的设置 Searching for disks...done AVAILABLE DISK SELECTIONS: 0. c0d0 < DEFAULT cyl 17728 alt 2 hd 15 sec 63> /pci@0,0/pci-ide@7,1/ide@0/cmdk@0,0 1. c0d1 < DEFAULT cyl 2077 alt 2 hd 16 sec 63> /pci@0,0/pci-ide@7,1/ide@0/cmdk@1,0 2. c1d1 < DEFAULT cyl 1038 alt 2 hd 16 sec 63> /pci@0,0/pci-ide@7,1/ide@1/cmdk@1,0 Specify disk (enter its number): 2 selecting c1d1 Controller working list found [disk formatted, defect list found] FORMAT MENU: disk - select a disk type - select (define) a disk type partition - select (define) a partition table current - describe the current disk format - format and analyze the disk fdisk - run the fdisk program repair - repair a defective sector show - translate a disk address label - write label to the disk analyze - surface analysis defect - defect list management backup - search for backup labels verify - read and display labels save - save new disk/partition definitions volname - set 8-character volume name !< cmd> - execute < cmd> , then return quit format> fdisk No fdisk table exists.
