光纤硬盘的DD及映像，讨论一下。

"installboot" command.


7) With root mounted under "/a" run the following commands to re-build

the devices tree :


drvconfig -r /a/devices -p /a/etc/path_to_inst


cd /devices

find . -print | cpio -pduVm /a/devices


disks -r /a

devlinks -r /a


NOTE: It is currently necessary to use both "drvconfig" and "find | cpio" due

to bugid 4161768, drvconfig does not work properly with socal disks.


Configure the "boot-device" parameter in the EEPROM using the

"luxadm set_boot_dev /dev/dsk/{root slice entry}" command.


9) Restore the other filesystems on that disk, or comment out the

entries for them from /a/etc/vfstab. At least you must have all the

Solaris filesystems (root, /var, /usr, /opt, etc.) recovered.

补充一点：
假如原有系统根盘采用disksuite做了映像的话，先在缺省引导盘上做1-9步，完毕后做以下步骤：
备份/etc/system，然后将里面的disksuite root信息、内核驱动信息全部删除干净。
* Begin MDD root info (do not edit)
forceload: misc/md_trans
forceload: misc/md_raid
forceload: misc/md_hotspares
forceload: misc/md_sp
forceload: misc/md_stripe
forceload: misc/md_mirror
forceload: drv/pcipsy
forceload: drv/glm
forceload: drv/sd
rootdev:/pseudo/md@0:0,10,blk
* End MDD root info (do not edit)
* Begin MDD database info (do not edit)
set md:mddb_bootlist1="sd:6:16 sd:6:1050 sd:6:2084 sd:14:16 sd:14:1050"
set md:mddb_bootlist2="sd:14:2084 sd:22:16 sd:30:16"
* End MDD database info (do not edit)


10、假如原有系统根盘采用disksuite做了映像的话，需要将disksuite映像配置信息清理掉
/etc/lvm/md.cf

10) Reboot the system from the recovered disk.
建议用reboot -- -r选项重启

12、假如原有系统根盘采用disksuite做了映像的话，正常启动后按照标准做法重新配置disksuite映像。
