利用一台机器的磁带,在另外一台配置相同机器上恢复

dn001
步骤: 1、先执行恢复的操作 (a) OK> boot cdrom -s --------------以维护模式启动 (b) # newfs /dev/rdsk/c0t0d0s0 (c) # mount /dev/dsk/c0t0d0s0 /a ----------注意这里和上面(b)的区别 (d) # cd /a (e) # nohup ufsrestore -rvf 192.168.0.2:/dev/rmt/0 ./ & -----恢复的参数要用rvf而不是xvf(本机没有磁带机,借用192.168.0.2的磁带机) (f) # rm restoresymtable 下面修改针对用disksuite做过镜像的磁盘: 2、/etc/vfstab -----------将MD信息给修改过来 3、/etc/hosts -------------将原来地址注释掉,新加IP地址 4、/etc/system --将其中用disksuite做镜像时加的MD删除掉 5、/etc/dumpadm.conf -------------修改其中的MD的选项 6、/var/spool/cron/crontabs -------------注意这个目录下的各个用户的定时执行文件 7、做光纤硬盘 --------------一般帖子上都没有介绍做这步 (a)# drvconfig -r /a/devices -p /a/etc/path_to_inst (b)# cd /devices (c)# find . -print | cpio -pduVm /a/devices .................................................. .................................................. .................................................. .................................................. .................................................. .................................................. ...... 0 blocks (e)# cd /a/devices (f)# disks -r /a (g)# devlinks -r /a 8、正常引导并全部做SDS(sun disksuite) # cd /usr/platform/sun4u/lib/fs/ufs # installboot bootblk /dev/rdsk/c1t0d0s0 --------------安装引导块 # luxadm set_boot_dev /dev/dsk/c1t0d0s0 --------------重新配置启动设备 Do you want to change boot-device to the new setting? (y/n) y # cd / ; umount /a # fsck -y /dev/rdsk/c1t0d0s0 ** /dev/rdsk/c1t0d0s0 ** Last Mounted on /a ** Phase 1 - Check Blocks and Sizes ** Phase 2 - Check Pathnames ** Phase 3 - Check Connectivity ** Phase 4 - Check Reference Counts ** Phase 5 - Check Cyl groups 107390 files, 18271015 used, 8553207 free (7927 frags, 1068160 blocks, 0.0% fragmentation) # reboot -- -r ----------第一次启动的时候最好用这个命令
