举例为Ultra10到Fire 280R之间的OS 转换，Ultra10为ide磁盘，Fire280R为光纤磁盘

Ultra10 分区如下：

 

 

将ultra10上每个分区完整的复制到280R上面。

 

步骤：

ultra10

共享出目录/data用于后面nfs挂载恢复之用。

       # vi /etc/dfs/dfstab

         share -F nfs /data

 

如果两者之间的磁盘大小规格一样使用下面规划分区表

# prtvtoc /dev/rdsk/c0t0d0s2 > ; /data/vtoc.dat

如果两者之间的磁盘大小规格不同，建议互相对照通过手动分区

 

按每个分区ufsdump

       # ufsdump -0f /data/0.dump       /dev/rdsk/c0t0d0s0

或者 # ufsdump -0f /data/0.dump       /

       # ufsdump -0f /data/3.dump /dev/rdsk/c0t0d0s3

或者 # ufsdump -0f /data/3.dump       /usr

       # ufsdump -0f /data/4.dump       /dev/rdsk/c0t0d0s4

或者 # ufsdump -0f /data/4.dump       /opt

       # ufsdump -0f /data/5.dump       /dev/rdsk/c0t0d0s5

或者 # ufsdump -0f /data/5.dump       /var

 

Fire 280R：

启动到单用户

       # boot cdrom -sw

       简单配置一个网卡地址用于挂接ultra10的共享目录

       # ifconfig eri0 xxx.xxx.xxx.xxx netmask 255.255.255.0 up

挂接ultra10的共享目录到本地mnt目录

       # mount -F nfs ultra10-ipaddress:/data /mnt

 

# format

       针对每个分区创建新的文件系统并依次挂接到/a

       # newfs /dev/rdsk/c1t0d0s0

# newfs /dev/rdsk/c1t0d0s3

       # newfs /dev/rdsk/c1t0d0s4

# newfs /dev/rdsk/c1t0d0s5

 

       # mount /dev/dsk/c1t0d0s0 /a

       进入/a目录依次恢复

       # cd /a

       # ufsrestore -rf /mnt/0.dump

       # umount /a

       重复以上步骤，将所有分区全部ufsrestore完毕为止。

 

修改相关设定：

       # mount / dev/dsk/c1t0d0s0 /a

       # vi /etc/vfstab

       修改主机名和ip地址

       # vi /etc/hosts

       # vi /etc/hostname.interface

(注意：如果两者网卡名不同，不需修改此文件)

       # vi /etc/netmasks

       # vi /etc/nodename

         vi /etc/net/ticlts/hosts

         vi /etc/net/ticots/hosts

         vi /etc/net/ticotsord/hosts

       设置启动块

       # cd /

       # installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk /dev/rdsk/c1t0d0s0

 

由于ultra10和280R机器类型不同，使用的设备树也不一样，需要通过更新设备树才能正常开机。否则有如下错误：
