情况介绍：两台V490，一台(GW11)有两块盘，做了镜像，一台(GW01)有一块硬盘，有坏块，需更换\r\n两台机器硬件一致，应用软件一致，所以想着用dd的方法比较简单，结果发现还挺麻烦，5555555\r\n1、将新硬盘插入GW11进行dd:\r\ndd if=/dev/rdsk/c1t0d0s2 of=/dev/rdsk/c1t1d0s2 bs=65535k\r\n\r\n2、将硬盘插回GW01\r\n\r\nSunOS Release 5.9 Version Generic_118558-06 64-bit\r\nCopyright 1983-2003 Sun Microsystems, Inc.

number要改：\r\n/etc/lvm/mddb.cf:\r\n#metadevice database location file do not hand edit\r\n#driver minor_t daddr_t device id checksum\r\nssd 11 16 id1,ssd@w21000014c3aed3b6/d -2156\r\nssd 11 2064 id1,ssd@w21000014c3aed3b6/d -4204\r\n试着启动系统，又启不来，接着郁闷，唉。。。。。。\r\n有个兄弟发来一篇文章，哈哈，有救了，就是修改/kernel/drv/md.conf:\r\n# Begin MDD database info (do not edit)\r\nmddb_bootlist1=\"ssd:11:16:id1,ssd@w20000014c3aed3b6/d ssd:11:2064:id1,ssd@w20000014c3aed3b6/d\";\r\n# End MDD database info (do not edit)\r\n\r\n6、修改system文件：\r\nset md:mirrored_root_flag=1\r\n\r\n7、启动系统，sys-unconfig\r\n系统能起来，检查metadb，正常\r\nmetastat检查状态，正常\r\ndf -k，数据能读，应用程序能正常启\r\n8、增加metadb，完成镜像同步\r\nroot@GDSZ-PS-GW011-WAP08 # prtvtoc /dev/rdsk/c1t0d0s2 |
