使用卷管理工具对sun v250做镜像冗余

1、云南远程v250做raid1镜像内容介绍V250单机对系统盘和数据盘做镜像冗余，原来做了有四张盘，0号为系统盘，1 4 5 为数据盘，并做了条带为/dev/md/dsk/d20,要添加四块盘，一块做系统盘镜像，另外三块做卷d20的镜像d30。8盘磁盘名称：AVAILABLE DISK SELECTIONS: 0. c0tt0d00 /pcci11d,77000000/scssi44/sdd0,0 1. c0tt1d00 /pcci11d,77000000/scssi44/sdd1,0 2. c0tt2d00 /pcci11d,77000000/scssi44/sdd2,0 3. c0tt3d0
