Solaris 10 添加裸设备
1.添加磁盘
--添加完物理磁盘后在root用户下执行命令
1 #devfsadm #对新加设备进行在线识别和加载
2.分区

3 查看添加的slice的信息
3.1分片命名惯例
--对于每个一磁盘分片，通常以cxtxdxsx表示，其中c/t/d/s的含义如下：
--*C代表控制器标号。控制器位于主板上面，所谓控制器，就是控制，发出命令的器件。
--*T代表目标编号。 即分配给每个存储设备的一个唯一的硬件地址。
--*D代表磁盘编号。 这个数字反映的是目标位置上的磁盘号，即具体的磁盘
--*S代表分片编号。 通常从0～7，即分片的号码了
3.2 查看/dev/dsk/c2t2d0s1 （分区中，添加的主存储分片为1）
