ioscan的一点问题
请问这里的第二列(I列)代表什么?
为什么相同的设备,两种设备文件类型的I会不一样?
另外,/dev/rdsk/c3t10d0s2的最后的s2到底是什么意思?
谢谢!

那如果是数据盘呢?
也会这么分吗?
其他的问题能也帮忙解答一下吗:
这个分区的概念是什么?
是对这个磁盘逻辑的划分区域了吗?
是根据什么来划分区域的大小和数量?
怎么划分的?
目的又是什么?
引导盘上的三个分区:s1引导区,s2OS区,s3诊断区

hpux 11.31的操作系统,persistent device (diskxx) 和 legercy device (cxtxdx) 的instance number 不一样。
s2是第二个分区,在persistent device 中叫p2
instance number 示列号
