我没有SUN的小型机。这是用的X86的服务器，以下内容不保证在Solaris Sparc的版本下好用。
df添加新硬件后有以下几种办法让系统识别新硬件
touch /reconfigure ; sync 重启电脑
在系统的启动过程当中根据系统提示按ＥＳＣ进入交互启动模式，添加硬件
不重启而让系统识别顺序输入如下命令
modunload -i 0
drvconfig
devlinks
disks
接下来为硬盘分区
# format 说明：-e 选项可以打开expert级菜单，比如可以进行写缓存的设置

分区完成后，分区名为硬盘名加s加你选的分区数。
如：硬盘1为 c0d1 0号分区为 c0d1s0
建立文件系统也就是格式化
# newfs /dev/dsk/c0d1s0 // 也可以使用newfs -N /dev/dsk/c1d1s0先预览下
newfs: 建构新的文件系统 /dev/rdsk/c1d1s0: (y/n)？ y
警告：inode 块 /柱面组 (115) > = 最后一个柱面组中的数据块 (63) 。
此表明 1008 扇区不能分配。
/dev/rdsk/c1d1s0: 在 208 磁道上，16 扇区的 63 柱面的 209664 扇区
102.4MB 在 13 柱面群组 (16 c/g, 7.88MB/g, 3776 i/g)

FREE BLK COUNT(S) WRONG IN SUPERBLK
SALVAGE? yes
2 files, 9 used, 98462 free (14 frags, 12306 blocks, 0.0% fragmentation)
另外我们编辑/etc/vfstab文件，使系统每次启动自动挂载文件系统
当文件系统顺坏的时候可以使用fsck进行修复，注意fsck只能修复例如超级块顺坏，inode同时存在于空闲和使用链表中这类结构性的数据损坏。
