Solaris硬盘分区结构

时间:2013年05月23日信息来源:不详 点击: 【字体:

Solaris下,一个磁盘包含8个分区,标记为0-7。此信息可以通过format命令,然后选择一个硬盘来看到,例如,在我自己的系统中(Solaris 9,Ultra 60),显示出来的信息如下:
# format
Searching for disks...done

AVAILABLE DISK SELECTIONS:
0. c0t0d0 <SUN18G cyl 7506 alt 2 hd 19 sec 248>
/pci@1f,4000/scsi@3/sd@0,0

selecting c0t0d0
[disk formatted]

partition>
不要看到内容这么多,就被吓住了,其实,format命令之后0. c0t0d0 <SUN18G cyl 7506 alt 2 hd 19 sec 248>/pci@1f,4000/scsi@3/sd@0,0所显示出来的含义很简单,0. c0t0d0就代表这台Ultra 60里面只装了一个硬盘(至于c0t0d0的具体含义,稍后会介绍),<SUN18G cyl 7506 alt 2 hd 19 sec 248>代表的是这个硬盘的大小和柱面信息,/pci@1f,4000/scsi@3/sd@0,0所代表的,就是这个硬盘的实际物理地址。这些信息看起来很复杂,其实一般都只需要看看format命令抓出来的硬盘数量,是不是我们装在系统上的数量,例如你装了两个硬盘,但是这里只有一个硬盘的信息,就需要认真面对了。
FORMAT MENU:
disk - select a disk
type - select (define) a disk type
partition - select (define) a partition table
current - describe the current disk
format - format and analyze the disk
repair - repair a defective sector
label - write label to the disk
analyze - surface analysis
defect - defect list management
backup - search for backup labels
verify - read and display labels
save - save new disk/partition definitions
inquiry - show vendor, product and revision
volname - set 8-character volume name
!<cmd> - execute <cmd>, then return
quit
format> p
这里所列出来的,是可以使用的命令,比如我在最下面format>,就是用了p这个命令(慢点,上面没有p这个命令啊?其实,这里p就是partition的简写),然后,列出了以下内容:
PARTITION MENU:
0 - change `0' partition
1 - change `1' partition
2 - change `2' partition
3 - change `3' partition
4 - change `4' partition
5 - change `5' partition
6 - change `6' partition
7 - change `7' partition
select - select a predefined table [next]
