Solaris硬盤分區(qū)簡介

Solaris下,一個磁盤包含8個分區(qū),標記為0-7 。此信息可以通過format命令,然后選擇一個硬盤來看到,例如,在我自己的系統(tǒng)中(Solaris 9,Ultra 60),顯示出來的信息如下:
# format
Searching for disks...done
AVAILABLE DISK SELECTIONS:
0. c0t0d0
/pci@1f,4000/scsi@3/sd@0,0
Specify disk (enter its number): 0
selecting c0t0d0
[disk formatted]
Warning: Current Disk has mounted partitions.
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
!

, then return
quit
format> p
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
modify - modify a predefined partition table
name - name the current table
print - display the current table
label - write partition map and label to the disk
!
- execute
, then return
quit
partition>不要看到內(nèi)容這么多,就被嚇住了,其實,format命令之后0. c0t0d0 /pci@1f,4000/scsi@3/sd@0,0所顯示出來的含義很簡單,0. c0t0d0就代表這臺Ultra 60里面只裝了一個硬盤(至于c0t0d0的具體含義,稍后會介紹),代表的是這個硬盤的大小和柱面信息,/pci@1f,4000/scsi@3/sd@0,0所代表的,就是這個硬盤的實際物理地址 。這些信息看起來很復雜,其實一般都只需要看看format命令抓出來的硬盤數(shù)量,是不是我們裝在系統(tǒng)上的數(shù)量,例如你裝了兩個硬盤,但是這里只有一個硬盤的信息,就需要認真面對了 。
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
!
- execute
, then return
quit
format> p
這里所列出來的,是可以使用的命令,比如我在最下面format>,就是用了p這個命令(慢點,上面沒有p這個命令啊?其實,這里p就是partition的簡寫),然后,列出了以下內(nèi)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
modify - modify a predefined partition table
name - name the current table
print - display the current table
label - write partition map and label to the disk
!
- execute
, then return
quit
partition>
OK,到這里,我們的目的也達到了,這些信息應該很清楚的證明了:Solaris下,一個磁盤包含8個分區(qū),標記為0-7 。后面的仍然是一些可以用到的命令,這些命令的具體含義,大家可以看命令后面的英文介紹,至于怎么使用,以后再說 。下面我們將進入今天的重點:
