从安装硬盘到文件系统的相关命令

可以使用sam工具

 

ioscan -funC disk    查看硬盘信息
ioscan -funC tape    查看磁带信息

 

/dev/dsk/c1t5d0  
c表示card instance number 对应系统中的scsi卡
t表示target号 用于对应物理硬盘
d表示lun号 系统中看到的逻辑硬盘

 

#insf 配置新硬件，他会更新/etc/ioconfig和io_tree中的信息
#insf -e 去掉旧的硬件信息
#rmsf  /dev/dsk/c1t5d0  删除此硬件

 

pvdisplay -v

vgdisplay -v

lvdisplay -v

建pv：
#pvcreate /dev/rdsk/c0t0d1
#pvcreate -f /dev/rdsk/c0t0d1 如果磁盘以前属于其他vg，加f

建vg：
Create:
# mkdir /dev/vg01
# mknod /dev/vg01/group c 64 0x010000        --0x010000中的01表示vg号，是16进制数
# vgcreate vg01 /dev/dsk/c0t3d0 /dev/dsk/c0t4d0
Check:
# vgdisplay -v vg01
# pvdisplay -v /dev/dsk/c0t3d0
# pvdisplay -v /dev/dsk/c0t4d0

The options on vgcreate include：
-e max_physical_extents Sets the maximum number of physical extents per
   physical volume in a volume group (default is 1016).
-l max_logical_vols Sets the maximum number of logical volumes allowed
   in a volume group (default 255).
-p max_physical_vols Sets the maximum number of LVM disks (physical
   volumes) allowed in a volume group (default 16).
-s physical_extent_size Sets the size, in megabytes, for each physical extent in a
   volume group (default 4).

 

建lv：
Create:
# lvcreate -L 16 -n myswap vg01
# lvcreate -L 16 -n myfs1 vg01
# lvcreate -L 16 -n myfs2 vg01
Check:
# vgdisplay -v vg01
# lvdisplay -v /dev/vg01/myswap

Options
-L logical_volume_size The size of the logical volume in megabytes. The size
                       specified will be rounded up to the nearest whole
                       logical extent. The default is zero.
-l logical_extents_number The number of logical extents in the logical volume.
                          The default is zero.
-n name   A custom name you want to assign to the logicalvolume. The default name follows the naming convention.

To create a logical volume of 10 logical extents in size:
# lvcreate -l 10 /dev/vg01
To create a logical volume with a size of 100 MB:建一个100m的lv
# lvcreate -L 100 /dev/vg01
To create a logical volume with a nonstandard name:
# lvcreate -L 16 -n myswap vg01

 

建文件系统：
# mount -v   # reports which file systems are mounted where
# bdf        # also reports file system sizes, and other info

1. Create the new file system
# newfs -F hfs /dev/vg01/rmyfs1
2. Create a mount point directory for the file system
# mkdir /myfs1
3. Mount the new file system
# mount /dev/vg01/myfs1 /myfs1
4. Add the file system to the /etc/fstab file
# vi /etc/fstab
