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
