lspv :查看系统硬盘

lspv hdisk# :查看硬盘hdisk#的空间分配情况

lsvg :查看系统VG

lsvg vg_name : 查看VG的空间分配情况

lsvg -l vg_name: 查看VG中LV分配情况以及对应的文件系统

df -k :查看文件系统使用情况。

综合这些,可以大致算出系统硬盘已分配了多少空间,实际已经使用了多少空间。

创建逻辑卷

将ORACLE存放数据目录对应lv lv_ora设置为8G,通过bc计算

# bc

1024*8/512

16

对应的pp数分别为16

lsvg rootvg

VOLUME GROUP: rootvg VG IDENTIFIER: 00f7569400004c0000000136a01b8877

VG STATE: active PP SIZE: 512 megabyte(s)

VG PERMISSION: read/write TOTAL PPs: 1116 (571392 megabytes)

MAX LVs: 256 FREE PPs: 790 (404480 megabytes)

LVs: 12 USED PPs: 326 (166912 megabytes)

OPEN LVs: 11 QUORUM: 1 (Disabled)

TOTAL PVs: 2 VG DESCRIPTORS: 3

STALE PVs: 0 STALE PPs: 0

ACTIVE PVs: 2 AUTO ON: yes

MAX PPs per VG: 32512

MAX PPs per PV: 1016 MAX PVs: 32

LTG size (Dynamic): 1024 kilobyte(s) AUTO SYNC: no

HOT SPARE: no BB POLICY: relocatable

2、创建逻辑卷

[tydic91:root:/]#smitty mklv

Add a Logical Volume

Type or select values in entry fields.

Press Enter AFTER making all desired changes.

按F4,列VG组,选择oradatavg

Add a Logical Volume

Type or select values in entry fields.

Press Enter AFTER making all desired changes.

[Entry Fields]

Logical volume NAME [lv_ora]

* VOLUME GROUP name rootvg

* Number of LOGICAL PARTITIONS [16] #

PHYSICAL VOLUME names [] +

Logical volume TYPE [jfs2] +

POSITION on physical volume middle +

RANGE of physical volumes minimum +

MAXIMUM NUMBER of PHYSICAL VOLUMES [] #

to use for allocation

Number of COPIES of each logical 1 +

partition

Mirror Write Consistency? active +

Allocate each logical partition copy yes +

on a SEPARATE physical volume?

RELOCATE the logical volume during yes +

reorganization?

Logical volume LABEL []

MAXIMUM NUMBER of LOGICAL PARTITIONS [512] #

Enable BAD BLOCK relocation? yes +

SCHEDULING POLICY for writing/reading parallel +

logical partition copies

Enable WRITE VERIFY? no +

File containing ALLOCATION MAP []

Stripe Size? [Not Striped] +

Serialize IO? no +

按两次enter后:

Command: OK stdout: yes stderr: no

lv_ora

挂载lv到文件系统

# smitty fs

clip_image001

AIX默认是jfs 所以选择JFS增强型

clip_image002

因为前面已经创建过lv所以我们选择在选定的lv上创建fs

clip_image003

接下来可以使用F4选择逻辑卷,避免手写出错

clip_image004

设置自动挂载

clip_image005
