AIX邏輯卷管理

lspv :查看系統硬盤

lspv hdisk# :查看硬盤hdisk#的空間分配狀況

lsvg :查看系統VG

lsvg vg_name : 查看VG的空間分配狀況

lsvg -l vg_name: 查看VG中LV分配狀況以及對應的文件系統

df -k :查看文件系統使用狀況。

綜合這些，能夠大體算出系統硬盤已分配了多少空間，實際已經使用了多少空間。

建立邏輯卷

將ORACLE存放數據目錄對應lv lv_ora設置爲8G，經過bc計算

# bc

1024*8/512

16

對應的pp數分別爲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

二、建立邏輯卷

[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組，選擇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 +

按兩次enter後：

Command: OK stdout: yes stderr: no

Before command completion, additional instructions may appear below.

lv_ora

掛載lv到文件系統

# smitty fs

AIX默認是jfs 因此選擇JFS加強型

由於前面已經建立過lv因此咱們選擇在選定的lv上建立fs

接下來能夠使用F4選擇邏輯卷,避免手寫出錯
