AIX給oracle添加裸設備數據文件

平臺:AIX 5.3 單機 存在一個空閑磁盤hdisk1

總體思路：物理卷PV－>卷組VG－>邏輯卷LV（類型：raw）－>添加表空間

1.查看所有可用卷組

# lsvg -o

rootvg

2.創建ORACLE的卷組datavg

# smitty lvm

         Volume Groups

                    Add a Volume Group

                            Add an Original Volume Group

                                                                                      [Entry Fields]

  VOLUME GROUP name                                  [datavg]

  Physical partition SIZE in megabytes                64                     +

* PHYSICAL VOLUME names                              [hdisk1]                +

  Force the creation of a volume group?               no                     +

  Activate volume group AUTOMATICALLY                 yes                    +

    at system restart?

  Volume Group MAJOR NUMBER                          []                      +#

  Create VG Concurrent Capable?                       no                     +

  # lsvg -o

datavg

rootvg

3.對datavg創建lvdata002裸設備

創建裸設備

# mklv -t raw -y lvdata002 -a e -e x -o y datavg 10

lvdata002

-e x設置裸設備劃分到多盤

分配10個PP，即640M

# lsvg -l datavg

datavg:

LV NAME             TYPE       LPs     PPs     PVs  LV STATE      MOUNT POINT

lvdata002           raw        10      10      1    closed/syncd    N/A

該卷組1個邏輯卷（裸設備）未被使用（如果在顯示結果中closed/syncd狀態的邏輯卷）

賦予裸設備權限

# chown -R oracle:oinstall /dev/rlvdata*

# chown -R oracle:oinstall /dev/lvdata*

4.登陸ORACLE，給表空間USERS添加裸設備數據文件

SQL>  alter tablespace users add datafile '/dev/rlvdata002' size 100M; //SIZE 不能等于或大于LV值，裸設備名/dev/rlv*

Tablespace altered.

添加成功
