asm磁盘normal模式（磁盘阵列normal模式）

在

NORMAL模式下磁盘组，可以设置3个失败磁盘组。

CREATE DISKGROUP data01 NORMAL REDUNDANCY

FAILGROUP controller1 DISK

'/dev/oracleasm/disks/ASMDISK1' NAME diska1,

'/dev/oracleasm/disks/ASMDISK2' NAME diska2

FAILGROUP controller2 DISK

'/dev/oracleasm/disks/ASMDISK3' NAME diska3,

'/dev/oracleasm/disks/ASMDISK4' NAME diska4

FAILGROUP controller3 DISK

'/dev/oracleasm/disks/ASMDISK5' NAME diska5,

'/dev/oracleasm/disks/ASMDISK6' NAME diska6

ATTRIBUTE 'au_size'='4M'

DG_NAME DG_STATE   TYPE       DSK_NO PATH  MOUNT_S FAILGROUP       STATE

--------------- ---------- ------ ---------- ------------------------------------------------------------ ------- -------------------- --------

DATA MOUNTED    NORMAL   0 /dev/oracleasm/disks/ASMDISK7  CACHED  DATA_0000       NORMAL

DATA MOUNTED    NORMAL   1 /dev/oracleasm/disks/ASMDISK8  CACHED  DATA_0001       NORMAL

DATA01 MOUNTED    NORMAL   0 /dev/oracleasm/disks/ASMDISK1  CACHED  CONTROLLER1       NORMAL

DATA01 MOUNTED    NORMAL   1 /dev/oracleasm/disks/ASMDISK2  CACHED  CONTROLLER1       NORMAL

DATA01 MOUNTED    NORMAL   2 /dev/oracleasm/disks/ASMDISK3  CACHED  CONTROLLER2       NORMAL

DATA01 MOUNTED    NORMAL   3 /dev/oracleasm/disks/ASMDISK4  CACHED  CONTROLLER2       NORMAL

DATA01 MOUNTED    NORMAL   4 /dev/oracleasm/disks/ASMDISK5  CACHED  CONTROLLER3       NORMAL

DATA01 MOUNTED    NORMAL   5 /dev/oracleasm/disks/ASMDISK6  CACHED  CONTROLLER3       NORMAL

可以使用容量：

333 NAME    TOTAL_MB FREE_MB      %USED

---------- ------------------------------ ---------- ---------- ----------

333 DATA 200     94 53

333 DATA01 600    360 40

当不指定失败组 使用默认方式建立：

每个磁盘默认是一个

FAILGROUP。

CREATE DISKGROUP data01 NORMAL REDUNDANCY disk

'/dev/oracleasm/disks/ASMDISK2' NAME diska2,

'/dev/oracleasm/disks/ASMDISK3' NAME diska3,

'/dev/oracleasm/disks/ASMDISK5' NAME diska5,

'/dev/oracleasm/disks/ASMDISK6' NAME diska6

ATTRIBUTE 'au_size'='4M'

333 NAME    TOTAL_MB FREE_MB      %USED

---------- ------------------------------ ---------- ---------- ----------

333 DATA01 600    360 40

图形方式建立 normal 磁盘中：

DG_NAME DG_STATE   TYPE       DSK_NO PATH  MOUNT_S FAILGROUP       STATE

DATA MOUNTED    NORMAL   0 /dev/oracleasm/disks/ASMDISK1  CACHED  DATA_0000       NORMAL

333 NAME    TOTAL_MB FREE_MB      %USED
