oracle ASM磁盘组操作常用语句

查询磁盘状态
set linesize 1000 pagesize 1000
col name for a20
col path for a30
col group_number for 9999
select name,path,group_number from v$asm_disk_stat ;

NAME PATH GROUP_NUMBER

DATADG_0003 /dev/sdh1 2
DATADG_0002 /dev/sde1 2
DATADG_0001 /dev/sdc1 2

CRSDG_0002 /dev/sdg1 1
CRSDG_0001 /dev/sdf1 1
CRSDG_0000 /dev/sdd1 1

7 rows selected.

查询磁盘组可用空间大小（看USABLE_FILE_MB字段，这个是保证磁盘组能达到normal状态冗余的情况下的可用大小）
SQL> set linesize 1000 pagesize 1000
SQL> col name for a20
SQL> col path for a30
SQL> col group_number for 9999
SQL> select state,name,type,total_mb, free_mb,USABLE_FILE_MB from v$asm_diskgroup_stat;

MOUNTED CRSDG NORMAL 49140 48272 15946
MOUNTED DATADG NORMAL 409584 409288 102248
