getconf DISK_SIZE /dev/lunname

lsblk 磁盘块---查询

sqlplus / as sysasm
set lin 200
col path for a50
select name,path,state,mount_status,header_status from v$asm_disk;

查看lun是否能加
ls -l rhdisk43

lsattr -El hdisk43|egrep "pvid|reserve_policy"

reserve_policy  no_reserve                       Reserve Policy                          True

加盘
切换到grid
sqlplus / as sysasm

alter diskgroup data add disk '/dev/rhdisk118','/dev/rhdisk119','/dev/rhdisk120','/dev/rhdisk121' rebalance power 5;

等待同步完成

select * from v$asm_operation;
select disk_number, state, name, total_mb, free_mb from v$asm_disk where group_number = 2;

查看rebalance情况：
select disk_number, state, name, total_mb, free_mb from v$asm_disk where group_number = 1;

alter diskgroup datadg rebalance power 5;
select * from v$asm_operation;

getconf DISK_SIZE /dev/hdisk* 看硬盘大小
