asm信息检查：

asm执行添加磁盘，删除磁盘操作：

##############
alter diskgroup DATA add disk
'/dev/rhdisk15',
'/dev/rhdisk16',
'/dev/rhdisk17',
'/dev/rhdisk18';
 ALTER DISKGROUP DATA drop disk
'DATA_0000',
'DATA_0001',
'DATA_0002',
'DATA_0003';

alter diskgroup data  rebalance power 8;

##############
alter diskgroup ARCH add disk
'/dev/rhdisk19';
 ALTER DISKGROUP ARCH drop disk
'ARCH_0000';
alter diskgroup ARCH  rebalance power 8;

##############
alter diskgroup REDO01 add disk
'/dev/rhdisk20';
 ALTER DISKGROUP REDO01 drop disk

alter diskgroup REDO02 add disk

 ALTER DISKGROUP REDO02 drop disk
'REDO02_0000';
alter diskgroup REDO01  rebalance power 8;
alter diskgroup REDO02  rebalance power 8;

##################
alter diskgroup OCRVOTE add disk

alter diskgroup OCRVOTE  rebalance power 10;

同步完成检查磁盘信息：
