在GI安装完成后查看集群状态时发现，磁盘组状态不对

通过asmca界面来mount磁盘组也报错：
ORA-15032: not all alterations performed
ORA-15017: diskgroup "DATADG" cannot be mounted
ORA-15040: diskgroup is incomplete
根据网上的资料参考，查看一下两个节点的asm_diskstring参数：
节点1：
SQL> show parameter asm
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
asm_diskgroups string DATADG
asm_diskstring string /dev/oracleasm/disks
节点2：
SQL> show parameter asm
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
asm_diskgroups string DATADG
asm_diskstring string
发现节点2的参数为空
手动设置一下：
SQL> alter system set asm_diskstring='/dev/oracleasm/disks';
System altered.
SQL> alter diskgroup DATADG mount;
Diskgroup altered.
