虚拟化做的rac，发现原来加盘直接把sdb、sdc、sdd、sde加到asm里了，后面通过udev绑定的盘，增加到asm里就报错：

[DBT-30007]Addition of disks to disk group DATA failed

ORA-15032:not all alterations performed

0RA-15333: diek is not visible on client instance

或者：

SQL> alter diskgroup DATA add disk '/dev/asm-diskj';
alter diskgroup DATA add disk"/dev/asm-diskj';
*
ERROR at line 1:
ORA-15032: not all alterations performed
ORA-15075: disk /dev/asm-diskj is not visible on instance number 2
SOL>

检查发现通过udev生成的sdf的连接asm_diskf磁盘都显出来了：

通过修改asm_diskstring不要把新加的sdf、sdg、sdh、sdi显示出来，asm_diskstring设置为“/dev/sd[b-e],/dev/mapper/asm*”，再次添加磁盘成功。
