在前次drop instance的时候，需要重新设置/etc/services对应的文件http://www.cndba.cn/hbhe0316/article/131424

To fix that I edited the /etc/services to have same range of ports reservaded to the node partitions from both hosts.

In both host I made the following in /etc/services:

DB2_db2dpf      20061/tcp
DB2_db2dpf_END  20064/tcp
db2c_db2dpf     25014/tcp
