mysql cluster data node freeze on phase 100 (no replies)

We recently change the datacenter of one node and the ip of the server. We configure ndb_mgmd config.ini(changed the ip).

When we start ndbd on the data node server it freeze on Phase 100:

ndb_mgm> all report memory;
Node 2: Data usage is 73%(23658 32K pages of total 32000)
Node 2: Index usage is 25%(9679 8K pages of total 38432)
Node 3: Data usage is 73%(23403 32K pages of total 32000)
Node 3: Index usage is 25%(9651 8K pages of total 38432)

ndb_mgm>

ndb_mgm> 3 status
Node 3: starting (Last completed phase 100) (mysql-5.1.47 ndb-7.1.5)

ndb_mgm>


How can we fix this problem? Thanks.
