how to drop a db2 database that is in an inconsistent state I have a DB2 database that suffered a power outage in the storage array, its a test system I just want to kill it and rebuild.
db2 connect to mydb
SQL1015N  The database is in an inconsistent state.  SQLSTATE=55025

db2 drop db mydb
SQL1035N  The operation failed because the specified database cannot be
connected to in the mode requested.  SQLSTATE=57019

db2 restart db mydb
SQL1015N  The database is in an inconsistent state.  SQLSTATE=55025

db2stop
SQL1025N  The database manager was not stopped because databases are still active.

db2 backup db mydb to /dev/null
SQL1015N  The database is in an inconsistent state.  SQLSTATE=55025
Since the database seem to be of no value, you can try:
db2stop force
ipclean
db2start
db2 drop database mydb
