Hello, I have the same problem. Using the db name instead of CURRENT SERVER at the first parameter makes no difference:
DB21034E The command was processed as an SQL statement because it was not a valid Command Line Processor command. During SQL processing it returned:
SQL0443N Routine "MMDBSYS.DB2IMAGE" (specific name "DB2IMAGEIMPORTF1") has returned an error SQLSTATE with diagnostic text "Can't connect to "IEV". ".
