Storrie added: "He has signed a long-term contract with the club and remains totally committed."
Redknapp, 61, signed a new contract at Fratton Park in October and is preparing to lead Portsmouth out at Wembley on Saturday for the FA Cup final against Cardiff.
The former West Ham, Southampton and Bournemouth manager turned down the chance to manager Newcastle earlier this season.
Redknapp was also arrested and bailed by Police investigating alleged corruption in football and he was angered by the dawn raid at his house.
But Storrie reiterated Redknapp's commitment to the club.
He said: "It's a joke, total rubbish. You just wonder whether these people have an agenda because it's doing us no good.
Harry is furious about this - we all are. It's a load of rubbish
Peter Storrie
"We are about to play the FA Cup final and people are coming out with this. It's hardly helping things. We don't need this at this moment.
"People should not believe any of it, though, it's complete and utter nonsense.
"Where these silly stories come from I have no idea. They are nonsense, just nonsense.
"Harry is furious about this - we all are. It's a load of rubbish."
