You might need to set MIHPTO using the FICONCUPSET command. The default is 180 seconds and it can be set using a channel command, presumably you have connection software doing this to set it to 0. The specifics are hardware dependent, for example Brocade directors. Don't casually change the configuration if you aren't intimately familiar with these commands.
