Sounds like it should based on your description.  You should make sure other media settings match, such as speed, etc.. While this may seem illogical on a 1G SFP, some devices have varying expectations of that, so sometimes "speed nonegotiate" is necessary.

If you are going from HP-HP to Cisco-HP, you may need to disable their transciever eeprom check on the Cisco side.
