Linux LUN rescan not working on AMS500

I followed the hdlm documentation exactly, and the new luns won't show up until the host is rebooted. I even tried the qlogic rescan tool and that didn't work either

I'm looking for the new lun by doing cat  /proc/scsi/qla2xxx/1  and 2

I'm suspecting that this has something to do with a setting on the AMS500, which is set up exactly as specified in the user guide. I'm suspecting this has something to do with LUN protection or the undocumented Host Group Security option under Access Mode in the hitachi storage navigator

This is really annoying because the server I'm trying to get these luns to show up on has more than a dozen active database instances, and I really don't feel like rebooting it and bringing down all services every time I need to add a lun

Any help greatly appreciated
