I'm facing some strange HP-UX behavior. I have a small SAN with one HP server, two Cisco SAN switches and one HP tape library connected. When I issues port reset, syslog shows the following:

...but when I run ioscan -m hwpath I didn't see any devices through this path:
I tried to run scsimgr replace_wwid command, scsimgr enable, but with no success... Library host access is properly configured. Any help or comments are greatly appreciated

I've just restarted the port on SAN. Take a look at the logs:
