FC port issue

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:

Oct 15 07:34:51 terumos-bckp-srv2 vmunix: Target path (class=tgtpath, instance=12) has gone online.  The target path h/w path is 0/2/1/1.0x100000e00244038d

...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

Hi,

You have previous messages telling target path has gone offline?

No, I don't think so... I'll check it

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