How Can I Restore the Link If a Link Between a Switch and an HP EVA8000 Fails to Resume After the Cable Between the HP EVA8000 and the Fibre Channel Switch Is Removed and Reinserted or the Switch Is Restarted?

How Can I Restore the Link If a Link Between a Switch and an HP EVA8000 Fails to Resume After the Cable Between the HP EVA8000 and the Fibre Channel Switch Is Removed and Reinserted or the Switch Is Restarted?

Question

How can I restore the link if a link between a switch and an HP EVA8000 fails to resume after the cable between the HP EVA8000 and the Fibre Channel switch is removed and reinserted or the switch is restarted?

Answer

A local storage system is connected to an HP EVA8000 storage system through a Fibre Channel switch. After the cable between the HP EVA8000 and the switch is removed and reinserted or the switch is restarted, the switch sends LIP-loop initialization frames (loop acknowledgement) to the HP EVA8000. However, the HP EVA8000 does not support the loop mode and therefore does not return a response message. As a result, the switch resets the link connected to the HP EVA8000. Afterwards, the HP EVA8000's port mode becomes abnormal intermittently and the link fails to resume.
On the HP EVA8000, set its port mode to Fabric for the link to resume.
NOTE:
Unless you have to, do not perform any of the following operations when links are normal:
  • Remove the optical fiber to a port.
  • Simulate intermittent port disconnection.
  • Restart switches.
