From c0a4cbb74a59c0fe552d3128c8fe510dc23f3a7d Mon Sep 17 00:00:00 2001 From: Sawan Chandak Date: Thu, 9 Apr 2015 15:00:07 -0400 Subject: [PATCH] qla2xxx: Restore physical port WWPN only, when port down detected for FA-WWPN port. For FA-WWPN is enabled port, if NPIV created on that port and, if port link is brought down, then WWPN was restored from flash for both physical and NPIV port. This will result in NPIV port and physical port sharing same WWPN. Any application refreshing ports information will not be able to scan NPIV port because of this behavior. So while restoring WWPN, only restore physical port WWPN.
