Error 1006.0005 can appear on a Qlogic fibre channel switch when using ACL zones. If you don’t need ACL zones, then the easiest thing to do here is to swap the offending zone back to a soft zone. To do so, open the Qlogic Switch and use the Edit menu to select “Edit Zoning …” From the zone editor, right-click on the zone to change and click on Set Zone Type. From the Set Zone Type pop-up, click on the option for Soft. Save the zoning and provided that you can actually use soft zones you are done. Now, what if you can’t use soft zoning? In that case, I find that this error specifically comes up when you have a device in a soft and ACL-based zone. To rectify that, either switch the soft zone to ACL or define the port in the ACL zone and the WWN in the soft zone.
