73 ZONE-1004 ZONE-1004 Message , [ZONE-1004], ,, INFO, , port enforcement changed to Session Based HARD Zoning. Probable Cause Recommended Action Severity Indicates that the zoning enforcement changed to session-based hard zoning. When a device is zoned using both WWN in one zone and in another, this will cause that port to go session based hard zoning. In session-based zoning, the zone enforcement is checked by the software. In hardware-enforced zoning, zone or alias members are defined using exclusively or using WWNs exclusively: that is, using one method or the other to define all objects in the zoning database. If the devices on the port are defined by a mixture of port IDs and WWNs, the zone enforcement is session based. If the S_ID list of the hardware-enforced zoning overflows (over the S_ID limit), the hardware zone enforcement changes to session-based zoning. No action is required. INFO ZONE-1005 Message , [ZONE-1005], ,, INFO, , HARD & SOFT zones(, ) definitions overlap. Probable Cause Recommended Action Severity Indicates that a port is zoned with mixed devices (WWN and ). During zoning database cross checking, it is detected that either: • A port zone member is also listed as a member of a Mixed zone, • A WWN zone member is also specified as a member of a Mixed zone. You should use hard zone enforcement whenever possible. Hard zones are more secure than "sessionbased hard zones". Both types of zones will trap a PLOGI, but hard zones will filter out the I/O frames which"session-based" hard zones do not. If hard zone enforcement is preferred, edit the zoning database to have the port zoned with devices defined as either WWN or defined as but do not mix the methods used to define these zone members.
