ZONE-1004
Message
Probable
Cause
Indicates that the zoning enforcement changed to session-based hard zoning. When a device is zoned
using both WWN in one zone and <domain, portarea> 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 <domain, portarea> 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.

Action
No action is required.
Severity INFO
ZONE-1005
Message
Probable
Cause
Indicates that a port is zoned with mixed devices (WWN and <domain, portarea>). 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 "session-
based 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.
Recommended
Action
If hard zone enforcement is preferred, edit the zoning database to have the port zoned with devices
defined as either WWN or defined as <domain, portarea> but do not mix the methods used to define
these zone members.
