name server returns only those devices that are in the same zone as the initiator. Devices that are not
part of the zone are not returned as accessible devices.
Table 82 shows the various switch models, the hardware Zoning methodology for each, and tips for best
usage.

348 Administering Advanced Zoning
Methodology
Enables hardware-enforced Zoning
only on domain, port zones; WWN or
mixed zones are not
hardware-enforced. Any domain, port
zone that overlaps a mixed or WWN
zone is not hardware-enforced.
An overlap occurs when a member
specified by WWN is connected to a
port in a domain, port zone. The
domain, port zone loses its hardware
enforcement even though a review of
the zone configuration does not
indicate it.
Enable hardware-enforced Zoning on
domain, port zones, and WWN
zones. Overlap of similar zone types
does not result in the loss of hardware
enforcement. Overlap with other zone
type results in the loss of hardware
enforcement.
As in the HP StorageWorks 1 GB
switches, connecting a device
specified by WWN into a port
specified in a domain, port zone
results in loss of the hardware
enforcement in both zones.
Enable hardware-enforced Zoning
according to each switch type. Use the
portZoneShow command to find the
zone type to which a device is
attached.
Best practice
domain, port
Use identifiers. Do
not identify a zone member by its
WWN.
domain, port
Use either WWN or
identifiers.
domain, port
Use identifiers.
You can use WWN identifiers if
you place disk and tape targets
on 3000-series, and SAN Director
2/128 models, and do not use
domain, port
identifiers.
