182 Administering advanced zoning
Figure 6 shows a fabric with four non-overlap ping hardware-enforced zones.
Table 35 Enforcing hardware zoning
Fabric type Methodology Best practice
HP StorageWorks
1-GB switches
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.
Use domain, port identifiers
(PIDs). Do not identify a zone
member by its WWN.

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.
Use either WWN or domain,
port identifiers.
Mixed switches Enable hardware-enforced zoning
according to each switch type. Use
the
portZoneShow
command to
find the zone type to which a device
is attached.
Use domain, port identifiers.
You can use WWN identifiers if
you place disk and tape targets
on HP StorageWorks 2-GB
switches, Core Switch 2/64, and
SAN Director 2/128, and do
not use domain, port identifiers.
