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. Use domain, port identifiers (PIDs). Do not identify a zone member by its WWN. 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. 4/8 SAN Switch, 4/16 SAN Switch, HP StorageWorks 2-GB switches, SAN Switch 4/32, Core Switch 2/64, SAN Director 2/128, and 4/256 SAN Director Mixed switches 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. Use either WWN or domain, port identifiers. 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. 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. Figure 6 shows a fabric with four non-overlap ping hardware-enforced zones. 182 Administering advanced zoning
