7Zoning
Zoning defines the communication paths in a fabric. A zone consists of initiator and target ports in
the SAN. Ports can communicate only with other ports in their zone. However, ports can be
members of more than one zone. To zone devices in a fabric, the fabric’s principal switch must be
an HP switch and HAFM must discover and manage it.
HAFM performs zoning discovery once at startup, and thereafter once every two hours during
routine discovery. For best results, HP recommends that you perform zoning five discovery cycles
after starting the HAFM appliance.
The following zoning features are described:
• Zoning limits, page 157
• Zoning naming conventions, page 158
• Zoning configuration, page 158
• Zoning administration, page 166
Zoning limits
You can configure large zone sets with HAFM. Table 23 lists the zoning limits for the edge switches
and directors.
NOTE: Hard zoning is enforced when the firmware initializes. Devices not conforming to zoning
rules are restricted to their assigned zones.
