Zoning naming conventions
The naming rules for zone names, zone aliases, and zone configuration names vary with the type of
fabric. The following conventions apply:
• Names must start with an alphabetic character and may contain alphanumeric characters and
the underscore ( _ ) character.
• Names are not case-sensitive.
• Zone, alias, and configuration names cannot begin with “bfa_”,“red_”, “lsan_red_”, or
“d__efault__”. Zone configuration names cannot begin with “r_e_d_i_r_c__fg”. These prefixes
are reserved.
• Names cannot begin with a numeric character or a special character.
• The recommended character limit is 64 characters.
• Duplicate names are not allowed between zones, zone aliases, and zone configurations within
a zone database.
If you enter an invalid zone or zone configuration name, an error or warning message displays
depending on the type of fabric you are trying to zone.
Zoning and FICON
Session-based hardware enforcement is in effect if the zone has a mix of WWN and Domain,Port
members.
Session-based hardware enforcement is also in effect if a port is in multiple zones, and is defined
by WWN in one zone and by Domain,Port in another.
Session-based zoning enforcement is not recommended in a FICON environment.
When configuring a zone for FICON, ensure that all members of the zone, including members of any
zone aliases, are either all WWN or all Domain,Port members, but not a mix of both.
Zone database size
The supported maximum zone database size is 1 MB.
If the fabric contains only Backbone Chassis platforms, the supported maximum zone database
size is 2 MB.
Virtual Fabric considerations: If Virtual Fabrics is enabled, the sum of the zone database sizes on
all of the logical fabrics must not exceed the maximum size allowed for the chassis (1 MB).
The Professional Edition does not support large zone databases. In the Professional Edition, the
maximum size of the zone database without zone aliases is 32 KB. If the zone database contains
aliases, the maximum size is less than 32 KB.
