140 Administering advanced zoning
Resolving zone conflicts
Zone conflicts can be resolved by saving a configuration file with the
configupload
command,
examining the zoning information in the file, and performing a cut and paste operation so that the
configuration information matches in the fabrics being merged.
After examining the configuration file, you can choose to resolve zone conflicts by using the
cfgclear
command followed by the
cfgdisable
command on the incorrectly configured segmented fabric,
followed by a
portdisable
or
portenable
command on one of the ISL ports that connects the
fabrics. This causes a merge, making the fabric consistent with the correct configuration. Table 22 lists
considerations for zoning architecture.
CAUTION: Be careful using the
cfgclear
command; it deletes the defined configuration.
Table 22 Considerations for zoning architecture
Item Description
Type of zoning: hard or
soft (session-based)
If security is a priority, HP recommends hard zoning.
Use of aliases The use of aliases is optional with zoning. Using aliases requires
structure when defining zones. Aliases aid administrators of zoned
fabric in understanding the structure and context.
Security requirements Evaluate the security requirements of the fabric. If additional security is
required, add HP Secure Fabric OS into the fabric.
Interoperability fabric If the fabric includes a third-party switch product, only WWN zoning
is supported. Other types of zoning, including QuickLoop, are not
supported.
QLFA zones Evaluate whether the fabric will have QuickLoop Fabric Assist (QLFA)
or QuickLoop (QL) in it, and consider the following items before
creating and setting up QLFA zones:
QuickLoop Zoning—QuickLoop/QuickLoop zones cannot run on
Fabric OS v4.1.0 or later. However, Fabric OS can manage (create,
remove, update) QL zones.
QuickLoop Fabric Assist—A switch running Fabric OS v4.1.0 or later
cannot have a Fabric Assist host directly connected to it. However,
such a switch can be part of a Fabric Assist zone if a Fabric Assist
host is connected to a compatible switch in the fabric.
Testing Testing a (new) zone configuration—Before implementing a zone, run
the Zone Analyzer from Advanced Web Tools to isolate any possible
problems. This is especially useful as fabrics increase in size.
