Using QuickLoop Zones

Fabric Assist Zone Setup
Zoning commands with the prefix fazone that mirror other zoning commands
are: fazoneCreate, fazoneAdd, fazoneDelete, fazoneRemove,
and fazoneShow.
Private hosts are indicated within a fazone or alias by “H{}”. Within a single
fazone or alias, multiple initiators are detected during zone creation process.
CfgEnable can fail if multiple initiators are found in a single fazone.
Fabric Assist Zone Creation
The private host within a fazone has its own AL_PA domain space. A target that is
zoned with multiple hosts may be given different AL_PAs. A max of 125 unique
targets may be zoned with private hosts on any given switch.
Note: A fazone private host must be on a loop by itself. Sharing a loop with other
nodes will cause the fazone to fail.
Fabric Assist Operation
When “cfg” is enabled, AL_PAs are created for all zoned targets that are online,
on the private host's loop. The private host's loop is re-LIPed so that it may “see”
any added AL_PAs.
As additional targets join the fabric, if they are within the fazone, they will have an
AL_PA created on the private host's loop. This is triggered off of the RSCN. A
target may be zoned with one or more private hosts, and will have a unique
AL_PA created on each host's loop.
LIP Propagation
LIPs are propagated to all private devices within a fazone. They are not sent to
public targets in the fazone. LIPs are only sent when a fazone target comes online.
A loop of fazone targets that are re-LIPed, but do NOT add any new targets will
not propagate a LIP to any private hosts.
