To add a Fibre Channel device to an existing virtual target, use the iscsicfg --add command
with the -tgt and -t operands:
Once the iSCSI target configuration is committed to the configuration database, the iSCSI target will
be accessible to the iSCSI host during the discovery process.
Creating discovery domains and domain sets
Discovery domains are analogous to zones and discovery domain sets are analogous to zone sets.
When there are no discovery domain or discovery domain sets defined, then all the iSCSI hosts
have access to all iSCSI targets.
NOTE: Only IQNs can be used as an entry to establish access control.
A Fibre Channel feature, Default Zoning, disallows access to all hosts when cfgDisable and
cfgClear are run. iSCSI ports function the same way for any action based on default zoning. In
other words, if default zoning is on and cfgDisable and cfgClear are run, the iSCSI hosts are
also denied access to the iSCSI virtual targets irrespective of a discovery domain set defined. To
avoid this behavior, verify that default zoning is turned off. The discovery domain set is activated
only after a cfgEnable is performed.
NOTE: Neither the discovery domain nor the discovery domain set are deleted when you run
cfgDisable and cfgClear.
Creating discovery domains
A discovery domain provides the flexibility to define the host-to-target access as follows:
iscsicfg [--create | --show | --add | --delete | --clear] dd [-d DD
name] [–m DD_Members] args
To create a discovery domain, run the iscsicfg --create dd command with the -d and -m
operands using a comma to separate members:
:
Creating/enabling discovery domain sets
Once a discovery domain is created, it can be added to the discovery domain set to enable the
configuration. The discovery domain set contains discovery domains. More than one discovery
