Creating iSCSI Interfaces

Each physical Gigabit Ethernet interface on an IPS module or MPS-14/2 module can be used to translate
and route iSCSI requests to Fibre Channel targets and responses in the opposite direction. To enable this
capability, the corresponding iSCSI interface must be in an enabled state.
To enable iSCSI interfaces, follow these steps:
Step 1 Enable the required Gigabit Ethernet interface.
switch# config terminal
switch(config)# interface gigabitethernet 2/1
switch(config-if)# no shutdown
switch(config-if)# exit
switch(config)#
Create the required iSCSI interface and enable the interface.
Step 2
switch(config)# interface iscsi 2/1
switch(config-if)# no shutdown
Note iSCSI wizard automatically turns on the Dynamic FC target import.

Presenting Fibre Channel Targets as iSCSI Targets

The IPS module or MPS-14/2 module presents physical Fibre Channel targets as iSCSI virtual targets,
allowing them to be accessed by iSCSI hosts. It does this in one of two ways:
•
•
The IPS module or MPS-14/2 module does not import Fibre Channel targets to iSCSI by default. Either
Note
dynamic or static mapping must be configured before the IPS module or MPS-14/2 module makes Fibre
Channel targets available to iSCSI initiators.

Dynamic mapping—Automatically maps all the Fibre Channel target devices/ports as iSCSI
devices. Use this mapping to create automatic iSCSI target names.
Static mapping—Manually creates iSCSI target devices and maps them to the whole Fibre Channel
target port or a subset of Fibre Channel LUNs. With this mapping, you must specify unique iSCSI
target names.
Static mapping should be used when iSCSI hosts should be restricted to subsets of LUs in the Fibre
Channel targets and/or iSCSI access control is needed (see the
page 43-19). Also, static mapping allows the configuration of transparent failover if the LUs of the
Fibre Channel targets are reachable by redundant Fibre Channel ports (see the
Failover" section on page 43-59).
