To configure dynamic mapping (using the name option) for an iSCSI initiator, follow these steps:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# iscsi dynamic
initiator islb
switch(config)# iscsi dynamic
initiator deny
switch(config)# no iscsi dynamic
initiator islb
Static Mapping
With static mapping, an iSCSI host is mapped to a specific pWWN and nWWN. This mapping is
maintained in persistent storage and each time the iSCSI host connects, the same WWN mapping is used.
This mode is required if you use access control on the target device.
You can implement static mapping in one of two ways:
•
•
Tip
To configure static mapping (using the name option) for an iSCSI initiator, follow these steps:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# iscsi initiator name
iqn.1987-02.com.cisco.initiator
switch(config-iscsi-init)#
switch(config)# no iscsi initiator
name iqn.1987-02.com.cisco.initiator

User assignment—You can specify your own unique WWN by providing them during the
configuration process.
System assignment—You can request that the switch provide a WWN from the switch's Fibre
Channel WWN pool and keep the mapping in its configuration.
We recommend using the system-assign option. If you manually assign a WWN, you must
ensure its uniqueness (see the Cisco MDS 9000 Family NX-OS Fabric Configuration Guide for
more information). You should not use any previously assigned WWNs.
Purpose
Enters configuration mode.
Specifies iSLB dynamic initiator mode.
Disallows dynamic initiators from logging on to the
MDS switch.
Reverts to iSCSI mode (default).
Purpose
Enters configuration mode.
Configures an iSCSI initiator using the iSCSI name of
the initiator node. The maximum name length is
restricted to 223 alphanumeric characters. The
minimum length is 16.
Deletes the configured iSCSI initiator.
