Cisco MDS 9000 Family CLI Configuration Guide

OL-16184-01, Cisco MDS SAN-OS Release 3.x

Chapter 42      Configuring iSCSI

Configuring iSLB

Note

The VSAN identifier is optional if the target is online. If the target is not online, the VSAN 
identifier is required.

In addition, you can disable auto-zoning.

If you configure an IQN for an initiator target, then that name is used to identify the initiator target. 
Otherwise, a unique IQN is generated for the initiator target. 

To configure iSLB initiator targets, follow these steps:

Configuring and Activating Zones for iSLB Initiators and Initiator Targets

You can configure a zone name where the iSLB initiators and initiator targets are added. If you do not 
specify a zone name, the IPS manager creates one dynamically. iSLB zone sets have the following 
considerations:

Command

Purpose

Step 1

switch# 

config terminal

switch(config)#

Enters configuration mode. 

Step 2

switch(config)#

 islb initiator ip-address 

10.1.1.3

switch(config-islb-init)#

Configures an iSLB initiator using its IPv4 address 
and enters iSLB initiator configuration submode.

Step 3

switch(config-iscsi-islb-init)# 

target 

pwwn 26:00:01:02:03:04:05:06 

Configures the iSLB initiator target using a pWWN 
with auto-zoning enabled (default).

switch(config-iscsi-islb-init)# 

target 

pwwn 26:00:01:02:03:04:05:06 no-zone

Configures the iSLB initiator target using a pWWN 
with auto-zoning disabled.

switch(config-iscsi-islb-init)# 

target 

device-alias SampleAlias

Configures the iSLB initiator target using a device 
alias with auto-zoning enabled (default).

switch(config-iscsi-islb-init)# 

target 

device-alias SampleAlias fc-lun 0x1234 

iscsi-lun 0x2345

Configures the iSLB initiator target using a device 
alias and optional LUN mapping.

Note

The CLI interprets the LUN identifier value 
as a hexadecimal value whether or not the 

0x

 

prefix is included.

switch(config-iscsi-islb-init)# 

target 

device-alias SampleAlias iqn-name 

iqn.1987-01.com.cisco.initiator

Configures the iSLB initiator target using a device 
alias and an optional IQN.

switch(config-iscsi-islb-init)# 

target 

device-alias SampleAlias sec-device-alias 

SecondaryAlias

Configures the iSLB initiator target using a device 
alias and an optional secondary device alias.

switch(config-iscsi-islb-init)# 

target 

device-alias SampleAlias sec-pwwn 

26:01:02:03:04:05:06:07

Configures the iSLB initiator target using a device 
alias and an optional secondary pWWN.

switch(config-iscsi-islb-init)# 

target 

device-alias SampleAlias vsan 10

Configures the iSLB initiator target using a device 
alias and the VSAN identifier.

Note

The VSAN identifier is optional is if the 
target is online. If the target is not online, the 
VSAN identifier is required.

switch(config-iscsi-init)# 

no target pwwn 

26:00:01:02:03:04:05:06 

Removes the iSLB initiator target.
