3. Before configuring iSER targets, configure NIC interfaces and run L2 and

RoCE traffic, as described in Step 7 on page 153.

4. For SLES 15 and SLES 15 SP1, insert the SLES Package DVD and install

the targetcli utility. This command also installs all the dependency packages.

# zypper install python3-targetcli-fb

5. Start the targetcli utility, and configure your targets on the iSER target

system.

Using iSER with iWARP on RHEL and SLES

Configure the iSER initiator and target similar to RoCE to work with iWARP. You

can use different methods to create a Linux-IO (LIO

™

) target; one is listed in this

section. You may encounter some difference in targetcli configuration in SLES 12

and RHEL 7.x because of the version.

To configure a target for LIO:

1. Create an LIO target using the targetcli utility. Issue the following command:

# targetcli

targetcli shell version 2.1.fb41

For help on commands, type 'help'.

2. Issue the following commands:

/> /backstores/ramdisk create Ramdisk1-1 1g nullio=true

/> /iscsi create iqn.2017-04.com.org.iserport1.target1

/> /iscsi/iqn.2017-04.com.org.iserport1.target1/tpg1/luns create /backstores/ramdisk/Ramdisk1-1

/> /iscsi/iqn.2017-04.com.org.iserport1.target1/tpg1/portals/ create 192.168.21.4 ip_port=3261

/> /iscsi/iqn.2017-04.com.org.iserport1.target1/tpg1/portals/192.168.21.4:3261 enable_iser

boolean=true

/> /iscsi/iqn.2017-04.com.org.iserport1.target1/tpg1 set attribute authentication=0

demo_mode_write_protect=0 generate_node_acls=1 cache_dynamic_acls=1

/> saveconfig

NOTE

targetcli versions are different in RHEL and SLES. Be sure to use the

proper backstores to configure your targets:

 RHEL uses ramdisk

 SLES uses rd_mcp
