If the server has iBFT (iSCSI Boot Firmware Table) support, the Initiator Name is completed
with the corresponding value in the IBFT, and you are not able to change the initiator name in
this interface. Use the BIOS Setup to modify it instead.The iBFT is a block of information
containing various parameters useful to the iSCSI boot process, including iSCSI target and
initiator descriptions for the server.
5 Use either of the following methods to discover iSCSI targets on the network.
Š
iSNS: To use iSNS (Internet Storage Name Service) for discovering iSCSI targets,
continue with “Discovering iSCSI Targets by Using iSNS” on page 126 .
Š Discovered Targets: To discover iSCSI target devices manually, continue with
“Discovering iSCSI Targets Manually” on page 126 .
Discovering iSCSI Targets by Using iSNS
Before you can use this option, you must have already installed and configured an iSNS server in
your environment. For information, see
Chapter 12, “iSNS for Linux,” on page 109 .
1
In YaST, select iSCSI Initiator , then select the Service tab.
2 Specify the IP address of the iSNS server and port.
The default port is 3205.
3 On the iSCSI Initiator Overview page, click Finish to save and apply your changes.
Discovering iSCSI Targets Manually
Repeat the following process for each of the iSCSI target servers that you want to access from the
server where you are setting up the iSCSI initiator.
1 In YaST, select iSCSI Initiator , then select the Discovered Targets tab.
2 Click Discovery to open the iSCSI Initiator Discovery dialog.
3 Enter the IP address and change the port if needed.
The default port is 3260.
4 If authentication is required, deselect No Authentication , then specify the credentials the
Incoming or Outgoing authentication.
5
Click Next to start the discovery and connect to the iSCSI target server.
6 If credentials are required, after a successful discovery, use Login to activate the target.
You are prompted for authentication credentials to use the selected iSCSI target.
7 Click Next to finish the configuration.
If everything went well, the target now appears in Connected Targets .
The virtual iSCSI device is now available.
8
On the iSCSI Initiator Overview page, click Finish to save and apply your changes.
9 You can find the local device path for the iSCSI target device by using the
lsscsi
command:
lsscsi
[1:0:0:0] disk IET VIRTUAL-DISK 0 /dev/sda
