iSCSI Blade Server Configuration wizard

You can use the iSCSI Blade Server Configuration wizard to configure iSCSI initiators and iSCSI targets, map initiators to targets, and save the data in an XML format.

iSCSI Target Configuration

Use this page to define the iSCSI targets that exist in your environment.
Target Description
Type a descriptive name for the iSCSI target that you are configuring to receive storage requests.
IP Address
Type the IP address of the iSCSI target, for example, 192.121.201.96.
TCP Port
Type the four-digit port number that identifies the iSCSI target, for example 3260.
Boot LUN Number
Type the logical unit number (LUN) from which your iSCSI target will boot.
Target IQN
Type the iSCSI Qualified Name (IQN) for the iSCSI target. The IQN can be in IQN format or EUI format. IQN format shows the address with a leading iqn prefix followed by a naming identifier, for example: iqn.this_is_my_node. EUI format is a 16-character hexadecimal value with the leading prefix of eui, for example: eui:0123456790ABCDEF.
Configure Target Security
When this check box is selected, you can configure security settings for the iSCSI target.
Add/Update
Adds a new iSCSI target and its associated configuration information to the list of iSCSI targets, or updates the configuration information for an existing target that you have selected from the list and edited.
Remove
Deletes the selected iSCSI target from the list of iSCSI targets.

Target Security Configuration

Use this page to configure security for your iSCSI targets.
Security Type
You can select from the following types of security to implement for your iSCSI target:
None
No security is defined. This is the default option.
One way
The target authenticates the initiator.
Mutual
The initiator authenticates the target, and the target authenticates the initiator.
CHAP ID
Type the Challenge Handshake Authentication Protocol (CHAP) identifier to be used for iSCSI communication. The CHAP ID can have up to 16 ASCII characters.
Password
Type the password that corresponds to the CHAP ID.
Confirm Password
Reenter the password to verify accuracy.
Update
Allows you to update the security settings for an iSCSI target that is selected in the list.

Initiator Configuration - All DHCP

Use this page to configure the DHCP initiators that exist in your environment.
Description
Type a description of the iSCSI Dynamic Host Control Protocol (DHCP) initiator that you want to configure.
Hardware Initiator
When this check box is selected, it indicates that the DHCP initiator is hardware initiator rather than a software initiator.
ID for Parameter Acquisition
Select the client ID from which IP parameters are obtained on the DHCP server. You can choose from the following options:
Ethernet MAC
When this option is selected, the IP parameters are obtained from the Ethernet MAC address. This is the default option.
Note: If you have a Windows® DHCP server, select this option. Windows DHCP servers only support client identification using the Ethernet MAC address.
Scope/vendor ID
When this option is selected, the IP parameters are obtained from the Scope/vendor ID.
Client Alternate ID
When this option is selected, the IP parameters are obtained from the Client Alternate ID.
Client ID for Parameter Acquisition
This Client ID is an optional address used to further identify the DHCP service from which parameters are acquired.
DHCP Vendor Specific
When this check box is selected, you can specify a distinct scope/vendor ID from which the IP parameter information for the iSCSI DHCP initiator can be obtained.
Scope/Vendor ID
Optional: Type the Scope ID or the Vendor ID of the DHCP server from which IP parameter information for the iSCSI DHCP initiator should be obtained. This field is optional, but provides more specific information for obtaining IP parameters.
Configure DHCP Security and IP
When this check box is selected, you can customize security and internet protocol for your DHCP server.
Add/Update
Adds a new iSCSI DHCP initiator and its associated configuration information to the list of DHCP initiators, or updates the configuration information for an existing DHCP initiator that you have selected from the list and edited.
Remove
Deletes the selected iSCSI DHCP initiator from the list of iSCSI DHCP initiators.

Initiator Configuration - Customize DHCP Security and IP

Use this page to customize the security settings and IP parameters for DHCP initiators; you can choose to override settings that may exist on the DHCP initiator.
VLAN ID
If the DHCP server is on a virtual LAN (VLAN), type the VLAN identifier. The VLAN ID allows the initiator to access the iSCSI parameters from the DHCP server on the VLAN.
CHAP ID
Type the Challenge Handshake Authentication Protocol (CHAP) identifier to be used for iSCSI communication. The CHAP ID can have up to 16 ASCII characters.
Password
Type the password that corresponds to the CHAP ID.
Confirm Password
Reenter the password to verify accuracy.
Customize IP Settings
When this check box is selected, you can define specific IP settings for the iSCSI initiator.
Discovery IP Address Usage
Select the type of discovery service that iSCSI initiator should use. You can choose from the following options:
DHCP Server
Indicates that a DHCP server will be accessed by the discovery IP address. This is the default option.
SLP Server
Indicates that a Service Location Protocol (SLP) server will be accessed by the discovery IP address.
iSNS GUI: Server
Indicates that an Internet Storage Name Service (iSNS) service will be accessed by the discovery IP address.
IP Address
Type the IP address of the iSCSI initiator.
Discovery IP Address
Optional: Type the IP address of the specific DHCP server from which you want to access iSCSI parameters. This is an optional field that allows you additional control during discovery.
Update
Allows you to modify the security settings for the selected iSCSI initiator.

Initiator Configuration - All Parameters in VPD

Use this page to define iSCSI VPD initiators.
Description
Type a meaningful name for the iSCSI VPD initiator.
IP Address
Type the IP address of the iSCSI initiator.
Initiator IQN
Type the iSCSI Qualified Name (IQN) for the iSCSI initiator. The IQN can be in IQN format or EUI format. IQN format shows the address with a leading iqn prefix followed by a naming identifier up to 68 characters, for example: iqn.this_is_my_node. EUI format is a 16-character hexadecimal value with the leading prefix of eui, for example: eui:0123456790ABCDEF.
