7.1.9 iSCSI commands

If your iPBridge has been configured for iSCSI, default settings may be customized to your specifications using the CLI commands in this section.

Note

For iSCSI-configured iPBridge models only

iSCSIAlias

Provides a human-readable name assigned to the iPBridge. Aliases may be 1 to 64 characters long and may contain spaces if spaces are enclosed in quotation marks. Entering the set iSCSIAlias command with no alias parameter causes the alias to be removed.

Default: 0

Set syntax: set iSCSIAlias [Alias]

Requires a SaveConfiguration command

Get syntax: get iSCSIAlias

iSCSIChap

Enables/disables requiring CHAP (Challenge- Handshake Authentication Protocol) to be used for the iSCSI protocol. If Multiple Target mode has been enabled, a valid target name must be provided. If CHAP is enabled, the target requires the initiator to negotiate CHAP authentication using the CHAP secrets. An initiator may reject this negotiation.

Default:disabled

In single target mode

Set syntax: set iSCSIChap [enabled disabled]

Get syntax: get iSCSIChap In multiple target mode

Set syntax: set iSCSIChap [Target Name] [enabled disabled]

Get syntax: get iSCSIChap [Target Name]

An in CHAP secret is for authentication of the server to the iPBridge. The iPBridge can store up to 32 in secrets, each with a unique Account Name (optionally the Initiator Name) and secret pair. The Account Name can be 1 to 223 characters. Account Names are case sensitive. Account name can not be all.

An out chap secret is for authentication of the iPBridge to the rest of the network. There can only be one out secret. The account name is ignored for out secrets and defaulted to root.

In multiple target mode, you may use discovery to determine the Target Name.

In single target mode

Set syntax: set iSCSIChapSecret [in out delete] [Account Name] <Secret>

Get syntax: get iSCSIChapSecret [Account Name all]

In multiple target mode

Set syntax: set iSCSIChapSecret [Target Name discovery] [in out delete] [Account Name] <Secret> Get syntax: get iSCSIChapSecret [Target Name] [Account Name all]

iSCSIPortNumber

Specifies the port number whereby the iPBridge listens for iSCSI connections. The port number must be between 1024 and 65535 except for port 860.

Default: 3260

Set syntax: set iSCSIPortNumber [portnum] Requires a SaveConfiguration command Get syntax: get iSCSIPortNumber

iSCSIChapSecret

Specifies the incoming and outgoing passwords for iSCSI chap sessions. RestoreConfiguration default sets the CHAP secret passwords pair to default values.

Secrets are case sensitive, 12 (16 for Microsoft iSCSI initiator) to 32 characters, and cannot contain spaces. In and out secrets must be different.

When either secret is all 0s, iSCSI CHAP authentication is disabled. Additionally, an all ‘0’ secret can be configured by entering the iSCSIChapSecret command confirmation prompts with no parameters.

55

iSCSITarget

Creates/deletes an iSCSI target name. The target name acts as a suffix to the standard bridge iSCSI-qualified name. The target name may not exceed 24 characters. A newly-created target has one LUN, the iPBridge LUN, at LUN 0. If the target name already exists, this command does nothing. Multiple Target mode must be enabled to use this command. In verbose mode, overwriting a map requires secondary confirmation of the action.

Immediate command: iSCSI [Target Name] <delete>
