Emulex 3.4 user manual Viewing or Changing Authentication Configuration, Changing Your Password

•Hash Priority - The priority of the two supported hash algorithms (MD5 and SHA1) that the driver (HBA) presents during the DH-CHAP authentication negotiation with the switch (default is MD5 first, then SHA1.)

Viewing or Changing Authentication Configuration

To view or change authentication configuration:

1.In the discovery tree, click the HBA.

2.Select the Authenticate tab. The Authenticate tab is displayed. (If the fields on this tab are greyed out (disabled) authentication has not been enabled at the driver level.)

3.If you wish, change configuration values and click Apply. You are prompted for the current password (local password) to validate the configuration change request. The verification request only appears if a local password has been defined for this HBA.

To return settings to the status before you started this procedure, click Restore before you click Apply. Once you click Apply, changes can not be cancelled.

To return all settings (the configuration) to the default configuration, click Defaults. Be careful as this also resets the password(s) to NULL for this configuration.

To initiate an immediate authentication, click Initiate Authentication. This request is sent to the driver, even if you have not made any changes to the setup.

Note: To successfully authenticate with the switch using DH-CHAP, you only need to set the configuration mode to enabled and set the local password. The local password must be set to the identical value as the switch for the DH-CHAP authentication to succeed.

Changing Your Password

1.Click Password on the Authenticate tab.

2.Select ASCII text or binary (Hex input) format.

3.Select local or remote password.

•Local password is used by the driver (HBA) when the HBA initiates authentication to the switch (typical use).

•Remote password is used by driver (HBA) when the switch authenticates with the HBA. The latter is only possible when bi-directional has been checked on the configuration.

4.Provide the current value for the password to validate the 'set new password' request (unnecessary if this is the first time the password is set for a given HBA).

Caution: Do not forget the password once one has been assigned. Once a password is assigned to an HBA, subsequent DH-CHAP configuration settings for that HBA including 'default configuration' or new passwords require you to enter the existing password to validate your request (i.e. no further changes can be made without the password).

Note: Additional help is available by clicking Help on the Set Password dialog box.
