Adding an Initiator

Procedure

1. Choose Services > Block Service > Hosts.
2. On the Hosts tab page, click More on the right of the desired host and choose Add Initiator.

   The Add Initiator page is displayed on the right.

   Alternatively, perform either of the following operations to go to the Add Initiator page:

   • Click the name of the desired host. In the upper right corner of the page that is displayed, select Add Initiator from the Operation drop-down list.
   • Click the name of the desired host. On the page that is displayed, click the Initiators tab page, and then click Add.

3. Select initiators.
   1. Select an initiator type (FC or iSCSI) based on service requirements.
   2. Select one or more initiators from Available Initiators.

4. (Optional) Click Create Initiator. On the Create Initiator page that is displayed, set the related parameters.
   • If initiators have been configured on an application server:
     • When initiators can be automatically discovered on DeviceManager, skip this step.
     • When initiators cannot be automatically discovered on DeviceManager, create initiators using the IQNs or WWPNs of initiators configured on the application server.
   • If no initiator has been configured on an application server, configure initiators by following instructions in the "Configuring Connectivity" in the OceanStor Dorado Host Connectivity Guide for XXX and then add initiators on DeviceManager.
   • On DeviceManager, set or modify parameters of initiators manually created or automatically discovered based on the multipathing software and host operating system version. For details about recommended parameter settings in different scenarios, see "Configuring Multipathing" in the OceanStor Dorado Host Connectivity Guide for XXX. For iSCSI initiators, you need to set CHAP authentication parameters based on the security authentication plan.

   Table 5-32 describes the FC initiator parameters.

   Table 5-32 FC initiator parameters

   Parameter	Description
   WWPN	World Wide Port Name (WWPN) of the initiator. [Value range] A WWPN is a hexadecimal value that contains 16 characters. It can contain letters A to F (uppercase and lowercase) and digits 0 to 9. It cannot be all 0, all F, or all f.
   Alias	Alias of the initiator. [Value range] An alias can be left blank or contain up to 31 characters. The name can contain only letters, digits, periods (.), underscores (_), and hyphens (-).

   Table 5-33 describes the iSCSI initiator parameters.

   Table 5-33 iSCSI initiator parameters

   Parameter	Description
   IQN	iSCSI Qualified Name (IQN) of the iSCSI initiator. NOTE: The IQN of an initiator must be the same as the one on the application server. The IQN of an initiator must be unique. Do not configure the initiators of multiple application servers with the same IQN. [Value range] An IQN must contain 1 to 223 visible ASCII characters and start with a digit or letter.
   Alias	Alias of the iSCSI initiator. [Value range] An alias can be left blank or contain up to 31 characters. The name can contain only letters, digits, periods (.), underscores (_), and hyphens (-).
   CHAP	CHAP authentication includes Normal Authentication and Discovery Authentication options. If you enable CHAP, you must configure a CHAP name and password for the storage system and the same CHAP name and password on the application server. If you do not enable CHAP, you do not need to configure a CHAP name or password. NOTE: After changing the CHAP authentication password on the storage system, you must use the new password to configure the CHAP authentication again on the application server.
   Normal Authentication	Authentication mode in the process during which the target and initiator transmit data between each other after connections are set up. Authentication modes include: No authentication Unidirectional authentication The target authenticates the initiator. Bidirectional authentication The target and initiator authenticate each other.
   Discovery Authentication	Authentication mode in the process during which the target and initiator are setting up connections. Authentication modes include: No authentication Unidirectional authentication The target authenticates the initiator. Bidirectional authentication The target and initiator authenticate each other. NOTE: When Normal Authentication or Discovery Authentication is set to Bidirectional authentication, you need to specify the CHAP Name and Password, and confirm the password in both the Target Authenticates Initiator and Initiator Authenticates Target areas.
   CHAP Name	User name for CHAP authentication. NOTE: The name must contain 4 to 223 characters. The name can contain only letters, digits, and special characters (!"#$&%'()*+,-./:;<=>?@[\]^_`{|}~). The first character must be a letter or digit.
   Password	Password for CHAP authentication. NOTE: The password can contain 12 to 16 characters. The password must contain at least three types of characters among uppercase letters, lowercase letters, digits, and special characters (`~!@#$%^&*()-_=+|[{}];:<,.\>/? and spaces). The password must not be the same as the user name or the user name spelt backwards.
   Confirm Password	Password for CHAP authentication. [Value range] The value of Confirm Password must be consistent with that of Password.

   After you click OK, the new initiator is automatically added to the list on the right.

5. Click OK.

   Confirm your operation as prompted.
