Modifying an Initiator

Procedure

1. Log in to DeviceManager.
2. Choose Provisioning > Host > Initiator.
3. Select the initiator whose properties you want to modify and click Properties.

   The Initiator Properties dialog box is displayed.

4. Modify the properties of the initiator. If the iSCSI initiator does not enable CHAP authentication, Table 5-14 lists related parameters. If the iSCSI initiator has enabled CHAP authentication, Table 5-15 lists related parameters. For non-iSCSI initiators, Table 5-16 lists related parameters.
   Table 5-14 iSCSI initiator parameters (CHAP authentication not enabled)

   Parameter	Description	Setting
   Alias	Alias of the initiator.	[Example] Initiator01
   Uses third-party multipath software	This parameter is only available after the initiator is added for the host successfully. Select Uses third-party multipath software to use multipathing software not developed by the device provider. In the HyperMetro scenario, configure ALUA as described in HyperMetro Configuration Guide for Huawei SAN Storage Using OS Native Multipathing Software. If LUNs have been mapped to the host before you enable or disable Uses third-party multipath software, restart the host after reconfiguration. If the host has installed UltraPath, do not need to enable Uses third-party multipath software.	[Example] Uses third-party multipath software
   Switchover Mode	Path switchover mode. The system supports the following three modes: common ALUA: This mode is selected when the OS of the host that connects to the storage system is SUSE, Red Hat 6.X, Windows Server 2012 (Emulex HBA), Windows Server 2008 (Emulex HBA), and HP-UX 11i V3. ALUA not used: This mode is selected when a host such as HP-UX 11i V2 does not support ALUA or the actual application scenario does not need ALUA. Special mode: This mode is selected when the OS of the host that connects to the storage system is VMware, AIX, Red Hat 7.X, Windows Server 2012 (QLogic HBA), and Windows Server 2008 (QLogic HBA). NOTICE: In HyperMetro scenarios, set this parameter with the guidance of Huawei technical support engineers and follow the requirements of HyperMetro Configuration Guide for Huawei SAN Storage Using OS Native Multipathing Software. NOTE: The type of initiator failover mode. Asymmetric logical unit access (ALUA) is a multi-target port access model. In a multipathing state, the ALUA model provides a way of presenting active/passive LUNs to a host, and offers a port status switching interface to switch over the working controller. For example, when a host multipathing program supporting ALUA detects a port status change on a controller that becomes faulty, the program will automatically switch subsequent I/Os to the other controller.	[Example] common ALUA
   Special mode type	This parameter must be configured if Switchover Mode is set to Special mode. The detailed requirements are as follows: Mode 0: The host and storage system must be connected using a Fibre Channel network. The OS of the host that connects to the storage system is Red Hat 7.X, Windows Server 2012 (using QLogic HBAs), or Windows Server 2008 (using QLogic HBAs). Mode 1: The OS of the host that connects to the storage system is AIX or VMware. In the HyperMetro scenario, HyperMetro is in load balancing mode. Mode 2: The OS of the host that connects to the storage system is AIX or VMware. In the HyperMetro scenario, HyperMetro is in local preferred mode. Mode 3: The OS of the host that connects to the storage system is Linux or Solaris. HyperMetro is in local preferred mode. NOTICE: In HyperMetro scenarios, set this parameter with the guidance of Huawei technical support engineers and follow the requirements of HyperMetro Configuration Guide for Huawei SAN Storage Using OS Native Multipathing Software.	[Example] Mode 0
   Path Type	In the HyperMetro scenario, the storage system supports two path switchover modes: Optimal Path and Non-Optimal Path. When HyperMetro is in load balancing mode, set Path Type for the initiators of both the local and remote storage systems to Optimal Path. Enable ALUA on both the host and storage systems. If the host uses the round-robin multipathing policy, it delivers I/Os to both storage systems in round-robin mode. When HyperMetro is in local preferred mode, set Path Type for the initiator of the local storage system to Optimal Path, and that of the remote storage system to Non-Optimal Path. Enable ALUA on both the host and storage systems. The host delivers I/Os to the local storage system preferentially. In the non-HyperMetro scenario, retain the default value Optimal Path.	[Example] Optimal Path
   Enable CHAP authentication	CHAP authentication includes Discovery and Normal authentication. If Enable CHAP authentication is selected, you must set CHAP name and Password for the storage system. In addition, you must set CHAP name and Password on the application server for it to access the storage system. If Enable CHAP authentication is not selected, you do not need to set CHAP name or Password for the storage system. NOTE: The CHAP authentication parameters are valid when the type of the initiator is iSCSI.	[Example] -
