Add iSCSI Host Group

This function creates a new iSCSI host group and registers which hosts are members of this group.

A host group is a group of hosts (HBAs) that are allowed to access the volume (LUN group). The Host Affinity is specified for each host group.

The Number of Host Groups and Hosts That Can Be Registered

*1	:	Total of all host groups, regardless of the interface type.
*2	:	Total of all hosts, regardless of the interface type.

Availability of Executions in the Default Role

Refer to "User Roles and Policies" for details on the policies and roles.

Host Group Setting

The following two methods are available to register a host.

• Selecting the Registration Target Host from the List

• Manually Specifying the Registration Target Host

Selecting the Registration Target Host from the List

This screen is displayed when the [Now Connected] tab is clicked.

Select an iSCSI host to be registered in a host group, and enter the IP address and the Alias name. After registration, the iSCSI host is named automatically. Refer to "Naming Conventions for Adding Hosts" for details.

Function Description

Filter setting is a function used to display a list of only the iSCSI hosts meeting all the specified conditions.

No filtering is set by default. The following table shows conditions that can be specified.

Manually Specifying the Registration Target Host

This screen is displayed when the [Manual Input] tab is clicked.

To register a new host that is not connected to the iSCSI port, directly enter the iSCSI host information. After registration, the host is named automatically. Refer to "Naming Conventions for Adding Hosts" for details.

Function Button

In this screen, create an iSCSI host group and registers the host that is to be a member.

1. Click [Add iSCSI Host Group] in [Action].

2. Enter a host group name to be created, and select a host response to be assigned to the host group.

3. Add a host in the host group in the following procedures.

   • Selecting the registration target host from the list

     1. Click the [Now Connected] tab.

     2. Select the host that is to be registered from the iSCSI host list, input the iSCSI host information (such as the IP address and Alias name), and click the [Add] button.

        → A confirmation screen appears.

        Caution

        • If the iSNS server has not been configured in the [Modify iSCSI Port Parameters] function, the iSCSI host cannot be automatically acquired.

        • The following restrictions in the environment that is described below apply for the automatic acquirement of host information (*1) even when the iSNS server is specified.

          *1

          :

          "iSCSI Name", "IP Version", "IP Address", and "Alias Name"

          • When one of the following OSs is used and there are multiple hosts that have the same iSCSI name but different IP addresses, only the information of one host can be acquired.

            • Windows Server 2012

            • Windows Server 2012 R2

            • Windows Server 2016

            • Windows Server 2019

            • Oracle Solaris 10

          • When the host OS is Oracle Solaris 11, "IP Version" and "IP Address" cannot be acquired.

        • If the iSCSI host information is not displayed when clicking the [Rediscover] button, make sure that there is no error in the connection environment, such as the connection between the host and the switch, and the CA port settings of the storage system. If there is no error in the connection environment, contact the Support Department or manually specify the iSCSI host information.
