Modify Host Group (iSCSI)

This function performs the following modifications to the existing iSCSI host group.

• Changing the "Host Group Name" settings

• Changing the "Host Response" allocation

• Changing the "Host" settings (including addition and deletion of member hosts in a host group)

Hosts can be added to host groups which the host affinity setting has been already configured, or deleted from host groups.

If a host is added, the host affinity setting is automatically configured to the host, as a host group member.

If a host is deleted, the host affinity setting is cleared from the corresponding host.

The Number of Hosts That Can Be Registered

*1

:

Total of all hosts, regardless of the interface type.

Availability of Executions in the Default Role

Host Group Setting

The following two methods are available for adding or deleting hosts from an existing iSCSI host group.

• Selecting the Target Hosts that Are to Be Added or Deleted from the List

• Manually Specifying the Target Hosts that Are to Be Added

Selecting the Target Hosts that Are to Be Added or Deleted from the List

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

Add an iSCSI host to a host group from the host list. Or delete an iSCSI host from the host group. After an iSCSI host has been added to a host group, the iSCSI host is named automatically. Refer to "Naming Conventions for Adding or Renaming 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 Target Hosts that Are to Be Added

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

To add a new iSCSI host that is not connected to the iSCSI port, directly enter the iSCSI host information. After the iSCSI host has been added to a host group, the iSCSI host is named automatically. Refer to "Naming Conventions for Adding or Renaming Hosts" for details.

Function Button

In this screen, change the iSCSI host group settings.

1. Select the iSCSI host group that is to be changed, and click [Modify Host Group] in [Action].

2. Enter a new host group name, or re-select a host response to be assigned to the host group.

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

   • Selecting the registration or deletion target host from the list

     2. Add or delete a host, and input the iSCSI host information (such as the IP Address and Alias Name) for the added host, and click the [Modify] button.

        Select the corresponding host checkbox in the iSCSI host list, to add a host.

        Clear the corresponding host checkbox in the iSCSI host list, to delete a host.

        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

          • 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.
