Caution

  • This action item is only displayed when the "Use "Add Host"" checkbox is selected for the "Function to Add Host" field in "Web GUI Settings". This checkbox is not selected (this function is not displayed) by default. Refer to the [Setup Subsystem Parameters] function for details.

  • Note that this function does not create a host group. The storage system also has a function that creates new host groups to register hosts as their members. Refer to the [Add FC Host Group] function for details.

  • Hosts that are registered with this function can belong to host groups. However, only one LUN group can be allocated to a combination of host and port when configuring host affinity.

  • Refer to "Configuration Guide -Server Connection-" for each OS type to assign an appropriate host response to the host that is to be registered. A host response has a recommended pattern which has been prepared for each OS type. Refer to "Recommended Patterns of Host Responses" for details. If an appropriate host response is not configured to the host, the path may not be switched correctly or the volume may not be recognized correctly.

Note

  • To change the FC host information, use the [Modify FC Host] function.

  • The host affinity setting can be specified for each FC host. Refer to the [Create Host Affinity] function for details.
