Add SAS Host

Overview

This function registers a new SAS host (HBA).

The total number of all the interface type hosts that can be registered in the storage system is 1024 (128 for the ETERNUS DX60 S5).

Caution

  • This function is supported in the ETERNUS DX60 S5/DX100 S5/DX200 S5.

  • 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 SAS 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 SAS host information, use the [Modify SAS Host] function.

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