Fibre Channel Connection

Fibre Channel Connection

This section introduces how to establish logical connections between a remote storage system and a local storage system when Fibre Channel connection is adopted between the two storage systems.

Configuring a Heterogeneous Storage System

When using SmartVirtualization to centrally manage storage resources, configure the heterogeneous storage systems and establish mappings between the local storage system and heterogeneous storage systems, so that external LUNs can be identified on the local storage system.

After connecting to the local storage system, the heterogeneous storage system regards the local storage system as a host. Only after a mapping is established between external LUNs on the heterogeneous storage system and the host, the local storage system can identify the LUNs mapped from the heterogeneous storage system.

Configuration operations vary depending on heterogeneous storage systems. For details, see the related operation guide.

NOTE:

Comply with related configuration restrictions when configuring heterogeneous and local storage systems to ensure that SmartVirtualization can be used to take over LUNs from heterogeneous storage systems after the local storage system is connected to the heterogeneous storage systems. For details, see Configuration Restrictions.

Full Automatic Scanning for LUNs (Applicable to FC Connection)

Full automatic LUN scanning enables all LUNs of the heterogeneous storage systems that have been mapped to the local storage system to be connected to the local storage system.

Prerequisites

A heterogeneous storage device has mapped its LUNs to the local storage device.

Context

Full automatic scan is used to scan for the LUNs and links of heterogeneous devices only.

Procedure

  1. Log in to DeviceManager.
  2. Choose Data Protection > Remote Device.
  3. Click Full Automatic Scan.

    The Confirm dialog box is displayed. The scan may take tens of seconds.

  4. Click OK.

    The Full Automatic LUN Scan dialog box is displayed. The system starts to execute full automatic scanning. The LUNs mapped from the remote device to the local device are displayed on the Remote LUN tab page.

  5. Click Close.

Follow-up Procedure

If alarm "Incompatible Heterogeneous Array Connected to the System" is reported after this operation, contact Huawei technical support engineers to add the heterogeneous storage device to the whitelist.
