Chapter 2. Configure the Fujitsu ETERNUS device

Before you can define the Fujitsu ETERNUS device as a Block Storage back end, you need to configure storage pools and ports on the device first. Consult your device documentation for details on each step:

  1. Set up a LAN connection between the Controller nodes (where the Block Storage service is hosted) and MNT ports of the ETERNUS device.
  2. Set up a SAN connection between the Compute nodes and CA ports of the ETERNUS device.
  3. Log in to the ETERNUS device using an account with the Admin role.
  4. Enable the SMI-S of ETERNUS DX.
  5. Register an Advanced Copy Feature license and configure the copy table size.

  6. Create a storage pool for volumes. This pool will be used later in the EternusPool setting in Section 3.1, “Create Driver Definitions for Each Back End”.

    Note

    If you want to create volume snapshots on a different storage pool, create a storage pool for that as well. This pool will be used in the EternusSnapPool setting in Section 3.1, “Create Driver Definitions for Each Back End”.

  7. Create a Snap Data Pool Volume (SDPV) to enable Snap Data Pool (SDP) for the create a snapshot function.

  8. Configure storage ports to be used by the Block Storage service. Then:

    1. Set those ports to CA mode.

    2. Enable the host-affinity settings of those storage ports. To enable host-affinity, run the following from the ETERNUS CLI for each port: 

      CLI> set PROTO-parameters -host-affinity enable -port CM# CA# PORT

      Where: * PROTO defines which storage protocol is in use, as in fc (Fibre Channel) or iscsi. * CM# CA# refer to the controller enclosure where the port is located. * PORT is the port number.
