Setting up a command device using Hitachi Device Manager - Storage Navigator (Optional)

Set up the command device using Device Manager - Storage Navigator with the information and procedures in the following sections. This procedure is used only if Toolbox provisioning is failing, or manual provisioning of the command device is chosen.

Creating a virtual volume on Device Manager - Storage Navigator

Create a virtual volume with Device Manager - Storage Navigator.

  1. Create LDEVs from a parity group.
  2. Create a storage pool.
  3. Create a virtual volume.
  4. Convert the virtual volume to a command device.

Before you begin

In a browser, navigate to storage systems on the Storage Navigator of the storage system. Check if one or more parity groups have been created in the internal storage. If they have, proceed with creating LDEVs from one of the parity groups.

Creating LDEVs from a parity group

Create LDEVs from a selected parity group to begin the process of creating a virtual volume for conversion to a command device.

  1. Create two LDEVs, each with equal and maximum capacity based off the parity group.

  2. In the left panel, select Logical Devices.

  3. In the center panel, select Create LDEVs.

  4. Complete the following steps using the default entries:

    1. Verify that the Provisioning Type is Basic.

    2. Under Parity Group Selection, select Select Free Spaces, then select an internal parity group.

    3. Create two LDEVs, and select the maximum capacity under LDEV Capacity.

    4. Under Format Type, select Quick Formatting.

  5. Click Add > Finish > Apply.

    LDEV creation can take some time.

Creating a storage pool

Create a storage pool of logical devices from physical parity groups.

  1. In the left panel, select Pools.

  2. In the center panel, select Create Pools.

  3. Complete the following substeps using the default entries:

    1. Select the Provisioning Type as Dynamic Provisioning.

    2. Disable Multi-Tier Pool.

    3. Under Pool Volume Selection, click on Select Pool VOLs. Choose one of the LDEVs that was provisioned in the previous procedure, select Add, and click OK.

    4. Select an appropriate name for the storage pool.

  4. Click Add > Finish > Apply.

    Storage Pool creation can take some time.

Creating a virtual volume

A virtual volume carved out of the previously created storage pool is eventually converted to a command device.

  1. In the left panel, expand Pools and select the Storage Pool.

  2. In the center panel, select Virtual Volumes.

  3. Complete the following substeps using the default entries:

    1. Set the Provisioning Type to Dynamic Provisioning.

    2. Set LDEV Capacity to a small size: 50 MB.

    3. Enter an appropriate name for the virtual volume.

  4. Click Add > Finish > Apply.

    Virtual volume creation can take some time.

Creating Fibre Channel zones

You can create fibre channel zones from the UCP Advisor UI. Alternatively, you can use the corresponding switch CLI commands.

The setup assumes two management hosts and two Fibre Channel switches connected to four storage ports; use the following diagram as reference.

  • HBA port 2 on each management host connects to two storage ports through Fibre Channel switch 2.

Procedure

  1. SSH into the Fibre Channel switch that connects the host to the storage array.

  2. Run switchshow to get information about what ports are connected and available to create zones around:

    1. Ports 0-31: Compute (Skylake) servers

    2. Ports 32-43: Storage

    3. Ports 44-47: Management hosts

  3. On the UCP Advisor user interface, perform the following steps:

    1. Add the Fibre Channel switches to the network inventory.

    2. Create a zone alias for each member in the setup for each switch. (Obtain WWN information from the result of switchshow, and map the port ID CLx-x using the Device Manager - Storage Navigator as reference.)

    3. Create a zone in each Fibre Channel switch with the following composition: two HBA ports and two storage ports.

  4. Enable the zone configuration on each switch using the switch CLI commands or on the UCP Advisor user interface.

    NoteZone creation on the UCP Advisor user interface currently does not automatically enable the zone configuration after successful zone creation.
  5. Using the switch CLI, perform the following steps:

    1. SSH into the Fibre Channel switch.

    2. Run zoneshow. If the newly created zone is visible under Effective configuration, stop here; otherwise, continue with the next steps.

    3. Create a new zone configuration that will hold information about the newly created zone: cfgcreate zone_config_name, zone_name.

    4. Enable the zone configuration created in the previous step: cfgenable zone_config_name.

    5. Check if the zone is effective on the switch using: zoneshow.

  6. Create four host groups with the following composition:

    1. Host Group 1: Storage port 1 connected to Fibre Channel switch 1, HBA port 1 on host 1, HBA port 1 on host 2.

    2. Host Group 2: Storage port 2 connected to Fibre Channel switch 1, HBA port 1 on host 1, HBA port 1 on host 2.

    3. Host Group 3: Storage port 1 connected to Fibre Channel switch 2, HBA port 2 on host 1, HBA port 2 on host 2.

    4. Host Group 4: Storage port 2 connected to Fibre Channel switch 2, HBA port 2 on host 1, HBA port 2 on host 2.

    5. In a browser, navigate to Storage Systems on the Device Manager - Storage Navigator of the storage system.

    6. In the left panel, select Ports > Host Groups > iSCSI Targets.

    7. In the center panel, select Create Host Groups.

    8. Perform the following steps using the default entries:

      • Resource Group Name (ID) should be the same as that of the created command device.
      • Host Mode should be [21] VMware Extension.
      • Expand Host Mode Options and select Mode No. 54 and 63, then click Enable.
      • Select the Hosts and Ports based on the composition of the host group as described above.
    9. Click Add > Finish > Apply.

Presenting a command device to host groups

You can present a command device to host groups.

  1. In a browser, navigate to Storage Systems on the Device Manager - Storage Navigator of the storage system.

  2. In the left panel, select Ports > Host Groups > iSCSI Targets.

  3. In the main window, select the newly created host groups.

  4. In the center panel, select Add LUN Paths.

  5. In the wizard windows, select the created command device under Available LDEVs on the left.

  6. Click Add, then Next.

  7. Click Finish > Apply.

    This might take a few minutes.
  8. Verify if the operation was successful:

    1. Log in to the vCenter where the host was added.

    2. If you are using the vSphere web client, click the host in the left panel.

    3. In the center panel, click Configure > Storage Devices.

      The newly added command device should be visible in the list of devices.
  9. Add the device RDM to a VM.

    1. In the left panel on the vSphere web client, right-click the VM that requires an RDM of the command device.

    2. Click Edit Settings.

    3. At the bottom of the wizard window, near New Device, select RDM Disk, then click Add.

    4. Select the newly created Command Device and click OK to add the disk to the VM.

    5. Reboot the VM. If the VM is an Advisor Gateway VM, run puma_adm --ckstatus to verify that the command device is recognized by the Advisor Gateway VM.
