    Deploying a single-SP UnityVSA

    Set up the VM environment for a single-SP UnityVSA

    Procedure
    1. Verify that the selected ESXi host meets the required configuration, as outlined in Requirements for installing a single-SP UnityVSA.
    2. Verify, and if necessary configure, the host network configuration.
    3. Verify that a vSphere switch has been created.
      1. Determine which port groups are associated with which subnets so you can ensure that the VM's network adapters are assigned to the correct subnet.
        • Ethernet port 0 is associated with network adapter 3.
        • Ethernet port 1 is associated with network adapter 4.
        • Ethernet port 2 is associated with network adapter 5.
        • Ethernet port 3 is associated with network adapter 6.

        You can verify which VM network adapter is mapped to which UnityVSA Ethernet port by comparing the MAC address displayed for the network adapter in the vSphere VM Hardware summary to the MAC address displayed for the Ethernet port in Unisphere.

        To display the MAC address in Unisphere, select System > System View > Enclosures. Select the rear view of the Disk Processor Enclosure (DPE) and click on an Ethernet port to display detailed information about the port, including its MAC address. It is important to take note of the Ethernet port name, for example, SPA Ethernet Port 3, since this is the port name used when creating iSCSI and replication network interfaces.

      2. If the network environment supports jumbo frames, verify that the MTU value for the switch on the ESXi host is set to the same value as the UnityVSA Ethernet ports.

        If the UnityVSA VM sets an MTU value that is higher than the MTU value set on ESXi, the UnityVSA VM MTU value defaults to the smaller value. In vSphere, select Edit Settings on the Virtual switch to check the MTU value.

        In Unisphere, select the Settings icon, and then select Access > Ethernet. MTU is not displayed by default so you must select the Customize icon, select Columns and then click on MTU.

        The VMware Knowledge Base article, iSCSI and Jumbo Frames configuration on VMware ESXi/ESX (1007654), provides more information.

      NOTICE  

      Do not make any changes to the VM, such as changing the virtual hardware configuration (CPU, memory, NICs, and so on), as this causes UnityVSA to boot in service mode in order to prevent invalid configurations.

    Download the OVA file for a single-SP UnityVSA

    Before you begin

    To download the UnityVSA Professional Edition, you must set up a product support account. If you do not already have an account, go to your product support site to set one up. To download the UnityVSA Community Edition, go to the EMC Community Network website.

    Procedure
    1. Using a web browser, go to your product support or community site.
    2. Select UnityVSA.
    3. Locate the available downloads.
    4. Select the UnityVSA Open Virtualization Appliance (OVA) file.
    5. Save the OVA file to your computer.

    Deploy a single-SP UnityVSA directly to an ESXi host

    Procedure
    1. Access the ESXi server by using its IP address.
    2. Select Virtual Machines > Create / Register VM to launch the wizard. Using the wizard, complete the following steps.
    3. Select Deploy a virtual machine from an OVF or OVA file.
    4. Enter a name for the new VM and select the OVA file to deploy.
    5. Verify the OVF template details, including that the OVA image is signed by Dell EMC.
    6. Select a datastore from the list of datastores accessible from the resource you selected in which to create the virtual disks used to store the VM configuration files.
      For optimal performance, if you are not deploying UnityVSA on a VxRail appliance, deploy the UnityVSA VM on a datastore comprised of different physical disks than the datastore that will contain the virtual disks that provide user data storage to UnityVSA. Failure to follow this recommendation can lead to system and I/O performance degradation. If you are deploying UnityVSA on a VxRail appliance, vSAN selects the physical disks.
    7. Select the network mapping, disk provision type, and power on option for the VM.
    8. Enter the system name and configure the management IP (IPv4 or IPv6).
    9. Review the deployment settings and finish the wizard.
    10. Select the UnityVSA VM. Select the Summary tab to view information about the VM.
    11. To determine when the UnityVSA VM is fully up and running, monitor the DNS Name field on the Summary tab. When the DNS Name field displays a system name, the UnityVSA VM is ready.
      Note:  The system name displayed is either the name you specified during deployment or the serial number of the system (format is VIRTXXXXXXXXXX).
    12. If you are running the UnityVSA VM on a dynamic network using DHCP or SLAAC, the management IP address is assigned automatically.
      You can find the assigned IP by logging into the UnityVSA.
    13. If you are not running the UnityVSA VM on a dynamic network using DHCP or SLAAC and you did not configure the management interface when you deployed the OVF template, you must do the following:
      1. Open the vSphere Console.
      2. Log in using the service account username and password service/service
      3. Run the svc_initial_config command to assign an IP address.
      For an IPv4 address, enter:
                                svc_initial_config -4 "<ipv4_address> <ipv4_netmask> <ipv4_gateway>"
                              
      For an IPv6 address, enter:
                                svc_initial_config -6 "<ipv6_address> <ipv6_prefix_length> <ipv6_default_gateway>"
                              
      For full usage, enter:
                                svc_initial_config -h 
      		  
                              
      Note:  Alternatively, you can run the svc_diag command from the vSphere Console and identify the UnityVSA system serial number from the output. Then you can use the Connection Utility to discover a list of systems, find the UnityVSA serial number in the list, and assign an IP address.
    14. Enter the UnityVSA management IP address in your browser to open Unisphere.

    Deploy a single-SP UnityVSA through a vCenter server

    Procedure
    1. Access vCenter using this URL: https://<vCenter_address>/ui.
    2. Select the host, select Actions and select Deploy OVF template to launch the Deploy OVF Template wizard. Using the wizard, complete the following steps.
    3. To select the source from which to deploy, select Local File and then click the Choose Files.
    4. Select a folder or datacenter location for the new VM.
    5. Optionally, change the compute resource to a different host. By default, the host on which you invoked the wizard is selected.
    6. Verify the OVF template details, including that the OVA image is signed by Dell EMC.
    7. Select a datastore from the list of datastores accessible from the resource you selected in which to create the virtual disks used to store the VM configuration files.
      For optimal performance, if you are not deploying UnityVSA on a VxRail appliance, deploy the UnityVSA VM on a datastore comprised of different physical disks than the datastore that will contain the virtual disks that provide user data storage to UnityVSA. Failure to follow this recommendation can lead to system and I/O performance degradation. If you are deploying UnityVSA on a VxRail appliance, vSAN selects the physical disks.
    8. Select a disk format for provisioning the VM's virtual disks.
      Note:  For better performance, it is recommended that you select Thick Provision Eager Zeroed.
    9. Select a VM storage policy, if applicable.
    10. Configure the networks the deployed VM should use, making sure that:
      • The management network is on a network accessible by the workstation used to access Unisphere.
      • The data networks are on networks accessible by the host that will attach to the UnityVSA.
      Note:   If you are deploying the UnityVSA on a VxRail appliance, it is recommended that you deploy the UnityVSA on the same port group used by the client VMs that reside on the VxRail appliance.
    11. Customize the settings for the UnityVSA VM, including the system name and the network:
      1. Enter a user friendly name for the UnityVSA. Leave this field blank to use the default name: an automatically generated serial number for UnityVSA.
      2. If you want to use static IP addresses, enter the IPv4 and IPv6 management settings.
      3. If you want to use dynamic IP addresses, leave these fields blank for automatic configuration using DHCP.
      4. If you do not have a dynamic network and you do not specify a static IP address, you must specify the IP address after the OVF template is deployed.
    12. Confirm the settings, and then click Finish to deploy the OVF template.
    13. Select the UnityVSA VM. Select the Summary tab to view information about the VM. If it is not already powered on, select Power On to start the VM.
    14. To determine when the UnityVSA VM is fully up and running log in to UnityVSA to check.
      Note:  The system name displayed is either the name you specified during deployment or the serial number of the system (format is VIRTXXXXXXXXXX).
    15. If you are not running the UnityVSA VM on a dynamic network using DHCP or SLAAC and you did not configure the management interface when you deployed the OVF template, you must open the vSphere Console and login using the service account service/service and run the svc_initial_config command to assign an IP address.
      For an IPv4 address, enter:
                                svc_initial_config -4 "<ipv4_address> <ipv4_netmask> <ipv4_gateway>"
                              
      For an IPv6 address, enter:
                                svc_initial_config -6 "<ipv6_address> <ipv6_prefix_length> <ipv6_default_gateway>"
                              
      For full usage, enter:
                                svc_initial_config -h 
      		  
                              
      Note:  Alternatively, you can run the svc_diag command from the vSphere Console and, from the output, identify the UnityVSA system serial number. Then use the EMC Connection Utility to discover a list of systems, find the UnityVSA serial number in the list, and assign an IP address.
    16. Enter the UnityVSA management IP address in your browser to open Unisphere.

    Add virtual disks to a single-SP UnityVSA deployment

    When you create the UnityVSA VM, three virtual disks (vmdks) are automatically created for the VM's system data. These are the virtual disks identified as 1-3. Do not modify or delete these disks.

    You must add at least one virtual disk for user data. You can add more virtual disks, up to the system limit (16), when additional storage for user data is needed. The minimum virtual disk size is 10 GB. A disk appears as faulted if it is smaller than 10 GB and larger than the storage size allowed by the UnityVSA edition and version. To view your system's limits, in Unisphere select the Settings icon, and then select Software and Licenses > System Limits

    The following considerations apply to virtual disks in a single-SP UnityVSA deployment:

    • For optimal performance, it is recommended that you create the virtual disks used to provide user data on a different datastore than the one where UnityVSA is deployed. Failure to follow this recommendation can lead to system and I/O performance degradation.
    • You can only connect 12 virtual disks for user data to the first VMware paravirtual SCSI controller provided with the UnityVSA. If you add a 13th virtual disk, select the second controller. Make sure this controller is of type VMware paravirtual. If the SCSI controller is a different type, UnityVSA can have boot problems and can fail to recognize the new virtual disks attached to it.
    • Allow up to 60 seconds for UnityVSA to recognize and display the newly attached virtual disks.
    • Using vSphere to modify the physical configuration of a UnityVSA VM (such as adding or removing network interfaces or modifying the VM's cache size) is not supported, except for adding virtual disks to store user data.
    Procedure
    1. In vSphere, right-click on the UnityVSA SPA VM, and select Edit > Settings.
    2. On the Virtual Hardware tab, select Add New Device > Hard Disk.
    3. Enter the size and provisioning method of the disk you want to add.
    4. Finish stepping through the wizard, and select Finish.
    After you finish
    Note:   Resizing a virtual disk through VMware is not supported in UnityVSA. However, if the virtual disk is not part of a storage pool, you can remove it from UnityVSA and add a new one of the preferred size. Resizing virtual disks that are already part of a storage pool can result in a failed, unrecoverable pool.
