Installing the Cisco Nexus 1000V Software Using ISO or OVA Files

This chapter contains the following sections:

Installing the VSM Software

Installing the Software from the ISO Image

Before You Begin
  • The ISO image is located at zip_file_location/Nexus1000v.4.2.1.SV2.1.1a/VSM/Install/ nexus-1000v.4.2.1.SV2.1.1a.iso
  • You have already read the Prerequisites for Installing the Cisco Nexus 1000V.
  • You have already manually provisioned the VM to be used for the VSM. For more information, see the vSphere Virtual Machine Administration Guide.
  • The VSM VM requires the following and this procedure includes steps for updating these properties:
    • Minimum of 2 GB of RAM reserved and allocated.
    • Minimum CPU speed of 1500 MHz.
  • Do not create more than one virtual CPU. The Cisco Nexus 1000V supports only one virtual CPU.
Procedure
    Step 1   Using your VMware documentation, attach the VSM ISO image to the virtual CD-ROM and copy the software to a virtual machine (VM).
    Step 2   Make sure that the VSM VM is powered off.
    Step 3   In the vSphere client Virtual Machine Properties window Hardware tab, choose Memory.
    Step 4   In the Memory Size field, choose 2 GB.
    Step 5   In the Resources tab, choose Memory.

    The Resource Allocation settings display in the right-hand pane.

    Step 6   In the Reservation field, choose 2048 MB.
    Step 7   In the Resources tab, choose CPU.

    The Resource Allocation settings display in the right-hand pane.

    Step 8   In the Reservation field, choose 1500 MHz.
    Step 9   Click OK.

    The VSM VM memory and CPU speed settings are saved in VMware vSphere Client.

    Step 10   Right-click the VSM and choose Open Console.
    Step 11   Choose Install Nexus1000V and bring up the new image entry and press Enter.
    Figure 1. Install Nexus1000V and Bring Up the New Image Window

         ---- Basic System Configuration Dialog ----

This setup utility will guide you through the basic configuration of
the system. Setup configures only enough connectivity for management
of the system.

*Note: setup is mainly used for configuring the system initially,
when no configuration is present. So setup always assumes system
defaults and not the current system configuration values.

Press Enter at anytime to skip a dialog. Use ctrl-c at anytime
to skip the remaining dialogs.

Would you like to enter the basic configuration dialog (yes/no): 


This example shows the HA role as secondary. 
Enter HA role[standalone/primary/secondary]: secondary


  Setting HA role to secondary will cause a system reboot. Are you sure (yes/no) ? :
    Step 15   Do one of the following:
    • If you are setting up the primary/active VSM, go to Step 18.
    • If you are setting up the secondary/standby VSM, then continue with the next step.
    Step 16   If you have set up the VSM virtual machine (VM) to boot from the CD-ROM, and are installing the secondary VSM from the ISO image attached to your CD-ROM, remove the virtual CD-ROM now so that the VSM does not boot from the CD.

    This step is necessary if you have set up the VSM VM to boot from the CD-ROM before the hard drive.

    Step 17   If you are setting up the secondary/standby VSM, when prompted to reboot the VSM, answer yes.

    The secondary VSM VM is rebooted and brought up in standby mode.

    The password on the secondary VSM is synchronized with the password on the active/primary VSM.

    Any configuration made on the active/primary VSM is now automatically synchronized with the standby.

    This example show the system rebooting when the HA role is set to secondary.
