Operating System Installation and Application Setup

This chapter contains the following topics:

Setting Up CVP

Note: Single-Node is not supported for production deployments but can be used for training or feature evaluation.

Pre-installation Checklist

  • Ensure that you have console access to the CVP virtual machine on each appliance, via WOK web access. See Web Access into CVX and CVP Consoles via WOK.
  • Enter the CVP Console.
  • Ensure all configurations are done via console and not via SSH.
Note: This configuration will change the IPs and will drop connectivity if done over SSH.

Setup Steps for Single Node CVP

To set up single node CVP, complete the following steps.

  1. Access the primary CVP VM via WOK.
  2. Refer to the CloudVision Configuration Guide for the Shell-Based Configuration of a Single-Node.

Setup Steps for Multi-node CVP Cluster

Assign to each of the three CVP VMs a role (primary, secondary or tertiary).

  • The roles may be assigned in any way, but the roles must be kept consistent throughout the installation. No two nodes may share the same role.
  • Maintain the installation order starting with primary, then secondary, and finally tertiary.

To assign the roles, complete the following steps.

  1. Print the CloudVision Worksheet. Circle the role of each appliance: one primary (P), one secondary (S), and one tertiary (T).
  2. Access the primary, secondary, and tertiary CVP VMs on the respective appliance via WOK.
  3. Refer to the CloudVision Configuration Guide for the Shell-Based Configuration of Multi-Node.

Log into the CVP Web Interface

After CVP is running on the multi-node appliance cluster, enter the CVP Web Interface of the primary node via its CVP IP/Hostname with default username/password of cvpadmin/cvpadmin to set the password.

For Multi-node clusters, setting the password only has to be done on one node, and is synced to other nodes so subsequently any node can be accessed via its web interface. Refer to the CloudVision Configuration Guide for instructions on using CVP.

Blinking amber Indicates a problem with the PSU.
Not illuminated Power is not connected to the PSU.
Blinking green When the firmware of the PSU is being updated, the PSU handle blinks green.
CAUTION: Do not disconnect the power cord or unplug the PSU when updating the firmware. If the firmware update is interrupted; the PSUs do not function.
Blinking green and turns off When hot-plugging a PSU, the PSU handle blinks green five times at a rate of 4 Hz and turns off. This indicates a PSU mismatch concerning efficiency, feature set, health status, or supported voltage.
CAUTION: If two PSUs are installed, both the PSUs must have the same type of label; for example, Extended Power Performance (EPP) label. Mixing PSUs from previous generations of PowerEdge servers is not supported, even if the PSUs have the same power rating. This results in a PSU mismatch condition or failure to turn the system on.
CAUTION: When correcting a PSU mismatch, replace only the PSU with the blinking indicator. Swapping the PSU to make a matched pair can result in an error condition and unexpected system shutdown. To change from a high output configuration to a low output configuration or vice versa, you must turn off the system.
CAUTION: AC PSUs support both 240 V and 120 V input voltages except for Titanium PSUs, which support only 240 V. When two identical PSUs receive different input voltages, they can output different wattage, and trigger a mismatch.
CAUTION: If two PSUs are used, they must be of the same type and have the same maximum output power.

Tools to Manage and Update Images for the Virtual Machine

A number of tools are available to help manage and update images and insert ISO to the Virtual Machine (VM).

This section contains the following topics:

Upgrade the Host Image

Arista provides an executable that will update all packages in the CVA.

Note: This process re-boots the entire system.

Single Node CloudVision Appliance

To upgrade a single node CVA, perform all the steps listed in Steps to Upgrade the CVA. After the CVA host comes up, and after rebooting the system from the last step of upgrade, allow 20 minutes for the CVP application to be accessible again.

Multi-Node CloudVision Appliance

Perform a rolling upgrade to update the CVA systems in multi-node configuration. Perform all the steps listed in section Steps to Upgrade the CVA from the start to finish on only one of the CVAs at a time. After the upgrade, wait for all the VMs, (CVP and CVX) to be fully up and running (CVP takes 20 minutes to be up from reboot). Verify that the CVP is accessible. After the verification, proceed to upgrade the second CVA host in a similar fashion and then the third CVA.

Note: Process only one CVA upgrade at a time in a multi-node system.

Steps to Upgrade the CVA

  1. Download the upgrade executable (upgradeCva-<version>) from from http://www.arista.com.
     
  2. Run the upgrade executable. 
    ./upgradeCva-<version> --force
    Note:The version can be verified after upgrade using the "version" command. 
    # version
CVA Version: 2.1.3.1

Redeploy CVP VM Tool

 

This tool allows redeployment of the CVP VM in the event:
  • Something goes wrong during deployment.
  • If you want to do a destructive upgrade. Use to delete the virtual CVP disks.
Note: You should backup the CVP data using CVP tool before using this method.

Complete the following steps:

  1. Locate the disks and tool package (cvp-<version>-kvm.tgz) in the CloudVision Portal folder for your version.
    (You can download the package from https://www.arista.com.)
  2. SSH into the CV appliance Host OS.
  3. Backup CVP data using the CVP tool as documented in the CloudVision Configuration Guide under Upgrading CVP in the subsection titled Backup and Restore (recommended). (https://www.arista.com/en/support/product-documentation.)
  4. Copy wget cvp-<version>-kvm.tgz package into the CVA host OS under a new directory.
  5. tar -zxvf cvp-*-kvm.tgz disk1.qcow2
  6. Run it as follows: /cva/scripts/redeployCvpKvmVm.py --disk1 disk1.qcow2 [--mem <mem gb>] [--cpu <vcpu count>] [--data-size </data disk size>] [--cdrom <cvp config iso>]
    usage: redeployCvpKvmVm.py [-h] [-c CDROM] --disk1 DISK1 [--mem MEM] [--cpu CPU] [--data-size DATA_SIZE]
    This script helps redeploy a CVP VM. After the VM is deployed, follow Setup Steps for Single Node CVP, or Setup Steps for Multi-node CVP Cluster by logging into the CVP VM console shell as cvpadmin.
    Note: Use caution before using redeployCvpKvmVm.py as this will stop and restart your VM and delete all your VM disks, i.e. data. BACKUP your VM data prior to running this, as suggested in step 3.

Disk Expansion and Conversion For CloudVision VM

 

CloudVision VMs virtual disks are shipped in qcow2 format with by default, a data disk size of 1TB. For better scale and performance, it is recommended that the virtual disks be converted to raw format, and data disk expanded to a size more appropriate to the expected cale. At max scale supported today we recommend a 4.5TB /data disk.

The tool can be run as /cva/scripts/cvaDiskUtil.py. It supports three commands:
  • status - Display current CloudVision VMs virtual disk information and information about the partition where the VM is placed.

    Example

    /cva/scripts/cvaDiskUtil.py[status]

  • makeraw - Convert qcow2 format virtual disks in CloudVision VM to raw format.

    Example

    /cva/scripts/cvaDiskUtil.py makeraw [--quiet]

  • expand - Increase size of /data virtual disk in CloudVision VM.

    /cva/scripts/cvaDiskUtil.py expand [--disk-size DISK_SIZE] DISK_SIZE can be in KB, MB, GB or TB

Note: makeraw and expand commands will stop and start cvp VM.
