Preparation

Back Panel Ethernet Connections

On the back panel of the CloudVision appliance, locate the Ethernet Inte grated 10/100/1000 Mbps NIC connectors.

Figure 3: Back Panel

7

Figure 4: Management Subnet

iDRAC is an Intelligent Platform Management Interface (IPMI) that provides a GUI-based out-of-band
interface for monitoring the hardware appliance. iDRAC uses NIC1 for its network connectivity using a
unique MAC

address.

Note: iDRAC may also be refereed to as Lifecycle Controller.

DNS Entries

In order to manage your CloudVision cluster, it is often easier to connect to them by hostname as opposed to IP
address. Fully qualified domain names (FQDNs) should be allocated to:

• Each of the CloudVision Appliance host machines.

• Each of the CloudVision Appliance iDRAC interfaces.

• Each of the CloudVision Portal (CVP) nodes.

• Each of the CloudVision Server (CVX) nodes.
Contact your DNS zone administrator for assistance.

CloudVision Appliance IP Configuration

The CloudVision Appliance Host and iDRAC IP addresses can be allocated in either of two ways:

Option 1: Using an available DHCP server

• DHCP Based IP Address Setup.

• Web Access into Host via WOK.

Option 2: Manual configuration (Requires terminal connected to VGA port)

8

DCA-100-CV Quick Start Guide

• Manual IP Address Setup.

• Web Access into Host via WOK.

DHCP Based IP Address Setup

Note:

The iDRAC interface shares the NIC1 physical interface but has a different MAC address. You will need
to take note of this MAC address to map the DHCP address for the iDRAC interface.

Manual IP Address Setup

Note:

Direct IP Address Setup requires a terminal connected to the VGA port of the appliance. This section can
be skipped if the Host and iDRAC IP addresses have been configured with a DHCP server.

See the Back Panel Features and Indicators for complete back panel descriptions.

IPMI IP Address

Preparation

The IPMI IP address can be manually configured via the host's bash shell using the racadm tool. The racadm
commands below are sequence dependent and must be entered in the following order.

1. Using the attached terminal and keyboard, log in as user using “root” with the default password of “arista”.

You should now be logged into the appliance.

2. Disable all IPMI related DHCP configurations.

racadm set iDRAC.IPv4.DHCPEnable 0
racadm set iDRAC.IPv4.DNSFromDHCP 0
racadm set iDRAC.NIC.DNSDomainFromDHCP 0

3. Configure the IP network settings for the IPMI interface.

racadm set iDRAC.NIC.Enable 1
racadm set iDRAC.IPv4.Address <iDRAC-IP>
racadm set iDRAC.IPv4.Netmask <iDRAC-MASK>
racadm set iDRAC.IPv4.Gateway <iDRAC-GW>

4. Configure the DNS settings for the IPMI interface.

racadm set iDRAC.IPv4.DNS1 <iDRAC-DNS1>
racadm set iDRAC.IPv4.DNS2 <iDRAC-DNS2>
racadm set iDRAC.NIC.DNSRacName <iDRAC-NAME>
racadm set iDRAC.NIC.DNSDomainName <iDRAC-DOMAIN.NAME>

5. Verify the configuration by running:

racadm getSysInfo

Host IP Address

The host IP address can be manually configured via the host's bash shell. In order for the settings to be persistent,
the following configuration must be done.

Setting Up CV Applications

Setting Up CVP

Note: Single-Node is not recommended for production deployments.

Pre-installation checklist

• Ensure that you have console access to the CVP virtual machine on each appliance, via WOK web access.

• 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

1. Access primary CVP VM via WOK. See Web Access into CVX and CVP Consoles via WOK.

2. Refer to the CloudVision Configuration Guide for 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.

1. Access the primary, secondary and tertiary CVP VMs on the respective appliance via WOK. See Web Access

into CVX and CVP Consoles via WOK.

2. Refer to the CloudVision Configuration Guide for 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.

17

For Multi-node clusters, setting the password only has to be done on one node, and will be 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.

Tools to Manage and Update Images

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

Topics:

• Upgrade the CVP Image

• Redeploy CVP VM Tool

• Redeploy the CVX VM Tool

• Upgrade the Host Image

• Steps to Upgrade the CVA

Upgrade the CVP Image

The easiest way to upgrade the CVP Image is perform a CVP Fast Upgrade. This upgrade option does not require
that the VMs be redeployed, and does not result in loss of the logs.

Note: Fast upgrades are supported only when upgrading from version 2016.1.1 (or later) of the CVP
application. You cannot use fast upgrades if you are using a version of CVP prior to 2016.1.1.

To use the CVP fast upgrade option, complete the procedure in the “Fast Upgrades” section of the Backup &
Restore, Upgrades, DNS / NTP Server Migration chapter in the CVP Configuration Guide.

If it is not possible for you to use the CVP fast upgrade option, use the procedure in Redeploy CVP VM Tool in
this section.

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. Used to delete the virtual CVP disks.

29

Note: You should backup the CVP data using CVP tool before using this method.

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 CloudV ision Configuration Guide under Upgrading
CVP in the subsection titled Backup and Restore (recommended).

4.

Copy wget cvp-<version>-kvm.tgz package into the CVA host OS under a new directory.

5.

tar -zxvf cvp-*-kvm.tgz

6.

./redeployCvpKvmVm.py -n cvp --disk1 cvp-disk1.qcow2 --disk2
cvp-disk2.qcow2

#redeployCvpKvmVm.py -h
usage: redeployCvpKvmVm.py [-h] [-n NAME] [-c CDROM] --disk1 DISK1 --disk2
DISK2

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.
This will delete all your VM disks i.e. data. B A CKUP your VM data prior to running this, as suggested
in step 3.

Redeploy the CVX VM Tool

This tool enables you to redeploy CVX VMs. You typically redeploy CVX VMs if:

• Something goes wrong during deployment.

• You need to perform a destructive upgrade, which deletes the virtual CVX disks.

Note: Make sure that you complete the backup of CVX data before you use the redeployCvxKvmVm.py
command. This command stops and restarts the VM, which deletes all of the VM disk data. The step used
to backup VM data is Step 4 of the procedure.

1. Go to https://www.arista.com.

2. Locate and download:

•

The CVX disk and the Aboot .iso for the version of CVX you are using.

•

The tool package (arista-cv-<version>-mfg.tgz), which is in the CloudVision Portal folder for
your version.

3. SSH into the CV appliance Host OS.

4. Backup CVX running configuration.

5. Do one of the following:

• Copy the packages, disks, and the .iso archives you downloaded in step 2.

•

Run wget cvp-<version>-kvm.tgz to copy the package into the CVA host OS under a new
directory.

30

DCA-100-CV Quick Start Guide

6.

Extract the kvm.tgz to get the redeployCvxKvmVm.py script (tar -zxvf
cvp-<version>-kvm.tgz).

7.

Copy the downloaded CVX disk and the Aboot disk to /data/cvx/ on the CVA host OS.

8.

Run /redeployCvxKvmVm.py --name cvx --cvxDisk EOS.qcow2 --abootDisk

Aboot-veos-serial.iso.

-bash-4.3$ ./redeployCvxKvmVm.py -h
usage: redeployCvxKvmVm.py [-h] [-n NAME] --cvxDisk CVXDISK --abootDisk
ABOOTDISK
optional arguments:

-h, --help show this help message and exit

-n NAME, --name NAME Name of the CVX VM

--cvxDisk CVXDISK Path to the Cvx/Eos disk

--abootDisk ABOOTDISK Path to the Aboot disk

This script is used to redeploy the CVX Vm on the CloudVision Appliance. It takes in the arguments of the
CVX Disk images and the Aboot disk images if both are not found locally. The CVX/EOS disks and the
Aboot images are available from https://www.arista.com.

Upgrade the Host Image

Arista provides an ISO with all updated packages and a tool to mount the images ISO and upgrade the system.
Make sure you use the correct upgrade procedure based on your current CV Appliance configuration.
The two basic upgrade procedures are:

• Single-node configurations.

• Multi-node configurations.

Single-node configurations

Use the following procedure to upgrade a single-node CV Appliance configuration.

Note: Allow 20 minutes for the CVP application to be accessible again after the CV Appliance host
comes up. The CV Appliance host will come up after the system reboots (running the upgrade script,
which is done near the end of the procedure, automatically reboots the system).

Complete the following steps to upgrade single-node CV Appliance configurations.

1. Go to https://www.arista.com.

2.

Download the mfg tgz tools (arista-cv-<version>-mfg.tgz).

3.

Extract tar -xvf arista-cv-<version>-mfg.tgz. This ensures you have the new version of
upgradeCva.py.

4. Download the update ISO.

5. Run the upgrade CV appliance tool.

./upgradeCva.py -i <Arista Cva Update Iso>
$ ./upgradeCva.py -h
usage: upgradeCva.py [-h] [-i ISO] [--fixNw] [-vm] [-f FORCE]
Upgrade CVA
optional arguments:

-h, --help show this help message and exit

-i ISO, --iso ISO Path to ISO

fixNw Fixes CVA network config to what is expected

Does not touch devicebr config.

-vm,--vm Used for CVA VM emulation - NOT for HW CVA

-f, --force Do what I say. Used for bypassing yes/no
question for reboot.

6.

Use the # version command to verify that the upgrade was successful.

Multi-node configurations

A rolling upgrade should be done when upgrading multi-node CV Appliance configurations. The steps you use
are exactly the same as the steps used for single-node configurations, except that you must repeat the procedure
for each node.

The basic steps involved in performing the rolling upgrade are:

• Login to one of the CV Appliance hosts.

• Complete the upgrade using the steps in the procedure. (Make sure you follow the rules in the Important!

notice below when performing the upgrade.)

• Wait until all CVX and CVP VMs are up and running before you begin the upgrade on the next host.

Note: Important! To complete the rolling upgrade, you must:

• Upgrade only one CV Appliance host (machine) at a time.

• Wait after each host machine is upgraded, until all CVX VMs and CVP VMs are fully up and
running before you begin the upgrade on the next host in the cluster.
C

VP takes approximately 20 minutes to be fully accessible after the system reboot (running the

pgrade script, which is done near the end of the procedure, automatically reboots the system).

u
Verify that CVP is accessible before you begin to upgrade the next CV Appliance host in your
multi-node cluster

configuration.

Complete the following steps to upgrade multi-node CV Appliance configurations.

1. Go to https://www.arista.com.

2.

Download the mfg tgz tools (arista-cv-<version>-mfg.tgz).

3.

Extract tar -xvf arista-cv-<version>-mfg.tgz. This ensures you have the new version of
upgradeCva.py.

4. Download the update ISO.

5. Run the upgrade CV Appliance tool.

upgradeCva.py -i <Arista Cva Update Iso>
$ ./upgradeCva.py -h
usage: upgradeCva.py [-h] [-i ISO] [--fixNw] [--useLacp] [--reboot] [-f]
[-r]

6. Wait until all CVX VMs and CVP VMs are fully up and running. (CVP takes approximately 20 minutes to
be fully accessible after the system reboot.)

7.

Use the # version command to verify that the upgrade was successful.

8. Repeat steps 2 through 7 on each of the remaining CV Appliance hosts you want to upgrade.

Steps to Upgrade the CVA

1.

Download the upgrade executable (upgradeCva-<version>) from https://www.arista.com. Locate the
upgradeCva.py inside the tgz.

tar -zxvf cvp-<version>-kvm.tgz

2. Run the upgrade executable.

./upgradeCva-<version> --force

Note: The version can be verified after upgrade using the "version" command.

# version
CVA Version: 1.2.0

Host Console Access via IPMI

If you have a problem accessing the host externally, SSH into IPMI and access the host console.

Note: This procedure will reboot the server.

Using an SSH client do the steps below:

1.

SSH into the IPMI and login with the root user and idrac password. You will get a login similar to admin->.
This indicates you are in the idrac SSH console.

2. Execute the following commands:

racadm config -g cfgSerial -o cfgSerialBaudRate 9600
racadm config -g cfgSerial -o cfgSerialCom2RedirEnable 1
racadm config -g cfgSerial -o cfgSerialSshEnable 1
racadm config -g cfgIpmiSol -o cfgIpmiSolEnable 1
racadm config -g cfgIpmiSol -o cfgIpmiSolBaudRate 9600
racadm set BIOS.SerialCommSettings.SerialComm OnConRedirAuto
racadm set BIOS.SerialCommSettings.SerialPortAddress Serial1Com2Serial2Com1
racadm jobqueue create BIOS.Setup.1-1
racadm serveraction powercycle

The IPMI should now be configured to access serial console.

3. From the IPMI SSH interface run the command below to access the serial console:

console com2

4.

T o return to the IPMI interf ace and disconnect from the console the def ault escape sequence is ^\ (CTRL+\) or
simply close the SSH window.

1. Locate the MAC addresses for the CloudVision appliance, see Locate the MAC Addresses for the

CloudVision

The information tag is a slide-out label panel which contains system information such as Service Tag, NIC,
MAC address for your reference.

2. DHCP Server Entries: Using the IDRAC MAC and HOST NIC1 MAC.

Input entries into the DHCP Server on Subnet1 for DHCP assigning above IDRAC IP and HOST IP
addresses to those MACs. (iDRAC uses NIC1 for it’s network connectivity.)

3. DNS Server Entries: Input the Host and CVP Hostname/IP entry into your network DNS Server as shown in

Setup Steps for Single Node CVP or Setup Steps for Multi-node CVP Cluster.

Appliance.

Note: CVP IP will not be DHCP configured, it will be statically configured.
