Client Connectivity

Table of Contents

Overview

Before running an operation in the CommCell, you may want to check the connectivity between the client and the CommServe. You can check the connectivity in the following ways:

  • From CommCell Console
  • From Command Line
  • Run CommCell Readiness Report

The following sections describe how to perform each of these operations.

Checking Connectivity from the CommCell Console

You can check whether or not a client is accessible in the CommCell using the Check Readiness option in the CommCell Console.

When selected, this option will display a message indicating whether or not the client is accessible.

Use the following steps to check client connectivity from the CommCell Console:

  1. From the CommCell Browser, right-click the client computer whose connectivity you want to check and then click All Tasks.
  2. Click Check Readiness.
  3. A message is displayed indicating whether or not the client is accessible in the CommCell.
  4. Click the Show Details button.
  5. Click Close.

Checking Connectivity from the Command Line

The CVPing mode of the CVNetworkTestTool Utility mode lets you troubleshoot and test network connectivity between two clients.

CVPing performs a name lookup, then pings the IP address of the destination computer to check its network connectivity.

Follow these steps:

  1. Change to the software installation base directory for the instance to test:

    cd software_installation_path/Base

  2. Test the connectivity:
  3. CvNetworkTestTool -Utility –cvping –log location -HostName name [-UseIPv4 | -UseIPv6 | -UseIPAny] [-Port port_number]

    where:

    • Utility means to run in utility mode.
    • cvping tells the command to verify connectivity using CVPing mode.
    • log is the location of the log file.
    • HostName is the host name of the destination computer.
    • (Optional) UseIPv4 | UseIPv6 | UseIPAny, specifies the protocol to use for network communication. If not supplied, IPv4 protocol is used.
    • (Optional) Port port_number is the port number of the destination computer to be used for testing connectivity. If not supplied, port 8400 is used.

    For example:

    CVNetworkTestTool -Utility -CVPing –log C:\CVPing.log -HostName cvhost1 -UseIPv4 -Port 8400

  4. The command returns the result of network connectivity testing.

CommCell Readiness Report

The CommCell Readiness Report provides you with vital information such as connectivity and readiness of the Client, MediaAgent, and CommServe. It is useful to run this report before performing a backup or a recovery operation. Follow the steps given below to generate the report:
  1. On the CommCell Console menu bar, select the Reports tab.
  2. Click Readiness.

    The Report Selection dialog box appears.

  3. If necessary, select Reports | CommServe | CommCell Readiness in the left pane.
  4. Select the Computers tab, and then click Modify below the Computers list.
  5. In the dialog box that appears, clear Include All Client Computers and All Client Groups.
  6. Select the appropriate client from the Exclude list, and then click Include >.
  7. Click OK.
  8. Select the MediaAgent tab, and then clear Include All MediaAgents.
  9. Select the appropriate MediaAgent from the Exclude list, and then click Include >.
  10. Click Run.

    The report appears in your default Web browser.

Refer to CommCell Readiness Report for more information.

Troubleshooting Connectivity Errors

Make sure that the computer is accessible in the network. You can do this using the CVPing command or other such network utilities.

If the client computer is not accessible in the network, ensure that the NetApp services are running on the client. If necessary, you can restart the services on the client. See Services - Advanced for step-by-step instructions.

Check Readiness Errors

Problem

Readiness check fails intermittently.

This can occur if the firmware of the network adapters is a mismatch and not updated.

Solution

Update the firmware to match with all network adapters. This will ensure proper connectivity through the Network adapters and in most cases the check readiness will succeed.
