QRadar: How to verify IMM or XCC network speed before you begin and update or installation

How To


Summary

How to verify if Integrated Management Modules (IMM), or XClarity Controllers (XCC), network speeds create high probability of success for remote mounting?

Objective

Important: QRadar ISO software installations are not intended over Integrated Management Modules (IMM) or XClarity Controllers (XCC) and are not supported. Remote software installations of QRadar over IMM, or XCC, are not validated by development or quality teams.
Known errors related to software installations over IMM, or XCC:
  • Administrators with network speeds under 1000 Mbps report installation errors over remote mount.
  • Network infrastructure, such as IPS devices or firewalls can drop connections, leading to installation errors.

Steps

WARNING: Remote mount of software installation files, ISO, can corrupt the environment. This corruption can result in reinstalling locally in the Data Center. Administrators with network speeds under 1000 Mbps report installation errors with remote mounting.

How to check network speeds by using IMM, or XCC, status tools?

  1. Log in to IMM web UI.
  2. Go to Server Management > Remote Control.
  3. Select Use the Java Client.
  4. Select Start remote control in multi-user mode.
  5. Once IMM opens, select Tools > Stats.
  6. Verify your bandwidth is above 1000 Mbps. If not above 1000 Mbps, use the USB method and not remote mounting.

How to check network speeds using SSH?

  1. Using the username and password for the IMM web UI, SSH into the IMM with verbose logging turned on (-v). Verbose enables some connection stats when you exit as well.
  2. Review the network configuration: 
    ifconfig eth0
    Note: Might take a minute or two.
  3. Verify the following variables:
    -r greater than or equal to 1000
    -d = full
    -m = 1500
    Note: If they report as auto, then they could be getting much less from the router. If you see other values, update the router to the correct settings.
  4. Exit connection: 
    exit
  5. Record bandwidth stats: 
    Bytes per second: sent {N1}, received {N2}
