Introduction
This document describes how to use the FMC GUI to free up disk space on FMC and FTDs running version 7.7.0 or later.
Prerequisites
Requirements
Cisco recommends that you have knowledge of this topic:
- Graphical User Interface (GUI) of Secure Firewall Management Center version 7.7.0.
Components Used
The information in this document is based on these software and hardware versions:
- Secure Firewall Management Center (FMC) with version 7.7.0.
- Secure Firewall Devices (FTD) with version 7.7.0.
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.
Background Information
Insufficient disk space can lead to reduced performance, hinder system upgrades, and heighten the risk of unintentionally deleting critical files during space recovery efforts.
This new utility allows you to click to safely remove unneeded files such as old backups, content updates, and troubleshooting files.
Troubleshoot
Step 1.
Log in to the FMC and if the alert shows the message about Disk Usage in any device, navigate to Health Monitor dashboard, and select the Health Monitor button at the bottom of the Notifications Tab.
