Statement of Volatility for Cisco UCS Hardware

Clearing the Storage Controller TFM Cache

The Cisco UCS C-Series servers might be configured with an LSI storage controller card that has a TFM module for battery-backed cache via a SuperCap power module (SCPM) or battery backup unit (BBU). The TFM module might cache partial user data to prevent data loss. If the server has this configuration, use the following procedure to clear the TFM cache.

Step 1 If not already installed, download and install the LSI StorCLI utility on the server’s operating system (Linux/Windows/VMWare).

The LSI StorCLI utility and its documentation are available for download from LSI.com.

Step 2 Open a new command/terminal window and change to the directory where StorCLI is installed.

Step 3 Run the following commands in the order shown, where x is the number of the controller:

Note Storcli has a help function. For additional information about the listed commands, issue the
./storcli64 help command.

Clearing the CIMC and BIOS

You can restore the BIOS and CIMC to factory default settings and clear the CIMC logs.

Note The WebUI has a navigation pane that expands and collapses. The navigation pane contains tabs that group server functions, for example, Networking for interface and server networking features.

Depending on how the Web UI is configured, the navigation pane might be collapsed and its tabs hidden. You can expand and collapse the navigation pane by clicking the Toggle Navigation button located at the top left corner of the Web UI banner. For ease of use, you might find it helpful to pin the expanded navigation pane so that it remains expanded.

The following procedures are only a subset of tasks for the Cisco UCS C-Series Integrated Management Controller. The full set of features available through the CIMC WebUI and CIMC CLI are documented in the Cisco UCS C-Series Integrated Management Controller GUI Configuration Guide and Cisco UCS C-Series Integrated Management Controller GUI Configuration Guide.
