Cisco UCS C-Series Servers
Statement of Volatility


The Cisco UCS C-Series rack-mount servers have multiple serial, electrically erasable, and programmable nonvolatile memory components (EEPROM and flash memory) that are used to store manufacturing hardware identification and hardware configuration information. The majority of serial EEPROMs and flash memories are not written by users and contain no customer information. Procedures for clearing the few flash devices that can retain customer data are included in this document.

This document applies to the following servers:

Cisco UCS C22 M3 and C24 M3

Cisco UCS C220 M3 and C240 M3

Cisco UCS C420 M3

Cisco UCS C260 M2

Cisco UCS 460 M2

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:

Storcli64 /cx delete events
Storcli64 /cx delete securitykey
Storcli64 /cx delete termlog
Storcli64 /cx flush
Storcli64 /cx/vall delete preservedcache force
Storcli64 /cx del Nytrocache
Storcli64 /cx/vx delete BBMT
Storcli64 /cx set factory defaults
