Creation of Broadcom RAID-controller logs with BCMget

In this article, we explain how to create support logs for your Broadcom MegaRAID-controllers. Broadcom provides the BCMget-script for this purpose, which is available in different versions depending on the controller type.

BCMget-script

The BCMget-script serves for the automatic recording of all relevant diagnostic information of your Broadcom RAID-controller (configuration, log files, status information,...).

The script variant, that must be downloaded, is dependent on the used controller model:

• For 96xx-controller:

  BCMget-script for 96xx-controller

• For 95xx-controller as well as Legacy 93xx/94xx-controller:

  BCMget-script for 95xx- and older 93xx/94xx-controller

Detailed instructions for executing the script can be found in the following paragraphs:

• Linux: Creating logs under Linux
• Windows: Creating logs under Windows

Linux

Preparations

To create the logs, you need the appropriate BCMget-script variant for your controller. Make sure that you have completely unzipped the downloaded archive.

The log creation can be made in two different ways:

• via remote access (file transmission via network),
• locally on the system (for example a directly connected console and USB-stick).

Remote access

Requirements

The following additions are required for implementation:

• FTP- or SFTP-access
• SSH-access (for executing the script).

Used tools in this example:

• Ubuntu
• PuTTY
• WinSCP

Creation via remote access

• 
  Step 1: Start WinSCP, enter the IP address of the Linux server and log in with the user root..
• 
  Step 2: Create a new folder in the /tmp directory (for example /tmp/BCMGet) and upload the whole content of the unzipped BCMget archive to this folder.
• 
  Step 3: Log in to the Linux server as the root user via SSH (for example using PuTTY).
• 
  Step 4: Switch to the script directory, for example with cd /tmp/BCMGet.
• 
  Step 5: Make the script executable, for example with: chmod +x bcmget_linux_xxxxxx.sh.
• 
  Step 6: Execute the script, for example with: ./bcmget_linux_xxxxxx.sh. Wait until data collection is complete.
• 
  Step 7: Download the archive created by the script (for example bcm_logs_hostname.tgz) with WinSCP from the /tmp/BCMGet directory on your client.
• 
  Step 8: Send the archive together with a detailed description of the error and the serial number of the server to support@thomas-krenn.com.

Local

Prerequisites

For local creation, you will need:

• access to the system console (e.g., directly on the device or via iKVM),
• a USB stick for transferring the BCMget script and for copying the log files later

Local creation on the system

• 
  Step 1: Connect a USB-stick with your client.
• 
  Step 2: Copy the unzipped content of the BCMget-archive on the USB-stick.
• 
  Step 3: Insert the USB stick into the server.
• 
  Step 4: Open the console of the server (for example locally or via iKVM) and log in as root user.
• 
  Step 5: Identify the USB stick device withlsblk (for example. /dev/sdc1).
• 
  Step 6: Create a mount point under /mnt, for example with: mkdir -p /mnt/usb.
• 
  Step 7: Connect the USB stick, for example with: mount /dev/sdc1 /mnt/usb and then change to the directory of the USB stick: cd /mnt/usb.
• 
  Step 8: Create the /tmp/BCMGet directory and copy all script files, for example: mkdir -p /tmp/BCMGet && cp -r * /tmp/BCMGet && cd /tmp/BCMGet.
• 
  Step 9: Make the script executable, for example with: chmod +x bcmget_linux_xxxxxx.sh.
• 
  Step 10: Execute the script, for example with: ./bcmget_linux_xxxxxx.sh. Wait until the log archive has been created.
• 
  Step 11: If necessary, copy the created archive to the USB stick, then unmount the USB stick (for example with umount /mnt/usb) and remove it from the server. Connect the USB-stick again with your client.
• 
  Step 12: Send the created archive together with a detailed error description and the serial number of the server to support@thomas-krenn.com.

Windows

Preparation

To create the logs in Windows, you need the appropriate BCMget-version for your Broadcom RAID controller.

Execution

• 
  Step 1: Connect to the Windows server—either locally or via Remote Desktop Protocol (RDP).
• 
  Step 2: Download the required BCMget package to the server or copy it from your client to the server.
• 
  Step 3: Unzip the downloaded archive completely into a directory of your choice.
• 
  Step 4: Open the unzipped directory and double-click the bcmget.batfile to start it.
• 
  Step 5: The script will now automatically collect all relevant data from the RAID controller. This process may take several minutes.
• 
  Step 6: Once data collection is complete, you can terminate the script by pressing any key, as indicated in the window.
• 
  Step 7: The log archive created is stored in the BCMget directory. Copy this archive back to your client.
• 
  Step 8: Send the created archive together with a detailed error description and the serial number of the server to support@thomas-krenn.com.
