Upgrade the BFC

To upgrade the Backbone Fabric Controller you first download the BFC installer file, then run the upgrade program.

Get the BFC installer from download.3tera.net

1. On a server that has internet access and you are logged into as the user whose public SSH key you provided to CA for download access, run one of the following commands to copy over the BFC installer. It is preferred to use the rsync command to perform the copy operation as it can checksum the data too. If you’re on a machine with only SSH then you can use the scp command provided but make sure to compare the MD5 hashes provided in the packing.slip file post download to verify that the download completed successfully.
   1. (PREFERRED METHOD)
      • cd to the directory where you want to download the BFC installer media.
      • "rsync -avcLP --delete -e 'ssh -i full_path_to_key' applogic@download.3tera.net:~/BFC/current ."
   2. (OPTIONAL METHOD)
      • cd to the directory where you want to download the BFC installer media.
      • "scp -r -i full_path_to_key applogic@download.3tera.net:~/BFC/current ."
      • cd into the ‘current’ directory created in the above command.
      • "md5sum -c packing.slip" which will verify each file automatically and show an OK status for each file.

Upgrade the BFC

1. Log into the BFC control node as root using SSH.

   Note: Before you upgrade the BFC, make sure that SSH password authentication is disabled on the BFC control node. To restrict SSH to key-based logins, do the following:

   • Add a key to /root/.ssh/authorized_keys and verify that you can login using the key alone (no password prompted for or supplied).
   • Set the 'ChallengeResponseAuthentication' and 'PasswordAuthentication' parameter values to 'no' in '/etc/ssh/sshd_config'.
   • Execute 'service sshd reload' to load the modified parameters.
2. Copy the BFC installer ISO’s sync’d above to /tmp/BFC.

   Note: Do not copy the files to /opt/bfc as that is the default directory for the installation of the BFC and is removed and recreated during the installation process).

3. Mount the BFC ISO.

   mkdir -p /mnt/cdrom
   mount -r -o loop /<path to bfcinstall.iso> /mnt/cdrom 
   

   (for example, mount -r -o loop /tmp/BFC/bfcinstall.iso /mnt/cdrom)

4. Run the BFC installer. Type the following command then press Enter:

   /mnt/cdrom/fcinstall.sh -x /<path to bfcext.iso> -u
   

   The "BFC upgrade was successful" message appears when the upgrade completes.
