BFC Known Issues

We have identified the following known problems with the Backbone Fabric Controller (BFC) in this release:

1. If you are running a BFC database replica on an NFS hard mounted file system (NFS hard mounts are the default; do not use the optional soft mount functionality), and that NFS-mounted file system fails, the BFC will hang. This issue is a characteristic of NFS itself, and not something the BFC has direct control over. If you end-up in this state and you are unable to restore the NFS file system, you can remove the BFC dependence on that replica to restore normal operation using the following steps:
   1. Log in to the BFC system as root.
   2. Change to the bfcadmin user by typing the following command:

        su - bfcadmin
      

   3. Run <BFC install location>/bin/stop_replication (by default, /opt/bfc/bin/stop_replication)

   Important! After breaking this dependence, your system will be running without replica, so go back into the UI and establish another replica at the same or a different location.

2. Do not use the /home/bfcadmin folder for your replica database, or as your download directory for versions, hotfixes, and updates. If you uninstall the BFC, this folder is removed, resulting in the loss of your replica database and other site-owned data.
3. Defect SCR 6990 - Cannot unset the default VLAN for a grid via the BFC API
4. SCR 6027 - The grid start from BFC UI fails after it is shutdown using “3t grid shutdown” command

   Please do not use the “3t grid shutdown” command on a grid.

5. SCR 6424 -BMI Install prompts for Driver Disk on HP DL360g4p

   If you get this message, simply hit the “Esc” key to continue the install.

6. SCR 7312 - Unattended install fails with password !"$%&/()=?'

   If you are performing an unattended install with this version of the product, your password cannot contain an equals sign (=).

7. SCR 7376 - STP check is skipped during network detection if server’s public port is configured as trunk

   This bug could occasionally allow servers into grids that should be blocked. If the ports are properly configured, this problem will not be encountered.

8. SCR 7401 - BFC throws "System_limit" error when total no. of characters in the "Edit Grid Parameters" textbox exceeds 256 characters

   If you need to use more than 256 characters, simply break those parameters into more than one update of the grid.

9. SCR 7724 - system with 1000 MACs set to AutoDiscovery (blacklist) mode brings BFC down

   If you need to set these many MACs to AutoDiscovery (blacklist) mode, it would be best to use Manual Configuration (whitelist) mode with 3.5.

10. SCR 7984 - Issues with updating of app IP and controller IP after hitting Reset button

    Due to this bug you cannot directly swap the controller and application IPs with each other in one step. If you must do this, first set them to some other values, then you may set them again to the intended values.

11. SCR 8005 - API: Issues while adding VLAN to the existing untagged grid via API

    If you attempt to add a tagged network to an untagged grid via the API, the call will succeed, instead of returning 400 Bad Request.

12. SCR 8231: Download error message not clear when selecting to download an already downloaded version

    This is not really an error, just a confusing message.

13. SCR 7815: BFC API allows a vlan to be added to a grid multiple times

    You can use the API to add the same range multiple times, but you can not use the UI to remove the duplicate ranges. Leaving the duplicate ranges in place does not cause problems.

14. SCR 8452: Some Dell machines will not boot into a grid if the Virtual Media option is enabled in the DRAC

    On some Dell hardware you can enable a DRAC Virtual Media BIOS option. This feature allows you to boot from a virtual media device over the network. However, the CA AppLogic kernel may identify the virtual media device as a SCSI device and confuse the boot device name (what was sda becomes sdb).

    To avoid this problem, disable the DRAC Virtual Media option in the DRAC BIOS on your Dell hardware.

15. SCR 8400: BFC service crashes when adding a very large MAC address list to the discovery white list or black list

    When you add or remove addresses to the list of MAC addresses in the BFC, limit the maximum number to 500. The MACs list is used in Discovery Mode to include servers (when set to Manual Configuration) or exclude servers (when set to Auto Discovery mode).

    You can work with the list of MACs on the Administration page of the BFC on the Discovery tab. You can edit the list of servers, or can import a file with a list of servers. You can also set the MAC address list using the BFC API.
