How to turn off the "Invalid or Missing Entitlement Certificates" message on RHEL

If your RHEL system is not registered with Red Hat Network, you will see the warning message, "Invalid or Missing Entitlement Certificates. This system is missing one or more valid entitlement certificates.", at the top right corner after you log in to the system at run level 5.
Of course, the message will be automatically turned off after you register your system with Red Hat. However if you just want to suppress the message without registering the system, that is possible with a few simple steps. What you need is to disable the rhsm-icon process. Here is the procedure.
  1. Log in to your RHEL system.
  2. Open a terminal, and change the current directory to /etc/xdg/autostart
  3. $ cd /etc/xdg/autostart
    
  4. Rename the rhsm-icon.desktop file.
  5. $ mv rhsm-icon.desktop rhsm-icon.desktop.bak
  6. Log out and log back in to the system
Now you don't see the warning message :)

Setting up JBOD with Fujitsu D2607 RAID Card on PRIMERGY Servers

Fujitsu does not officially support JBOD in Fujitsu 6Gb RAID 0/1 RAID card (D2607) on their PRIMERGY servers, and the JBOD mode is disabled by default. However you can enable it and use disks in JBOD with D2607.
Here is a procedure on how to enable JBOD in D2607.
  1. Power on your PRIMERGY server.
  2. Press the Control and Y keys during the RAID card initializaton (see below) to launch the command line interface.
  3. Run the AdpGetProp command to check the current javascript:;setting.
  4. Run the AdpSetProp command to enable JBOD if it is disabled.
  5. Enter the 'q' key to exit the CLI.
  6. Reboot.

If the drives which you want to use in JBOD are not shown as JBOD drives like "Unconfigured Good", you need to make the drives JBOD.

Please note that, as I said at the beginning, Fujitsu does not support the JBOD mode with the D2607 RAID card. You can enable and use it, but it should be done at your own risk. If you need D2607 JBOD support, please ask your Fujitsu contact for support.

Update on April 11th: I tested the above configuration on a previous generation of Fujitsu servers (S6 generation). I borrowed an S7 server (RX300 S7) with 16 HDDs and D2607, and did the same setting. The system hung when the RAID controller was being initialized.

When I used a later version of unsupported firmware, the system was able to boot with all the 16 drives in JBOD. I could install Solaris 10 and use all the drives in ZFS as JBOD. Therefore the issue would be caused by the Fujitsu firmware.

Good Bye, Folks!

As you may have heard, Fujitsu has completely discontinued Data Center Products and Solutions business in North America on April 1st, 2021. ...
