    Does Linux OS (Centos) update firmware automatically.

    Hi All,

    Thank you in advance.

    I have a server running on Centos OS. recently there was some problem and my IT person informed me that the firmware was automatically updated. basically the RAID controller was updated. I have some questions
    1. Can an OS automatically update firmware.
    2. How can i check when was the firmware updated last.

    I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.
    When the system is updated, if necessary, firmware will be updated also (if available). Can you check? Usually, yes using the command "yum list '*firmware*'". Here is a list of installed firmware in my SL6 (Scientific Linux 6 - like CentOS 6 it is a clone of RHEL 6):

    This provides the versions, but not WHEN it was last updated... I'm not sure if that information is stored anywhere.
    Sometimes, real fast is almost as good as real time.
    Just remember, Semper Gumbi - always be flexible!

    For a system:
    OS, ker|rel, machine: Linux, 2.6.32-220.17.1.el6.x86_64, x86_64
    Distribution        : CentOS release 6.2 (Final)
    The command:
    yum history packages-info '*firmware*'
    produces some information. For example, an excerpt:
    Transaction ID : 3
    Begin time     : Fri Jun  8 10:21:54 2012
    Package        : kernel-firmware-2.6.32-220.17.1.el6.noarch
    State          : Update
    See man yum, search for history to see details.

    Best wishes ... cheers, drl
