Today I had to update firmwares on a bunch of servers. The firmware update could be done online, only a (manual) reboot was needed afterwards. The updates can be downloaded as rpm’s, so here’s what I did:

  • copy all the rpm’s in a single nfs location
    • (you could put them on a yum repo, but this actuall complicates matters imho)
  • make a script that installs the rpm, runs the scexe, removes the rpm
    • HP updates each have a single scexe which actually updates the firmware
      • the rpm puts it in /usr/lib/${arch}-linux-gnu/hp-scexe-compat/CP######.scexe
  • run the script on every server sequentially
    • (if something goes wrong, not all servers go down at the same time ;-))

The script (you will probably need to change the RPM_DIR location):



for RPM in $RPM_DIR/*.rpm
        NAME=$(rpm -qp --queryformat '%{NAME}\n' $RPM 2>/dev/null)
        SCRIPT=$(rpm -qpl $RPM 2>/dev/null | grep hp-scexe-compat/.*\.scexe)
        echo "Parsing: '$RPM'; name='$NAME', script='$SCRIPT'"
        if [[ -z "$SCRIPT" ]]
                echo "No scexe '$SCRIPT' found in rpm '$RPM'; no idea what to do ..."
                rpm -ivh $RPM
                echo "Running '$SCRIPT' from '$NAME'..."
                $SCRIPT -s
                echo "Done with '$NAME'; uninstalling:"
                rpm -evh $NAME
