Installing Power Subsystem Firmware and System Firmware

Atention: 9125-F2A servers should be evaluated for ECA845 installation prior to performing firmware upgrades. Contact your service provider for more information about ECA845. If firmware must be upgraded prior to the installation of ECA845, use the following special instructions:

Firmware updates should be performed on an entire Managed Frame and all Managed Systems
contained in that frame at one time.  The following instructions can be used to update
one Managed Frame and all Managed Systems that it contains.  The instructions can be
repeated as many times as needed until all Managed Frames have been updated.

1) Power off all Managed Systems in the Managed Frame

2) Reinstall the current firmware level on all Managed Systems in the Managed Frame:

   The following command can be used to determine the current firmware level:

      lslic -t sys -m <managedsystem_1> -F activated_level

   The following command will retrieve and reinstall the current firmware level on
   one Managed System:

      updlic -o a -m <managedsystem_1> -t sys -l <current_fsp_level> -r <repos>

      <current_fsp_level> is the level determined with the lslic command.

      <repos> is the location of the firmware such as "-r dvd", "-r ibmwebsite", etc.
      Additional parameters might be required, depending on the repository selection.
      If the firmware has already been retrieved to the HMC, the HMC hard drive (-r disk)
      should be used as the repository.

   After the firmware has been retrieved to the HMC, the HMC hard drive (-r disk) should
   be used as the repository to update the remaining Managed Systems:

      updlic -o a -m <managedsystem_2> -t sys -l <current_fsp_level> -r disk
      updlic -o a -m <managedsystem_3> -t sys -l <current_fsp_level> -r disk
      ......
      updlic -o a -m <managedsystem_N> -t sys -l <current_fsp_level> -r disk

   These commands can be run in the background in parallel to speed up the processing.

   Wait for all updlic commands to complete before proceeding to step 3.

3) Install and activate new BPC firmware only (during this step the Managed Systems will
   transition from "Power Off" to "No Connection" and then back to "Power Off"):

   Select 1 Managed System as the target of the updlic command and update BPC firmware.
   The following command will retrieve firmware from the repository and update the BPCs:

      updlic -o a -m <managedsystem_1> -t power -l latest -r <repos> .....

      <repos> is the location of the firmware such as "-r dvd", "-r ibmwebsite", etc.
      Additional parameters might be required, depending on the repository selection.
      If the firmware has already been retrieved to the HMC, the HMC hard drive (-r disk)
      should be used as the repository.

4) Wait for all Managed Systems to return to "Power Off" state.

5) Install and activate new firmware on all Managed Systems in the Managed Frame.

      updlic -o a -m <managedsystem_1> -t sys -l latest -r <repos> .....

      <repos> is the location of the firmware such as "-r dvd", "-r ibmwebsite", etc.
      Additional parameters might be required, depending on the repository selection.
      If the firmware has already been retrieved to the HMC, the HMC hard drive (-r disk)
      should be used as the repository.

   After the firmware has been retrieved to the HMC, the HMC hard drive (-r disk) should
   be used as the repository to update the remaining Managed Systems:

      updlic -o a -m <managedsystem_2> -t sys -l latest -r disk
      updlic -o a -m <managedsystem_3> -t sys -l latest -r disk
      ......
      updlic -o a -m <managedsystem_N> -t sys -l latest -r disk

   These commands can be run in the background in parallel to speed up the process.

   Wait for all updlic commands to complete before proceeding to step 6.

6) Power on the Managed Systems

3.0 Firmware Information and Description

Use the following example as a reference to determine whether your installation will be concurrent or disruptive.

Note:  The file names and service pack levels used in the following examples are for clarification only, and are not
             necessarily levels that have been, or will be released.

Power Subsystem firmware file naming convention:

     02EPXXX_YYY_ZZZ

NOTE:  Values of service pack and last disruptive service pack  level (YYY and ZZZ) are only unique
within a release level (XXX).  For example, 02EP330_067_045 and 02EP340_067_053 are different
service packs.

An installation is disruptive if:

              Example:  Currently installed release is EP330, new release is EP340                Example:  EP330_120_120 is disruptive, no matter what level of EP330  is currently
                                   installed on the system                  Example:  Currently installed service pack is EP330_120_120 and
                                     new service pack is EP330_152_130

An installation is concurrent if:

              Example: Currently installed service pack  is EP330_126_120,
                                 new service pack is EP330_143_120.

4.0 How to Determine Currently Installed Power Subsystem Firmware Levels

You can view the frame's current firmware level on the Advanced System Management Interface (ASMI) Welcome pane.  It appears in the top right corner.   Example:  EP330_029.

5.0 Downloading the Firmware Package

Follow the instructions on the web page. You must read and agree to the license agreement to obtain the firmware packages.

Note: If your HMC is not internet-connected you will need to download the new firmware level to a CD-ROM or ftp server.

6.0 Installing the Firmware

The method used to install new firmware will depend on the release level of firmware which is currently installed on your server. The release level can be determined by the prefix of the new firmware's filename.

Example: EPXXX_YYY_ZZZ

Where XXX =  release level
