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

                                     new service pack is EP330_152_130

An installation is concurrent if:

              Example: Currently installed service pack  is EP330_126_120,

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

The firmware is located at the web site


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

In the drop-down box, choose the entry for your specific machine type and model.

You may download the individual .rpm and .xml files for Power Subsystem firmware from this location to your server, an ftp server, or a CD-ROM (both files are required).  Make sure the file names have the format 02EP3xx_yyy_zzz, with an extension of .rpm and .xml before copying them to your server, an ftp server or CD-ROM.  If using a CD-ROM, copy the .rpm and .xml files to the CD-ROM using a local CD-ROM burner utility.

Another method is to download the .iso file and create a CD-ROM to use with your HMC.

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.


Where XXX =  release level
