PRODUCT:  
    General Parallel File System for Linux

DESCRIPTION:  
    The update images listed below and contained in the tar image
    with this README are maintenance packages for GPFS.  The update
    images are a mix of normal RPM images that can be directly applied
    to your system and one rhmask image that must first be converted
    to an RPM image.  

    The rhmask image conversion requires a prior level of GPFS.
    Thus this update is limited in usefulness to installations that
    already have the GPFS product.  Contact your IBM representative 
    if you desire to purchase a fully installable product that does 
    not require a prior level of GPFS.

    Once the rhmask image conversion is done, and all RPMs are 
    installed, you have successfully updated your GPFS product.

INSTRUCTIONS:

    1. Ensure the rhmask command is installed on your Linux machine.

           rpm -q rhmask

       Install it from your Linux distribution media if it is not 
       already present.

    2. Place your prior version of the gpfs.base rpm image and 
       this update's gpfs.base rhmask images in a common directory.  

       To upgrade from version 1.2-0 of GPFS to 1.2.0-2 
       of GPFS you should have the following images.

           gpfs.base-1.2-0.i386.rpm
           gpfs.base-1.2.0-2.i386.rhmask.1.2-0

       To upgrade from version 1.2.0-1 of GPFS to 1.2.0-2 
       of GPFS you must have the following images.

           gpfs.base-1.2.0-1.i386.rpm
           gpfs.base-1.2.0-2.i386.rhmask.1.2.0-1

    3. Run the rhmask command to produce an RPM image for
       gpfs.base.

           rhmask gpfs.base-1.2-0.i386.rpm  \
                  gpfs.base-1.2.0-2.i386.rhmask.1.2-0
       or
           rhmask gpfs.base-1.2.0-1.i386.rpm  \
                  gpfs.base-1.2.0-2.i386.rhmask.1.2.0-1

       The output from this command will be latest gpfs.base rpm image.
     
    4. Place the newly created RPM image for gpfs.base with all 
       other RPM images in this update in a common directory.  
       The list of RPM images in this directory should now be 

           src-1.1.1.11-0.i386.rpm
           rsct.basic-2.2.1.11-0.i386.rpm
           rsct.core-2.2.1.11-0.i386.rpm
           rsct.core.utils-2.2.1.11-0.i386.rpm
           gpfs.gpl-1.2.0-2.i386.rpm            
           gpfs.base-1.2.0-2.i386.rpm

    5. Follow the installation and migration instructions in your 
       GPFS Concepts, Planning and Installation Guide.

       These steps are minimally:

       a) Stop GPFS on all nodes in the nodeset.

       b) Upgrade GPFS using the RPM command on all nodes in the nodeset.

              rpm -U src-1.1.1.11-0.i386.rpm
              rpm -U rsct.basic-2.2.1.11-0.i386.rpm
              rpm -U rsct.core-2.2.1.11-0.i386.rpm
              rpm -U rsct.core.utils-2.2.1.11-0.i386.rpm
              rpm -U gpfs.gpl-1.2.0-2.i386.rpm            
              rpm -U gpfs.base-1.2.0-2.i386.rpm

       c) Check the GPFS FAQ to see if any additional images or patches 
          are required for your Linux installation.

          http::/www.ibm.com/servers/eserver/clusters/software/gpfs_faq.html

       c) Recompile any GPFS portability layer modules you may have 
          previously compiled.  The recompilation and installation
          procedure is outlined in the following file.

             /usr/lpp/mmfs/src/README
