IBM SSA Disk Drive Microcode
How to apply SSA Drive Microcode Updates from DOS
Last Updated : 28th May 2002


You should run issaddld.exe with all the .dl drive microcode
files. This will ensure that all drive types get updated to the
latest levels.

Note : If the downloader does not find any drives of one type
you can skip future downloads of that type, but it is
recommended you apply the microcode as described below. Please
read the WARNINGS below.

You can check the level and type of your drives by running your
native configurator and checking each drives PARTNO and ROS/RAM
(or LEVEL) fields in the VPD. The part number will tell you which
type of drive you have, usually something like DCHC09C which
corresponds to a 9.1 Gb DCHC drive etc The level field contains
the current microcode level e.g 9393.

*** WARNINGS *** READ BEFORE APPLYING DRIVE DOWNLOADS ***
*********************************************************

WARNING : Do not download microcode to disk drives that are in
          use. Ensure that no I/O operations are in progress to
          the disk drive and that any disk drive that is a
          download target is not being used by any other system
          unit.

WARNING : Since I/O operations may be performed by a RAID adapter
          without any host system involvement, for example, when
          rebuilding an array, you must avoid downloading to disk
          drives that are members of an array that is in the
          rebuilding state.




The following sections describe how to apply drive microcode via
DOS. You should download all the DOS Drive microcode diskette
images to update all drive types. These are available from :

 http://www.storage.ibm.com/hardsoft/products/ssa


Boot the server from this diskette and at the a:\ prompt run :

  dir

Note the names of the .dl files, and run one of the following
pairs of commands - depending on which .dl files are contained
on this diskette.

  issaddld DGHC9911.dl
  issaddld WAAH9911.dl

Insert the next diskette and run :

  issaddld DFHC8877.dl
  issaddld DCHC9595.dl

Insert the third diskette and run :

  issaddld DRVC0023.dl
  issaddld DRHC0012.dl

Apply drive microcode from any other diskettes in this package
in the same way.

All drives should now be up to date.
