8 Tips for Maintaining Licensed Internal Code

Make sure you keep track of new releases, updates and emergency fixes to HMC

code. You can do this in one of two ways:

• Sign up for the technical support subscription service to receive

emails when updates become available on the web

• Monitor the web manually on a regular basis at

http://www14.software.ibm.com/webapp/set2/sas/f/hmc/home.html

8.1 Code and Resources on the Web

Read the web site carefully. Select the correct HMC version, whichever is

appropriate. There are many resources on this site, such as:

• Links to additional technical information

• Hints and tips

• The latest Command Line Specification (command line reference)

• Order Recovery CDs/DVDs

• Download packages that contain the ISO files needed to burn your own

Recovery media. (Note: this media is bootable.)

• Download updates to HMC code as well as emergency fixes, or order

CDs containing the updates and fixes. (Note: this media is not bootable.)

8.2 Maintain Backups

Maintain a current Critical Console Data backup. If you use Recovery media to

update your Licensed Internal Code to a new release level, make a new CCD

backup after the upgrade process. A CCD backup created at V4R3.0 will not

work on a system that was upgraded to V4R4.0 using a Recovery CD. However,

if you are trying to recover after losing a disk on a system that was updated using

the Corrective Service files, you can use a CCD backup (created at V4R4.0) with

your V4R3.0 Recovery CD.
