This appendix contains instructions for returning your system software to a
previous release (backdating). This chapter describes general backdating methods
that will work in most cases.
WARNING! If you are on an N-Class or A-Class system, you cannot backdate
to software before 7.0. If LDEV1 > 4 GB, you must reinstall with the previous
build; you cannot backdate.
CAUTION: Perform a backdate when you have updated your operating system
version and have serious problems. Only do this under direction from your
HP representative or Response Center.
Do not use the directions in this appendix to backout patches.
If you applied patches using staging areas, refer to
Appendix G HP Stage/iX Reference for directions
on backing out of a staging area.
If you applied patches separately from a system software update,
refer to the HP Response Center, if you have a software support
contract, or your HP representative for directions on backing out
patches.
If you applied patches as part of a system software update, follow
the procedures in this appendix. The patches will be removed as part
of the backdating process.
This appendix is divided into the following sections:
Planning Your Backdate
Securing Your System
Performing the Backdate
Method 1: Using a CSLT (Customized System Load Tape)
