Introduction
HP Stage/iX
HP Stage/iX
HP Stage/iX is an operating system facility for applying and managing MPE/iX patches on
your system. Using HP Stage/iX reduces system downtime and provides an easy and
reliable method for backing out patches. Refer to Appendix G , “HP Stage/iX Reference,”
for information on HP Stage/iX commands and staging area handling.
Use HP Stage/iX to place PowerPatch and/or Reactive patches into staging areas on disk
while the system is up, then choose a staging area to use at boot time to apply the patches.
After the patches are applied, they can be backed out at any time through a reboot to the
Base (the version applied by the last tape update). Once you are satisfied with the patches
on the running system, you can commit the staging area to form a new Base while the
system is running (no reboot is needed).
HP Stage/iX has the following three interfaces:
HP Patch/iX
menus
allow you to stage patches to staging areas after HP Stage/iX is initialized
(as well as create CSLT/STORE tapes in the usual fashion). Refer to
Appendix F , “HP Patch/iX Reference,” for information about HP Patch/iX.
STAGEMAN utility allows you to manage your HP Stage/iX environment, and obtain
information about the environment and individual staging areas.
STAGEISL utility is an ISL utility available when the system is down. It contains a
subset of the STAGEMAN functionality, and allows you to recover from most
errors or mistakes.
HP Stage/iX Concepts
Your Operating System (OS) resides in what HP Stage/iX refers to as the Base.
This is the set of files laid down by the last system installation or update (from tape). HP
Stage/iX creates and manages staging areas, which are file containers on disk that hold
versions of files that are different from the Base. A staging area is actually an HFS
directory which holds all the files associated with that staging area. More than one staging
area can exist at a time. Each staging area contains the difference, or delta, between the
Base Operating System and a patched OS.
When a staging area is activated on the next boot, the files in the staging area directory
are moved (renamed) into their natural locations. For example, the staged version of the
NL is moved into NL.PUB.SYS. At the same time, the Base versions of the files are saved in
an HP Stage/iX archive directory. When the staging area is backed out (when the system is
booted back to the Base), the converse takes place, and the system is restored to its
original state.
When an active staging area is committed to the Base, the staging area directory is
deleted, and all archived Base files are purged. The files that were switched into their
natural locations when the staging area was activated remain there as part of the new
Base. This releases any disk space that was used by the staging area.
HP Stage/iX (with the help of HP Patch/iX) allows new patches to be staged and applied in
