If you have mirrored disks and users are logged on, do not run SYSINFO. When you can access the system,
verify that you have a current version of SYSINFO on your system and keep your listing.
18. Plan for downtime.
Most of the tasks described in this manual require that you shutdown your system. Plan for this
downtime. DO NOT SHUTDOWN your system until it is necessary. Each task checklist indicates when
the system will be shutdown. Perform all the other steps for the task while your system is up.
To estimate the amount of downtime, review the steps you need to perform after the system is shutdown.
Where possible, an estimate of time is provided. Record the amount of time for the individual steps and
add it up. This will give you a very rough estimate of the amount of system downtime you will require.
The amount of time listed is based on small and low-end machines. Actual time values can be about
one-half of the time listed.
19. If you are using HP Stage/iX, be aware that not all patches are stageable.
At the time of release 7.5, Stage/iX cannot handle patches which involve System configuration files,
MMSAVE.MPEXL.SYS, nonsystem volume set files, and patches with files that contain jobs that are
streamed during patch installation. During the process, Stage/iX will identify which patches are
stageable.
20. If you are using HP Stage/iX to apply patches to your system, remove old stages BEFORE
applying the new release.
Since the process installs a new operating system, you must uninstall HP Stage/iX and/or remove all of
the old stages BEFORE applying the factory SLT.
Uninstalling HP Stage/iX deletes all staging areas and all files and directories that HP Stage/iX has built.
To uninstall HP Stage/iX:
:STAGEMAN
STAGEMAN>UNINSTALL
