Task 6: Create an SPR Log File
requisite, verify the order of installation. See the DSM/SCM User’s Guide for
information on using the DSM/SCM product to install SPRs.
When installing an individual SPR, any steps to be carried out before and after those
associated with DSM/SCM are listed in the “Installation Instructions” section of the
SPR’s softdoc addendum. For example, for some products, it is necessary to save
subsystem configuration files before they are replaced during the installation. On
occasion, microcode of a certain version must be downloaded before the DSM/SCM
steps can occur.
The installation instructions in the “Installation Considerations” section of the softdoc
addendum are relevant only to the SPR being documented. You must use judgment in
composing aggregate instructions to install multiple SPRs simultaneously (whether
dependent on each other or not).
Task 6: Create an SPR Log File
Create an SPR log file to maintain an accurate and current software profile on your
system.
Be sure to document the reasons for your decision to install an SPR. Maintaining an
SPR log file makes it easier to process new SPR information as it becomes available
and is invaluable the next time you plan to move to a new RVU (see Keeping Track of
SPRs on page 3-15).
Caution. Use the DSM/SCM product to properly install an SPR. Using other ways to install
NonStop Kernel operating system software (for example, copying files into the SYSnn
subvolume) can have serious consequences later. The DSM/SCM product maintains a
database that describes the software it installs, and bypassing it invalidates its database and
can cause subsequent executions to produce undesirable results.
