Task 5: Install the SPRs

Review the README file for the RVU. Install additional SPRs in a timely manner to

avoid encountering known problems that have already been resolved. When you install

an SPR, make sure you have all relevant information accumulated and examined

during your review and research phases. If you plan to install more than one SPR or

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. 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 section of the softdoc 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 3-12).

Caution. Use the DSM/SCM product to properly install an SPR. Using other ways to install

NonStop 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.
