Flow Chart Of The System Partitioning Process - IBM RS/6000 SP Problem Determination Manual

Figure 64. Flow Chart of the System Partitioning Process
The 2nd, 3rd, and 4th steps in the SMIT menu (Select System Partition
Configuration, Display Information for Given Configuration or Layout, and Select
System Partition Layout) are represented by the single box list/select configs in
the flow chart. These SMIT menus can be used to assist in deciding how to
partition the system, but system partitioning can also be done manually by
following the guidelines regarding the directory structure previously given in this
chapter.

5.3.3 Archiving the SDR
Always begin the System Partitioning by archiving the SDR. It is possible to
return to the original configuration by reapplying it, but this could involve a
considerable amount of work and requires detailed knowledge of System
Partitioning and the related subsystems. Archiving the SDR can be done from
SMIT or the command line. Either way, the command run will be:
# /usr/lpp/ssp/bin/SDRArchive
Make a note of the name of the archive, because this command may have been
run multiple times, leaving several files in the following directory:
/spdata/sys1/sdr/archives
It should be easy to identify the backup just taken, because the filename is
appended with the time. For example:
backup.96124.0926
After the backup part of the name, the year is listed, followed by the Julian day
(that is, the number of days into the year), and then the time as the suffix.
