Check and correct any problems associated with points 1, 2, and 3. If everything
is correct in these areas, then proceed to the next section to find out how to
resolve problems with the SDR.
5.3.6 Applying the System Partitioning
The key step at this point is to ensure that all affected nodes are shutdown. This
is critical to the health of these nodes in the newly-partitioned environment.
Shutting them down is the best way to guarantee that all the daemons and files
will be configured correctly in the new partitions. Shut the nodes down in the
correct manner according to the normal working procedures on the system (that
is, in the correct order from the spmon GUI or the command line).
When the
tasks are carried out:
If the apply fails, then record the error message that appears on the SMIT
screen. In order to debug this further, read the following sections about the SDR
and heartbeat subsystems.
5.3.7 Validating the Partitions and Restoring the SDR
The option remains to restore the SDR that was archived earlier in the
procedure, but it is worth understanding why the apply failed in case the same
problem occurs the next time you attempt to implement System Partitioning.
To restore the SDR, go to the SMIT menu Restore System Partition
Configuration, list the archived files, and select the appropriate backup or
archive to restore. This will run the following command:
# /usr/lpp/ssp/bin/sprestore_config
This script restores the original SDR and reverses the actions carried out in the
apply of the partitions. For example, it will stop and remove the multiple
daemons.
Even if the apply was successful, it is still a good idea to run the following
command to verify that the partitioning configuration is good in the SDR before
the affected nodes are rebooted:
# splstdata -p
The
the SDR was updated correctly, but it can be run manually from the command
line as a final check.
