Each logical partition requires its own save strategy.</p> <p>Here are a few items that should affect how you plan your backup strategy:</p> <ul><li>It is important to remember that each logical partition functions independently of any others. Therefore you cannot perform a single, entire server backup. Instead, you need to back up each logical partition separately.</li> <li>As part of your backup strategy, remember that a processor failure, main storage failure, failure in the primary partition, or disaster shuts down the entire server. This may require you to recover all or some of your logical partitions. Therefore, plan carefully how you use your logical partitions and how often you need to perform a backup of each logical partition.</li> <li>You can generally perform these backups at the same time since each logical partition functions like an independent server. This can reduce the time that is required for performing backups.</li> <li>If any secondary partitions switch a removable media device between themselves, you must back up each of these logical partitions sequentially. You must manually remove and add the removable media device between the logical partitions after each save. Use <a href="../dbp/rbafoopnav.htm">iSeries™ Navigator</a> to change resources for logical partitions.</li> <li>The server automatically maintains the <a href="rzaiubackuppartdata.htm">configuration data</a> for your logical partitions. This data is not saved to or restored from removable media.</li> <li>You should <a href="../rzait/rzaitprintconfig.htm">print your system configuration</a> when you make changes to your logical partition configuration.</li> <li>Any function that requires you to power off or restart the server (like applying program temporary fixes [PTFs]) requires special care. If you need to power off or restart only a secondary partition, then you may safely do it. However, if you need to power off or restart the primary partition, then you need to power off all the secondary partitions <span class="uicontrol">before</span> you perform that function.</li> </ul> </div> <div> <div class="familylinks"> <div class="parentlink"><strong>Parent topic:</strong> <a href="rzaiurzaiu138.htm">Save logical partitions</a></div> </div> <div class="relconcepts"><strong>Related concepts</strong><br /> <div><a href="rzaiubackupbacking.htm">Back up a logical partition</a></div> </div> <div class="relinfo"><strong>Related information</strong><br /> <div><a href="../icbase/iphai/backingupthehmc.htm" target="_blank">Backing up and restoring the HMC</a></div> <div><a href="../icbase/iphat/iphatlparkickoff.htm" target="_blank">Partitioning the server</a></div> </div> </div> </body> </html>
