What you must ensure is that all the VMs are HA compliant (SimpliVity HA, the primary and secondary replicas are available and updated). This is what the Upgrade Manager Guide states:</P><P><SPAN class="">Check the HPE SimpliVity federation</SPAN><BR /><SPAN>Before you begin the upgrade process, check the following federation items:</SPAN><BR /><SPAN>•</SPAN> <SPAN>HPE OmniStack hosts reside in clusters.</SPAN><BR /><SPAN>•</SPAN> <SPAN>Ensure that the clusters are configured appropriately to allow for running guest migration from the hosts being upgraded.</SPAN><BR /><STRONG><SPAN class="">For example, disable <SPAN class="">vSphere</SPAN> HA, or define vSphere HA admission control settings that will not interfere with guest</SPAN></STRONG><BR /><SPAN><STRONG>migration</STRONG>. For more details, refer to the</SPAN> <SPAN class="">HPE OmniStack for vSphere Administration Guide</SPAN><SPAN>.</SPAN><BR /><SPAN>•</SPAN><STRONG> <SPAN class="">Verify that the guest virtual machines in the clusters you want to upgrade show a status of "Yes" for Storage High Availability</SPAN></STRONG><BR /><STRONG><SPAN class="">(HA) compliance by checking the virutal machine view in vSphere Client.</SPAN></STRONG></P><P><STRONG><SPAN class=""><A title="HPE OmniStack 4.2.0 for vSphere Upgrade Guide" href="https://support.hpe.com/hpesc/public/docDisplay?docLocale=en_US&amp;docId=a00131392en_us" target="_blank" rel="noopener">HPE OmniStack 4.2.0 for vSphere Upgrade Guide</A>&nbsp;</SPAN></STRONG></P><P><SPAN class="">Upgrade Manager will evacuate all VMs from the host when performing the upgrades. If DRS is not licensed then the user has to perform this operation manually. </SPAN></P><P><SPAN class="">Hope it helps.&nbsp;</SPAN></P> Fri, 23 Feb 2024 13:40:13 GMT https://community.hpe.com/t5/hpe-simplivity/hpe-simplivity-upgrade-for-two-node-cluster/m-p/7207226#M4597 gustenar 2024-02-23T13:40:13Z
