Issue ID MDT-417339 MDT-401600 MDT-397046 MDT-346158 MDT-337169 MDT-265301 MDT-170949 MDT-164726 Functional Area Description Workaround/Resolution Install or Upgrade Install or Upgrade Install or Upgrade Install or Upgrade Install or Upgrade Install or Upgrade Install or Upgrade Install or Upgrade Pre-upgrade health checks (PUHC) sometimes fail with a "failed_to_get_free_size" error on a PowerStore 500T cluster even when there is no underlying issue with space on the system. If the healthcheck package was uploaded on the PowerStore cluster before a new appliance was added to the cluster, healthcheck package is unable to run for the newly added appliance. If the ESXi host is rebooted outside of the Maintenance Mode between the ESXi upgrade and the PowerStore X model OS upgrade from 2.0.x.x to 2.1.1.x, the PowerStore X model virtual machine (VM) will not startup automatically, and the PowerStore X model VM will require a manual recovery. If a drive failure occurs and the data path unexpectedly restarts during a failed PowerStore software upgrade, the DRE rebuild feature might become disabled, which prevents the PowerStore software upgrade from being retried. NAS services might fail to start during the initial installation and configuration of PowerStore appliances or during a PowerStore software upgrade. When performing a software upgrade on a PowerStore T model appliance running in Unified mode, the inter-node iSCSI connection might fail when one node is rebooted, which can cause the NAS to panic. Running PowerPath 7.1 and earlier on a Linux host causes an I/O error during the software upgrade of PowerStore OS 1.0 to PowerStore OS 1.0.1. If the Pre-Upgrade Health Check fails during an upgrade from PowerStore OS 1.0 to PowerStore OS 1.0.1 or later, clicking the failed operation link under Recent activities might result in an error because of a localization issue with the event message. Rerun the Pre-upgrade health checks (PUHC). Install the same healthcheck package again. Contact your service provider. Contact your service provider for assistance with reenabling the DRE rebuild feature on the PowerStore cluster. If NAS services fail to start during the initial installation and configuration of PowerStore appliances, try to install NAS again as described in step 4 of the Dell Knowledgebase 000130232: "PowerStore Manager displays 'NAS Installation has failed' when trying to configure PowerStore appliance(s)." If NAS services fail to start during a PowerStore software upgrade, contact your service provider for assistance. Allow NAS-HA to take care of uninterrupted NAS operations during a software upgrade. If data unavailability occurs after the software upgrade is complete, contact your service provider. Apply the next/upcoming PowerPath 7.1 patch, and then run the PowerStore software upgrade to avoid the I/O error. None Known Issues 25
