Known Issues Issue ID Functional Area Description Workaround/Resolution MDT-133408 Data Protection When a volume group is created with member volumes and is protected by a protection policy that includes a replication rule, the volume group members may be delayed in being replicated to the remote system until the next RPO cycle. The default replication rule RPO value in PowerStore Manager is 1 hour, but it can range from 5 minutes to 24 hours.
Known Issues 8 Issue ID Functional Area Description Workaround/Resolution MDT-117061 Hardware When beginning cluster creation, the hardware status is incorrectly indicated as not configured for clustering. Wait a few minutes and try again. MDT-137439 Import If an import from a Unity or VNX2 system to PowerStore is cancelled by the user or fails for some reason, it is possible that subsequent attempts to import the volume will also fail.
Known Issues 9 Issue ID Functional Area Description Workaround/Resolution MDT-155853 Monitoring If there is a critical capacity based forecasting alert, a migration recommendation repair flow can be used to migrate storage to another appliance. It is possible that after migration completes, the daily forecast used to trigger the alert will not be updated on the source appliance and the alert will not be cleared until the next daily forecast.
Known Issues Issue ID Functional Area Description Workaround/Resolution MDT-142069 PowerStore Manager(GUI) There are situations when the system is Out of Space where the UI is unable to update its statistics. This situation will be evident by a red banner on the top of the screen. You may see objects in the UI that are incorrectly displayed as "0 MB/GB/TB" due to the inability for the UI to query for system statistics.
Known Issues Issue ID Functional Area Description Workaround/Resolution MDT-121784 Storage - File After a NAS server is successfully deleted, the alerts against the deleted child objects of the NAS server such as DNS servers, file systems, NFS exports, or SMB shares, are not cleared. Review the alert details, to confirm the alert is for a child object of a successfully deleted NAS server. Once confirmed, ignore or acknowledge the pending alert.
Known Issues Issue ID Functional Area Description Workaround/Resolution MDT-142317 Storage - File After configuring and running I/O operations to SMB shares and NFS exports events such as an appliance or NAS server reboot, or a file system unmount or remount may cause some negative values to appear in the saved file system performance statistics exported from PowerStore Manager (GUI).
Known Issues Issue ID Functional Area Description Workaround/Resolution MDT-149396 Support If an event or issue abruptly interrupts the node while the node, appliance, or cluster is powering off, the node may not complete powering off and a reboot may occur instead. Try powering off the node, appliance, or cluster again. MDT-148608 SupportAssist Attempts to upload Support Materials fail. Support Assist is unable to upload files when there is insufficient free space in the system partition.
Known Issues Issue ID Functional Area Description Workaround/Resolution MDT-156507 Virtualization In high scale VMware vSphere environments, where the ESXi hosts and vCenter server are highly loaded (for example, simultaneous powering on a large number of VMs), heartbeat messages sent by the ESXi hosts to the vCenter server may not be delivered in time.
Known Issues Issue ID Functional Area Description Workaround/Resolution MDT-119414 Virtualization Deploying a VM fails, and checking the vvold.log vCenter log file reveals the following messages: Try to deploy the VM again.
