PAGE 5
Issue ID Functional Area Description MDT-221465 Hardware Prevent an unexpected node reboot caused by a deadlock condition induced by a user service being cleaned up and restarted. MDT-226692 Hardware A single node reboot occurred when two kernel processes, one executing nvme_timeout and the other executing nvme_remove, attempt to access locked resources at the same time and they deadlock because each process is holding a resource needed by the other process.
PAGE 6
Known Issues The following high severity issues are reported in this release. For a list of the minor issues, see Knowledge Base article SLN320772 PowerStore Release Notes – Minor issues at: https://www.dell.com/support/article/SLN320772.

PAGE 7
Issue ID Functional Area Description Workaround/Resolution MDT-220994 Data Protection The replication session may not be deleted once a Protection Policy is unassigned from the storage resource. To delete the replication session, do the following: 1. If Protection Policy is not assigned to the storage resource, reassign the the same Protection Policy that was previously assigned to the storage resource. 2. Unassign the Protection Policy from the storage resource.
PAGE 8
Issue ID Functional Area Description Workaround/Resolution MDT-236192 Internal Migration Internal migration of imported volumes from a remote system using the nondisruptive import variant does not redirect a host application running on either Linux/Windows or VMware to the associated PowerStore volumes. To ensure a successful migration between appliances for imported volumes, reconfigure the host application to PowerStore volume before initiating intra-cluster migration.
PAGE 9
Issue ID Functional Area Description Workaround/Resolution MDT-156905 Install or Upgrade After a software update, the NAS servers may not fail back automatically to the original node. Manually fail back the NAS servers from PowerStore Manager. MDT-135505 Install or Upgrade Drive firmware updates may not get applied to a single or few drives within the appliance. This may occur because of a timing issue between the two nodes in the appliance.
PAGE 10
Issue ID Functional Area Description Workaround/Resolution MDT-130894 PowerStore REST API Two invalid resource_types, FEPort and Initiator, may be returned by the event and alert APIs. Events or alerts with resource_type FEPort or Initiator should ignore the resource_type values. External OpenAPI clients must disable validation for the event and alert APIs with resource_types of FEPort or Initiator.
PAGE 11
Issue ID Functional Area Description Workaround/Resolution MDT-147688 Storage - File SMB clients cannot connect to a NAS server when the NAS server name is more than 15 characters. This is because by default the SMB server computer name takes the NAS server name. Set the NAS Server name with 15 characters or less or set the SMB server's computer name with 15 characters or less. To modify the computer name, select all the characters in PowerStore Manager, and type the new name.
PAGE 12
Issue ID Functional Area Description Workaround/Resolution MDT-210085 Storage - File Unable to add a Tree Quota to a File system because there the description is too large (more than 512 bytes). Add a shorter description to the Tree Quota. MDT-195652 Storage - File Unable to remove the description from an NFS Export. To change the description, overwrite the current description with a blank character space. Save the NFS Export with no description, then go back and update the description again.
PAGE 13
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. When the heartbeat is not received in the 60-second timeout interval, the host is considered as not responding, and the host is marked as disconnected.
