This will interrupt IO servicing on the node for approximately 2 minutes until the service is started. IO to the other node is unaffected. After mapping a LUN or creating a VM, the LUN or VM appears correctly, but it is inaccessible to hosts. Unable to delete a volume group after deleting a replication session, due to undeleted replication session system snapshots. In a Unified appliance cluster, after the system exits from an out of space scenario, some of the NAS Servers will not return to Read-Write mode when the controlpath restarts. While trying to create or delete a snapshot the following error message was returned: "Addition [or deletion] of NFS Export failed due to [The path [path_name] was not found on the system and cannot be exported.]" 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. The "NAS node is down," major alert may be seen after changing the Cluster MTU value. Changing the MTU value may cause degradation or disruption in NAS (file) services. Under rare circumstances, NAS services could be disrupted, if the appliance is close to reaching the maximum used data capacity. Unable to remove the description from an NFS Export. None Unmap the non-working LUN and map it again. For VMs, delete the non-working VM and recreate it. Contact your service provider for the procedure to delete the snapshots. Contact your service provider. Wait for some time and try the action again. 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. Wait for the alert to clear before performing any further NAS (File) operations. Take one of the following actions on the appliance on which the NAS service is installed: add capacity to the appliance (for example, add drives or expansion enclosures), increase free capacity on the system (for example, deleting unused snapshots, volumes) , or migrate data off the system. 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. Known Issues 13
