Important Notes
For the best experience and optimal system performance, we recommend updating all available applications in the App Center after updating the firmware.
Security Updates
Applied multiple security updates to further enhance system security.
Enhancement
Added warning messages for immutable snapshot restrictions to help users understand the limitations when protected snapshots exist.
The system now requires Secure Deletion USB key verification before deleting a LUN that contains unexpired Immutable Snapshots.
Added an alert and guidance flow to Storage Manager when removing a shared folder from Control Panel that is protected by unexpired immutable snapshots or WORM shared folders.
Added an alert for active immutable snapshots and WORM shared folders when users attempt to reinitialize the NAS.
Added instructions and guidance in Storage Manager for various scenarios when a shared folder or a pool contains WORM shared folders or immutable snapshots.
Added support for Secure Deletion. Administrators need USB key files to delete the following items: (1) Enterprise WORM shared folders (2) LUNs or shared folders that contain or immutable snapshots that have not yet expired.
Fixed Issues
Fixed an issue where the Expand Pool wizard would display “RAID Group 1” as “RAID Group 10” when expanding a RAID 10 storage pool.
Fixed an issue where the Expand Pool wizard would allow users to select more than 2 disks when expanding a RAID 10 storage pool. (Expected behavior: users should only be able to select at most 2 disks)
Fixed an issue where an IPv6 static route next-hop was unexpectedly added as default gateway after network link state change.
Fixed an issue where after updating QuTS hero to h6.0.0.3500, a NAS in a non-internet environment would take a while to load the Desktop after user login.
Fixed an issue where app installation would occasionally fail under certain circumstances after updating QuTS hero to h6.0.0.
Fixed an issue where certain Japanese strings in Control Panel, Storage Manager, Snapshot Manager, iSCSI & Fibre Channel incorrectly aligned punctuation marks and some longer menu items were truncated.
Fixed an issue where the SnapSync page would become blank if a SnapSync job name contained more than 10 non-English characters.
Fixed an issue where the NAS would stop responding under a heavy NFS workload.
Fixed an issue where users could create two folders whose names only differed in case in the Home folder via SMB.
Fixed an issue where HybridDesk Station could not be started after updating QuTS hero to h6.0.1.
Fixed an issue that prevented Multimedia Console from functioning normally.
Fixed an issue to improve the stability of Qtier storage pools.
Fixed an issue where users could not upload a folder containing subfolders to the NAS via WebDAV.
