Enhancements

Fixed Issues

• Fixed an uncommon issue where mapping a Fibre Channel LUN to a target or enabling a mapped Fibre Channel LUN resulted in an error message.
• Resolved an issue where FTP service would become enabled after a high availability operation even though the service was previously disabled.
• Fixed a rare issue where a "Failed to restart" message might incorrectly appear while storage controller A was in the process of restarting.
• Resolved an issue where if a high availability operation started while a file with an overly long name was being transmitted via SMB, the transmission might terminate and fail.
• Fixed an issue where Fibre Channel service became unavailable after replacing a Fibre Channel host bus adapter.
• Fixed a rare issue where after a NAS firmware update, Fibre Channel LUNs on the NAS might appear as RAW partitions on Windows.
• Fixed an issue where running a SnapSync job and scrubbing the destination storage pool at the same time might cause the destination NAS to crash.
• Resolved a rare issue where an SMB client might suddenly get disconnected and could not reconnect unless the NAS or SMB service was restarted.
• Fixed an issue where after one of the controllers was removed, the High Availability app might sometimes incorrectly report errors for healthy components on the other controller.
• Fixed a rare issue where after replacing a disk in a RAID group, the RAID group might still remain in degraded mode.
• Several minor bug fixes.
