Deployment Notes / Limitations:
- Wake on LAN (WOL) will not be supported on the ReadyNAS 4220 at this time using the 10GbE port. Use the 1GbE port for WOL.
- There is no error message presented in the local admin GUI when the USB key is missing from the system for encrypted volumes. The LCD display will present a message that the USB key is missing.
- If the USB key is missing for encrypted volumes, the power LED will blink for 10 minutes. If no USB key is plugged in within 10 minutes, the encrypted volume won't be mounted and will be inactive.
- If a Flex-RAID volume has been expanded, the volume cannot be switched back to X-RAID mode..
- If you wish to remove a USB storage device, you should first eject the drive in the local admin GUI before removing the USB device from the ReadyNAS to prevent errors on the file system of the USB device.
- ReadyNAS 102, 104, and 2120 only support creating iSCSI LUNs 8TB and smaller.
- ReadyNAS devices updated to ReadyNAS 6.4.1 can downgrade to 6.4.0 but cannot be downgraded to earlier version..
- When initially upgrading your ReadyNAS to 6.4.1, a quota scan takes place during boot. This may cause the unit to take some time to do a scan, depending on your volume usage. Allow some time when restarting your ReadyNAS for the first time after upgrading.
About Network-Attached Storage Updates:
Upgrading the Network-Attached Storage (NAS) firmware can improve the system’s overall performance, stability, and security by adding various fixes for related issues, enhancing existing features (or adding support for new ones), or updating different applications.
Due to the high number of NAS manufacturers, as well as network storage types, installing a new firmware might not be always as easy as it appears – and not too safe either. Failing to perform a software update can cause serious malfunctions to the network storage.
So, before you even consider applying this release, carefully read the installation guide and initiate the process only when you have understood and completely familiarized yourself with all the steps.
Moreover, it would be best if you take into account using a UPS unit (Uninterruptible Power Supply) to perform this task, because no power disruption should affect the upgrade.
With all these aspects in mind, after you have read the installation guide, click the download button to apply this firmware version to your NAS. Remember to check back with our website in order to stay up to speed with the latest releases.
