eLux partitions
An eLux device's flash memory is generally divided into three or four partitions when eLux is installed. Each partition is reserved for a dedicated purpose and is only touched when you perform special tasks that are related to this partition.
All partitions are created during a recovery installation.
| Partition | Requires | Purpose | Recreated with | Other |
|---|---|---|---|---|
| System | Reserved for the firmware (software packages) | Scout Update command with option Format system partition before update | Size for eLux RP 6 2104 LTSR and earlier versions: 1,77 GB / 1,84 GB with/without encryption Size for eLux RP 6 2107 and later versions: 2,35 GB / 2.41 GB with/without encryption |

| Boot | only UEFI and USB | Boot section | – | |
| Setup | Device configuration Local application definitions |
Factory reset command | Does not affect the system partition with installed firmware | |
| Update | 4 GB flash memory | Software delivery in advance (before firmware update) via Scout command or notification Signature check for eLux software packages Devices with update partition can be used as Dynamic Proxy (Provider) for firmware updates. |
Scout Delivery command with option Format update partition before delivery | The size of the update partition complies with the storage space provided. The update partition is no larger than the storage space provided. Devices with less than 4 GB flash memory are not provided with an Update partition. |
In the Scout Console, in the Properties window of a device, the system, setup and update partitions are listed including their sizes.
Extended system partition starting with eLux RP 6 2107
When you perform an update installation or a new installation (recovery) to eLux RP 6 2107 or later, the system partition is created with 2,35 GB / 2.41 GB (with/without encryption) instead of the previous almost 2.0 GB. This creates more space for the firmware and allows larger images to be used.
-
Update installation
An update installation (firmware update) is still based on the previous partition sizes. The image size is thus still limited to the earlier values. Afterwards, the extended system partition is available and you can install images that may be up to 2.35 GB / 2.41 GB in size. This means, to install larger images on the freshly resized partition of the devices, a second firmware update is required.
-
Recovery installation
Provided an up-to-date recovery system is available, with a PXE or USB recovery installation the system partition can be partitioned to the new size directly during the installation process and a larger image with up to 2.35 GB / 2.41 GB can be written in the same process. A new installation or recovery installation thus allows the partition to be resized and used in one step.
Downgrade
To downgrade devices with the extended system partition (eLux RP 6 2107 or later) to an earlier version that only supports the previous system partition with less than 2 GB, you will have to go back to eLux RP 6 2104 LTSR.
We therefore recommend that you update test devices to eLux RP 6 2107 or later as the first step to thoroughly test functionality.
