Thank you for your feedback
These release notes cover the requirements, new features, and changes for this release of the Skylight sensor: control firmware version 21.12. Please read all the notes prior to installing this firmware version.
Requirements
This firmware version applies to the following products from Accedian:
| Product Name | Product ID | Firmware Name | Image or Firmware File |
|---|---|---|---|
| Skylight sensor: control | sensor control-1000 | VCX_21.12 | VCX_21.12.0_24458_VMWARE.ova |
| Skylight sensor: control | sensor control-1000 | VCX_21.12 | VCX_21.12.0_24458_KVM.tar.bz2 |
| Skylight sensor: control | sensor control-1000 | VCX_21.12 | VCX_21.12.0_24458_SingleDiskVMWARE.ova |
| Skylight sensor: control | sensor control-1000 | VCX_21.12 | VCX_21.12.0_24458_SingleDiskKVM.tar.bz2 |
| Skylight sensor: control | sensor control-1000 | VCX_21.12 | VCX_21.12.0_24458.afl |
Note: This firmware release includes the images needed to deploy the Skylight sensor: control using a KVM or VMware Hypervisor, as well as the .afl upgrade file that is typically part of a Skylight sensor: control release.
Skylight sensor: control 21.12 requires Skylight orchestrator 20.05 as its minimum. Customers using SD Vision must first upgrade to Skylight orchestrator 20.05 before upgrading to Skylight sensor: control 20.05.
Important Notes
Skylight sensor: control version 21.12 limitation for Skylight orchestrator:
The following Skylight orchestrator functions fail when managing devices using IPv6:
- Backup Job
- Restore function
- FW Upgrade/download jobs, FW upgrade function FW Management page
- SAT report
The reason for this limitation is that the updated DropBear requiring command URLs with [ ] for IPv6 address is not supported in the current Skylight orchestrator release.
Workaround: Skylight orchestrator can manage devices using IPv4, otherwise do not upgrade sensor: control until IPv6 is supported in the next release.
Availability of Skylight orchestrator fix: The next Skylight orchestrator release will support command URLs with [ ] for IPv6 address.
Skylight sensor: control upgrades
In Skylight sensor: control 21.12, any module upgrades from firmware versions previous to VCX 2.2 FWSuite (FWSUITE_VCX_2.2_10190) have been blocked, in order to protect against a potential complete loss of connectivity/functionality that cannot be recovered. In order to upgrade a module from an older FWSuite version, an older version of Skylight sensor: control must be used to first upgrade the module to FWSUITE_VCX_2.2_10190:

| VCX 2.2 | FWSUITE_VCX_2.2_10190 |
Skylight sensor: control upgrade consideration
When upgrading the Skylight sensor: control software, the modules firmware is not upgraded automatically. It is not recommended to operate Skylight sensor: control with a different module firmware version since the functionality is limited to management. The management includes:
- Module discovery
- Connect to module and have a management Link state
- Upgrade module firmware version using feature suite
- Update module interface (IP address, VLAN, and DHCP)
CAUTION: The upgrade process was hardened in VCX 2.7. Under specific circumstance the module upgrade can still fail. This happens if the module management is lost and the module performs an automatic rollback. The module can brick if the power is lost in a critical short time period. This was seen in a lab environment only and never reported by a customer.
Before doing the upgrade, it is recommended to enable Extra Reconnection Delay with the previous release (refer to the Skylight sensor: control User Manual, section 4.3, “Adding Remote Devices” for more details on how to enable Extra Reconnection Delay).
The downgrade is still executed using the previous software that still has the update process deficiencies. The downgrade can still cause remote devices to fail and should be avoided at the exception of VCX 2.5.0.2 and VCX 2.6.0.1 for which the downgrade is supported without issue.
It is not recommended to change any other module configuration when operating with a different firmware version. Changing the configuration could result in unknown behavior. A factory reset using AMD could be required in some cases. In a future release, the Skylight sensor: control software will prevent changing configuration for modules running a different firmware version.
For cases where all modules cannot be upgraded at the same time, it is recommended to run different Skylight sensor: control instances with different software versions. Modules to be upgraded should be moved between Skylight sensor: controls.
When downgrading Skylight sensor: control software, the modules firmware version shall also be downgraded. The downgrade process shall follow these steps in order to successfully downgrade Skylight sensor: control software and modules firmware. Note that downgrades are not recommended (see CAUTION above).
CAUTION: The downgrade is still executed using the previous software that still has the update process deficiencies. The downgrade can still cause remote devices to fail and should be avoided.
Before doing the downgrade, it is recommended to enable Extra Reconnection Delay with the previous release (refer to the Skylight sensor: control User Manual, section 4.3, “Adding Remote Devices” for more details on how to enable Extra Reconnection Delay).
Scenario 1: downgrade using Skylight sensor: control rollback
- The modules firmware must be downgraded first using the newest Skylight sensor: control software.
- Perform Skylight sensor: control rollback.
Scenario 2: downgrade using a different Skylight sensor: control instance
- The modules firmware must be downgraded first using the newest Skylight sensor: control software.
- Delete modules from the newest Skylight sensor: control instance.
- Discover the modules using the older Skylight sensor: control instances.
