Troubleshoot upgrade issues
Successful upgrades are reported as "Successfully upgraded to version ..." In the event of an
unsuccessful upgrade, the following error messages may help you pinpoint the cause of the
problem.
● Upgrade procedure already in progress
The unit received multiple upgrade requests at approximately the same time. However,
only one request can be handled at a time. The later request receives this error message.
● Invalid firmware file
The unit performs a number of checks to determine the validity of the file. If it finds
problems with the file, such as the file not being a firmware file with a
.sqrfw
extension, it
displays this error message.
● Device hardware is incompatible
If the image identifier of the hardware does not match the image identifier of the firmware
file, this error message indicates that the selected firmware file is not intended for the
unit. In that case, the upgrade procedure is terminated. The fixed image and the upgrade
image stay in the memory of the unit. After a reboot, the unit runs the same image as
before the reboot.
● Firmware file is corrupt
The firmware file contains a CRC error. When this error occurs, the unit reboots
automatically and restarts with the fixed image.
● Rule validation failed
The rules embedded in the firmware file and the result of checking these rules indicate
that the firmware should not be installed on this unit.
