Current Series Release Notes¶

4.4.0-1¶

Adds an extra check for cases where the BMC provides a SettingsObject URI through @Redfish.Settings but this URI does not allow setting boot related attributes. Prior to sending a PATCH request to SettingsURI, a GET request is issued to verify if it contains the attributes to be updated. In case these attributes are missing, the request is made against System URI instead. Issues such as the one addressed with this change usually manifest themselves with a Redfish response containing an error message similar to the following: MessageId: Base.1.8.PropertyNotWritable, Message: The property BootSourceOverrideEnabled is a read only property and cannot be assigned a value.

Adds two new configuration options: server_side_retries allows to set a custom value for the number of times we should retry a GET request in case of a server error, defaults to 10; server_side_retries_delay allows to customize the time in seconds between the request retries, defaults to 3.

To avoid timeouts with recent versions of firmwares we need to increase the number of server side retries. For example, in idrac firmware series 5.x the time gap between operations is almost 20 seconds instead of the 10 seconds in the 4.x series.

Alters eTag handling in PATCH requests: First, the original eTag is used. In case of a failure, if the eTag provided was weak, it is converted to a strong format by removing the weak prefix. If this approach is not applicable or fails, the final attempt is made omitting the eTag entirely. By taking this approach, no workarounds are applied if BMC is handling eTags as expected and in case of failures, known workarounds are attempted, improving overall resiliency.
