Wallaby Series (3.5.0 - 3.7.x) Release Notes


Bug Fixes

  • 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.

  • Add retries on iDRAC error with code SYS518 and message “iDRAC is currently unable to display any information because data sources are unavailable.” for all request types in addition to existing GET methods. This helps to fix a known intermittent issue when deleting set of volumes one after another and iDRAC is reloading after deleting each volume.

  • Fixes ‘Unsupported parameter name @Redfish.OperationApplyTime’ error on iDRAC firmware version or newer when deleting volumes.

  • 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.

  • Correctly handles error code Base.1.5.PropertyMissing when dealing with hardware that requires TransferProtocolType for virtual media operations.

  • Correctly handles errors on a request that is re-tried after refreshing an authentication token.


Bug Fixes

  • Fixes potential cases where exceptions from the underlying requests library may be raised up through sushy, resulting in client applications possibly not understanding that an error has occurred. The sushy ConnectionError exception is now returned upon any exception falling under RequestException from the requests library.

  • Fixes unreliable behavior with ETag interactions with some BMCs as opportunistic use of compressed responses may cause the BMC to change an ETag response to “Weak”, which is to be expected as an ETag represents an absolute byte-by-byte response consistency, and compression cannot reliably honor that contract. Introduction of a client perceiving a “Weak” ETag may not be expected by the server, and the server may reject responses because the ETag is not a “Strong” ETag when we respond or interact with a resource.

    As a result, requests no longer offer oppurtunistic compression of responses as an acceptable possibility, which overall has minimal impact, espescially when compared to the value of consistent BMC behavior and interaction.

  • Fixes an issue in the sushy connector object handling where a Sushy client utilizing basic authentication would not raise an AccessError exception once the credentials stopped working. We now explicitly check to see if basic authentication is in use, and raise the exception if an AccessError is encountered.

  • 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.


Bug Fixes

  • Makes the unstripped version of an Etag available in addition to the stripped one in order to support vendor implementations which require one or the other.


Bug Fixes

  • Changing boot device string for virtual media from “Cd” to “UsbCd” on SuperMicro machines to match their specific naming convention.

  • If available, uses headers with an Etag to set the boot options.

  • Fixes issues with the refresh of Session based authentication where a previous refresh attempt failing could result in a fallback to Basic authentication and would silently fail. The client library now attempts to re-authenticate.

  • Fixes silent failures when a refresh of an authentication Session fails and was unable to be re-established due to an AccessError. Should this occur, now the AccessError exception is explicitly raised as opposed to attempting to fall back to Basic authentication.

  • Fixes issues where the Session and Basic auth interface would fallback to Basic authentication should a ConnectionError exception occur while attempting to perform an authentication action. ConnectionError exceptions are signs of networking transport issues, and should be investigated. A ConnectionError exception is now raised.

  • Prevents the combined Session and Basic authentication support from falling back to Basic authentication once Session based authentication has been established. This should be considered a potential security issue or an environmental change requiring potential client re-initialization. This is exposed as an AccessError exception. Continued operations against the Sushy library will attempt to reauthenticate, if possible.

  • Resolved virtualmedia attach failures caused by the lack of TransferProtocolType parameter in the request payload which is required by certain BMCs (e.g. on Nokia servers). This is done by adding capability to retry virtualmedia InsertMedia with the updated payload in such cases.

  • Fixes incompatibility with BMCs that require use of a specific SettingsObject URI specified in @Redfish.Settings resource in order to set BootSourceOverride or similar attributes. For example, this is required on Nokia servers.


Upgrade Notes

  • “Inserted” and “WriteProtected” optional attributes are no longer present in the InsertMedia API call payload when default values {“Inserted”: True, “WriteProtected”: True} are specified by the consumer (e.g. Ironic) and PATCH method of configuring virtual media is not used. Behaviour is unchanged if PATCH method is used.

Bug Fixes

  • Removing “Inserted” and “WriteProtected” parameters from the Redfish VirtualMedia::insert_media() API call payload when default values {“Inserted”: True, “WriteProtected”: True} are set and PATCH method is not used. Those parameters are optional as per Redfish schema 2021.1. Some BMCs (e.g. SuperMicro X11/X12 platforms) treat these fields as read-only and setting them causes vMedia insert failures. These attributes should default to True on the BMC side. Some BMCs using PATCH method of configuring virtual media (e.g. Lenovo SD530) still require “Inserted” attribute, so only changing this for non-PATCH methods of configuring virtual media such as InsertMedia action.

  • Fixes Processor.sub_processors for “‘Processor’ object has no attribute ‘conn’” error.


Bug Fixes

  • Adds a fallback for inserting and ejecting virtual media using the PATCH HTTP request instead of the explicit action URIs. The fallback is required for Lenovo ThinkSystem machines (i.e. SD530, ..) that only implement the PATCH method.


New Features

  • Adds new method get_task_monitor to retrieve TaskMonitor instance by task monitor URI.

  • Adds support for fetching and resetting individual UEFI secure boot databases.

Deprecation Notes

  • Existing two TaskMonitor-s are deprecated and replaced with one taskmonitor.TaskMonitor.

    For resources.task_monitor.TaskMonitor users changes include:

    • in_progress is replaced with method check_is_processing

    • location_header is replaced with method task_monitor_uri

    • there is no replacement for set_retry_after, taskmonitor.TaskMonitor sets this internally from Retry-After header

    For resources.taskservice.taskmonitor.TaskMonitor users changes include:

    • check_is_processing, sleep_for and static get_task_monitor added.

    • in __init__ parameter field_data is deprecated, use response

    • in __init__ parameter task_monitor is renamed to task_monitor_uri

    • task_monitor is deprecated, use task_monitor_uri

    • retry_after is deprecated, use sleep_for

    Methods create_volume, delete_volume, initialize_volume in volume module are deprecated and replaced with ones named create, delete and initialize. New methods for asynchronous operations return taskmonitor.TaskMonitor instead of deprecated resources.task_monitor.TaskMonitor.

    Method resources.updateservice.UpdateService.get_task_monitor is deprecated, use Sushy.get_task_monitor instead.

Bug Fixes

  • Automatically retries internal server errors from GET requests.
