Xena Series (3.8.0 - 3.12.x) Release Notes¶
3.12.6-5¶
Bug Fixes¶
Fixes bug where sushy would not pass a read/connect timeout through to requests when making requests to a redfish service. This means that an ill-timed failure could cause python processes calling sushy to freeze indefinately.
Fixes ‘Unsupported parameter name @Redfish.OperationApplyTime’ error on iDRAC firmware version 6.00.02.00 or newer when deleting volumes.
Correctly handles errors on a request that is re-tried after refreshing an authentication token.
3.12.6¶
Bug Fixes¶
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.
Correctly handles error code
Base.1.5.PropertyMissing
when dealing with hardware that requiresTransferProtocolType
for virtual media operations.
3.12.5¶
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.
3.12.4¶
Bug Fixes¶
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.
3.12.3¶
Bug Fixes¶
Fixes potential cases where exceptions from the underlying
requests
library may be raised up throughsushy
, resulting in client applications possibly not understanding that an error has occurred. The sushyConnectionError
exception is now returned upon any exception falling underRequestException
from therequests
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 ifbasic
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.
3.12.2¶
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.
3.12.1¶
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 toBasic
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 anAccessError
. Should this occur, now theAccessError
exception is explicitly raised as opposed to attempting to fall back toBasic
authentication.
Fixes issues where the
Session
andBasic
auth interface would fallback toBasic
authentication should aConnectionError
exception occur while attempting to perform an authentication action.ConnectionError
exceptions are signs of networking transport issues, and should be investigated. AConnectionError
exception is now raised.
Prevents the combined
Session
andBasic
authentication support from falling back toBasic
authentication onceSession
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 anAccessError
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.
3.12.0¶
New Features¶
The
VirtualMedia.insert_media
call now supports credentials for theimage
URI.
Bug Fixes¶
Changes the default value of “WriteProtected” parameter in in VirtualMedia::insert_media() from False to True. This is to match Redfish schema 2021.1 and VirtualMedia.v1_3_0: https://redfish.dmtf.org/schemas/v1/VirtualMedia.v1_3_0.json
