Wait for /var/run/hw-management/sysfs_labels_rdy to exist and contain non-zero value before initializing chassis thermals. This prevents accessing sysfs files before hw-management is fully ready. - Add _wait_for_sysfs_labels_ready() with 30s timeout - Poll every 1 second with appropriate logging Signed-off-by: Jianyue Wu <[email protected]>

…UT so that we can get back to back Paladin ports up with Arista-7060X6-16PE-384C-O128S2 (sonic-net#1144) <!-- Please make sure you've read and understood our contributing guidelines: https://github.com/Azure/SONiC/blob/gh-pages/CONTRIBUTING.md failure_prs.log skip_prs.log Make sure all your commits include a signature generated with `git commit -s` ** If this is a bug fix, make sure your description includes "fixes #xxxx", or "closes #xxxx" or "resolves #xxxx" Please provide the following information: --> #### Why I did it Currently when we loaded HWSKU `Arista-7060X6-16PE-384C-O128S2` on two moby devices and connect their Paladin ports back to back, we can't get link up. It may help if we can get these links up and run the tests. ##### Work item tracking - Microsoft ADO **(number only)**: #### How I did it Created a new `FANOUT` HWSKU containing special lanemap and polarity configs so that we can load `Arista-7060X6-16PE-384C-O128S2` on one Moby and `Arista-7060X6-16PE-384C-O128S2-FANOUT` and get Paladin ports up when connecting them back to back with the following setup: ``` Moby1 Moby2 HWSKU: Arista-7060X6-16PE-384C-O128S2 HWSKU: Arista-7060X6-16PE-384C-O128S2-FANOUT #17 <-> #18 #19 <-> #20 #21 <-> #22 #23 <-> #24 #18 <-> #17 #20 <-> #19 #22 <-> #21 #24 <-> #23 ``` #### How to verify it Verified that all the Paladin ports can link up with the above setup. <!-- If PR needs to be backported, then the PR must be tested against the base branch and the earliest backport release branch and provide tested image version on these two branches. For example, if the PR is requested for master, 202211 and 202012, then the requester needs to provide test results on master and 202012. --> #### Which release branch to backport (provide reason below if selected) <!-- - Note we only backport fixes to a release branch, *not* features! - Please also provide a reason for the backporting below. - e.g. - [x] 202006 --> - [ ] 201811 - [ ] 201911 - [ ] 202006 - [ ] 202012 - [ ] 202106 - [ ] 202111 - [ ] 202205 - [ ] 202211 - [ ] 202305 - [x] msft-202412 #### Tested branch (Please provide the tested image version) <!-- - Please provide tested image version - e.g. - [x] 20201231.100 --> - [ ] <!-- image version 1 --> - [ ] <!-- image version 2 --> - [x] msft-202412 #### Description for the changelog <!-- Write a short (one line) summary that describes the changes in this pull request for inclusion in the changelog: --> Created `Arista-7060X6-16PE-384C-O128S2-FANOUT` based on `Arista-7060X6-16PE-384C-O128S2` and only update lanemap and polarity settings in bcm config. <!-- Ensure to add label/tag for the feature raised. example - PR#2174 under sonic-utilities repo. where, Generic Config and Update feature has been labelled as GCU. --> #### Link to config_db schema for YANG module changes <!-- Provide a link to config_db schema for the table for which YANG model is defined Link should point to correct section on https://github.com/Azure/sonic-buildimage/blob/master/src/sonic-yang-models/doc/Configuration.md --> #### A picture of a cute animal (not mandatory but encouraged)

Why I did it
There will be errors, when accessing sysfs files before the hardware management system is fully ready.
How I did it
_wait_for_sysfs_labels_ready()method inChassisclass to wait for the sysfs labels ready indicator fileinitialize_thermals()to call the wait function before creating thermal objectsHow to verify it
