Checking if the warehouse has the BAM:
1) Log in to YDNA Warehouse and click the Manage button on the test Subject.
2) Find the Big Y test kit data and click the Manage button. ?You will see a screen like this.

3) If you see any file called chrY.bam, chrYM.cram or callable_status.bed, you are good! ?No action is needed. The BAM/CRAM file just might not be re-uploaded yet. If you only see the files pictured above, a BAM file hasn't been submitted.
4) Open your FTDNA account in another browser window and navigate to your Big Y results page.
5)?Click the blue Download Raw Data button. This will open a modal dialog box with a privacy information statement.
6)?Click the green Share button to access a file download URL token.
7)?Copy the token into the "Retrieve file from Cloud service" box. The link will be nearly 500 characters long.
8) Click the Retrieve file button.
The BAMs are typically processed in 72 hours and this page gets some additional tabs with analysis information.
Thanks for the question.
