Transition from supportfiles.sun.com to transport.oracle.com
Oracle is moving from the use of supportfiles.sun.com to uploaded support data to and now will be using transport.oracle.com.
Some of the appliances when trying to upload a supportbundle will fail if the code is not at a certain level.
Oracle have released a supportbundle upload mechanism change into Appliance Firmware Releases 2011.1.9.0 and 2013.1.1.6, which transitions the 7000 and ZS3 support file bundle upload from supportfiles.sun.com to transport.oracle.com.
Please read:
Oracle ZFS Storage Appliance: How to Transition from supportfiles.sun.com to transport.oracle.com (Doc ID 1666925.1)
There is also a helpful document that goes step by step though the upload process.
