The cleanest way would be to "restransmit" the AutoSupport you want (you need its sequence number) to a local .7z file - then using the SPI web interface (HTTPS) to copy it to a jump host.

Sure... you can initialize a single-node system with ADP-eligible systems. When initializing a system pre-9.2 with an ADP-eligible system, you always want to start initialization on node A first - once disks are zeroing, then you can start the init on Node B.   But if you are dealing with an HA pair, you need to initialize them "holistically".  Here's a KB that shows you how you'd go about converting/re-initing pre-9.2. How to convert or initialize a system for Root-Data-Data Partitioning   With Boot menu option 9, a 9a + 9b will completely intialize a system with ADP, if eligible and sufficient disks are available.

Note: The last supported ONTAP release for IOM3-based shelves is 9.3, actually. 9.3P11 is a good one...   The short answer is "no".  Root-data partitioning is a HA-scoped operation. Both nodes in the HA pair need to be initialized at the same time. So ARL-type operations won't help, here.   If you figure a way to move your data/volumes (e.g. swing gear) somewhere else, you can reinitialize the system with the IOM12 shelves using boot menu 9 (root data partioning operations), available with ONTAP 9.2 and later. ...

DO NOT modify to non-ha in maintenance mode. You are running a 2-in-1 chassis HA pair and that is the mode you should stay in.   Looks like "storage failover" HA is not happy. Try toggling it (disable/enable). It should automatically set "cluster ha" to true. If not, try to enable it manually, again.   Worst case, halt both nodes and verify disk ownership is as expected from maintenance mode.   Better yet, open a case with NetApp Support. ... View more
