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

It's cosmetic, so you can ignore. But understand that if you have a power reset or Takeover/Giveback event in the future, the stack ID's will probably go back to using 1 and 2, again. ... View more

1GbE Cluster interconnects are NOT supported, as of ONTAP 8.2. If you can tolerate the single point of failure, you can run only one 10GbE link between the two nodes (switchless) and use the 2nd 10GbE port for front-end connectivity. ... View more

FAS3020 support ended about 4-1/2 years ago.   You might be able to find guides on the Internet - try searching for "FAS3000 series".   We still have the installation and setup guide posted: https://library.netapp.com/ecm/ecm_get_file/ECMM1280261   The ONTAP 7.3 Documentation Roadmap can help you with documentation titles that you might want to find... https://library.netapp.com/ecm/ecm_get_file/ECMM1278403   ONTAP 7.3.7P1 would be the last valid release for you to run.

If you don't already have the FC mezzanine module, I'm not sure where you'll be able to find them - NetApp no longer sells this platform or module.   The marketing part number is X1150A-R6.   You have to pull the PCM canister to install this module.   The ports are by default ready for attachment to DS14 storage shelves (assuming you have the cables).   There is no mixing between the FC-AL and SAS shelves. They are separate storage domains.  ACP is only applicable to the SAS shelves and the e0P ports on the nodes.     ... View more

I would try Option 9 operations, again. (You will need to copy off your data, if you have any on the system)   It's important to run the Option 9 options serially for each partner... 9a node 1, then 9a node 2. 9b node 1, then 9b node 2.   Ref: FAQ: ONTAP Boot Menu Option 9 (Configure Advanced Drive Partitioning)   ...

An easy way to fix the mismatch would be to purchase 2 x IOM6's to swap out with the IOM3's - ONTAP will essentially treat it as a DS4246 (even if the HDD's themselves are 3Gb/s SAS.).   If you don't go that path, it's not really a blanket statement that everything is throttled down to 3Gb/s on the stack.   SAS is a point-to-point protocol. The speed of a connection during its duration will depend on the components in the path of the connection. If the path goes through a IOM3 in the DS4243 shelf or terminates on a 3Gb/s HDD/drive, then the connection for that I/O transaction will run at 3Gb/s. If the path to a 6Gb/s drive only has 6Gb/s components in it, then the transaction is at 6Gb/s.   Let's assume that you have multi-path HA cabling (MPHA) and you put the DS4243 at one end of the 7-shelf stack.   ONTAP will choose the "shortest path" to the HDD/drive. This will mean that 4 of the shelves will be accessed from one end of the stack while the other 3 will be access from the other end of the stack (again, assuming you have properly cabled for multipath HA (MPHA).   So, this means that 4 of the 7 shelves will be able to form SAS connections at 6G/bs speeds 100% of the time.  The other 3 (including the DS4243) will run with 3Gb/s connections if the path goes through the DS4243 first (at the end of the stack).   Having said all that, I doubt you'll see any tangible performance difference, anyway. Even 3Gb/s SAS is 4 x 3Gb/s lanes = 12Gb/s bandwidth for that path to the 3 shelves from each controller's SAS HBA port. ... View more
