@eladgotfrid1 wrote: Coming from 7-mode I have some hard time grasping the cluster mode concepts. If I have 2 shelves and a FAS80xx switchless HA pair, am I better off dividing the disks between 2 aggregates between the two nodes to take advantage of both nodes? Or does it not matter anymore with cdot?   That did not change. Aggregate belongs to a node and all IO to volumes on aggregate is served by a single node. To utilize both nodes you need two aggregates.   The primary difference is that single "vFiler" (which is called SVM here) may contain volumes from different aggregates/nodes and transparently present them via the same LIF. But this incurs overhead of redirecting requests over internal cluster interconnect if LIF is not on aggregate owner.   So there is not much difference in planning, really. Coming from 7-Mode you will probably feel more at home with two SVM each owning resources on one node. ... View more

@storageguy wrote: Can I just shutdown node c and node d with their disk shelfs while node a and node b running with shelfs 00-04?      Yes and now. To be fully functional cluster needs quorum - more than half of nodes. If you lose exactly half of all nodes, remaining nodes will retain quorum thanks to epsilon. But  when you power on half of the nodes on another location, they will not be usable until quorum is attained, so no access to data on these nodes will be possible. So at the end you gain nothing.   So yes, you can shut down one HA pair. No, you cannot bring this HA pair up on another location separately. ... View more

You cannot upgrade from 7-Mode to C-Mode. It is complete new installation and what was present on this system does not matter. You may consider updating BIOS/firmware to the latest version before installing C-Mode though, using 7-Mode. I have seen cases when ONTAP failed to boot on too old firmware. ... View more

@ttran wrote: For most scenarios, the aggregate, volume, and snapshot structure will remain intact when moving the old shelves to the new controllers.   That is true only for moving aggregates between 7-Mode systems (unless something has changed very recently) and there is no information what OP has. It is quite unlikely that any new system today will be (or even supports) 7-Mode. ... View more

I vaguely remember similar problem I had during ARL head swap. Old and new head had different Ethernet ports, and after head swap new node inherits configuration of old head so it had no working cluster ports. I had to manually adjust configuration before node could join the cluster, but I do not remember how.   For next head swap with this customer I configured cluster ports in advance to ensure there was some overlap so at least one working cluster port was available after head swap. ...

The least disruptive is to add AFF220 to the cluster, move data off FAS2554 and remove it from cluster. This can be done completely online. Other options depend on licenses you have, how much downtime can you afford, your skills etc. It is really beyond simple forum question, it is more a project work. ... View more

@SpindleNinja wrote: from the 12GbSAS deck - A maximum of one transition from 12Gbps to 6Gbps modules is supported It is a bit unclear whether embedded IOM (IOM12E) is counted here (it says "external stack" about entry systems). Also it seems the primary use case for lifting this restriction is extending existing IOM6 stacks by IOM12 shelves. So I am not sure if even IOM12E - IOM12 - IOM6 - IOM6 would be valid ("IOM6 CIRCLE ports must be used for connection to IOM12 ports" and when going from IOM12 to IOM6 we connect IOM6 with SQUARE port ...).   So it amounts to - is IOM12E - IOM6 speed transition or simply (IOM6) stack attachment? ...
