Greetings - I need to perform a head swap from an old FAS3000x series to a 6210 and using the same disk shelves. no additional shelves were purchased. What would be the steps required for to perform this? The 6210 would be 8.04 7-mode coming from 7.x on the 3000 series.
Licenses required (this should not be a problem to obtain what i need)
can this be performed non disruptive with data-motion?
High level processes.
I am sure there is more bullet points need to be added. But by all means folks, feel free to enlighten me with your experiences and any gotcha's.
1. There is no specific licenses needed for conversion. FAS62xx comes with own licenses and you are supposed to install them after upgrade. If old system has more (or different set of) licenses, you are supposed to delete those, that are not available for new one.
2. Head swap is always disruptive with 7-Mode.
3. Tough. See below.
As of now there is no real documentation I am aware of dealing with this. Simply booting 8.x on root volume with 7.x may work, but I have not seen official statement of support (if someone can correct me - excellent). The most bullet proof way I can think of is to loan a head supporting both 7G and 8.x and do two consecutive head swaps with Data ONTAP upgrade in between.
The task is simple to perform but non-trivial to plan. If you do not have good experience with NetApp it really makes sense to arrange for professional service to do it.
In the past I have done head swaps from 7.x to 8.x on filers that couldn't support 8.x. We did this by booting from the root volume after the head swap was done, this would upgrade the raid labels on the root volume to compatiable 8.x raid labels. Once that was done, then you would just install 8.x so it would upgrade the root vol, so it matches whats on the flash.
Well, that’s the worst case. There is no documented procedure to directly head swap from FAS3050 to FAS62xx. And I was told that simply booting 8.0 with root volume from 7.3 was known to cause issues.
One possibility is to carve out several unused disks (take spare), install clean 8.x using FAS62xx and then reassign the remaining disks. Then it may be possible to mark old root volume as root and reboot ☺
