Do not do it. That shelf is end of support. It won’t work properly on current ONTAP versions

Disk failures are a pain. ONTAP prevents two disks in the same caddy from being in the same raid group. When a disk does fail it has to fail the serving drives in the caddy and you replaced two at a time

Subject: Migration to DS4486 shelf?
 

Hi there

 

Because of space constraints I am planning to move my 3 pcs. DS212C into a DS4486.

But I have a few questions 😊

My existing disks are X318 (8TB NL-SAS), and I think the caddies for the DS4486 are also SAS, so that should technically fit?

 

Does the NetApp see 24 or 48 disks from the DS4486?  Because I plan to reuse existing disks with aggregates on them…

 

I can see the DS4486 use special PN as spare disks because the caddy has two disks installed.  How does NetApp handle the replacement when one disk of the two dies?

I know the healthy disk is also copied to a spare before you can replace the caddy, but do you then replace both disks, or do you just replace the broken disk of the two?

 

I also have plans on replacing the IOM6 modules with IOM12 just as you can in the DS4246 shelfs..  any issues with that?

 

I know this is close if not far beyond what is supported 😉
