FAS 3170 aggr issue

Mark Flint
Hi all. I have 2 x FAS3170’s, both now running 8.0.5P1. On one unit, I can build an aggregate of over 70TB, 
yet on the other, it won’t allow this to happen. Both aggr’s were built using the CLI :-

aggr create aggrgate1 –B 64 –r 16 –t raid_dp 112 ( 96 )

the 96 is the aggr built on the unit that is restricting aggr size. 

Anybody seen this before, or have any ideas?

Thanks,

`Mark

Honestly, I'm a little more interested in the controller that let you build an aggr over 70TB.  According to the HWU, the max aggr size for a FAS3170 running 8.0.5 is 70TB. 

Maybe this is a dumb question, but are you sure they are both running 8.0.5P1?  It looks like the max aggr size was increased in 8.1, and then again in 8.2.

Re: FAS 3170 aggr issue

No, I’ve discovered a little more info. It seems that the units have different disks, and they format to different sizes.
This translates to being able to build a 112 disk aggregate on one unit, but not the other, due to the difference
in the formatted size (I think, yet to confirm by doing the maths manually). So, I _do_not_ have an aggregate over 
the 70TB size limit, I just have different operable disk sizes. 
I’m actually quite relieved by this discovery, as for a short while, I thought I’d managed to get a 3170 outside of
it’s normal operating parameters, but it turns out not :)  I’m just not that good at maths.
