hello Balazs,
Since this was asked on the Storage Management and Reporting, in both Spectrum Insights / Spectrum Control we do have a possibility to see the tier distribution on the volume level :
So after the vdisk change is done, this has to be showing up properly in the tier distribution column, hopefully this can help. You will also find valuable performance data information.

create your volume on tiered pool and use "chvdisk -easytier off vdiskid" for both vdisk copies.
This command will disable easytier only for this volume copies and will not use ssd's.

Good Day!
I have a very specific question that someone here maybe knows the answer for.
I have to create a 6TB hyperswap volume that will be used for storing logs on a server. The logs itself are important and have to be available even if some of the storage controllers become unavailable, hence the hyperswap. However they do not need to use flash capacity. Nearline SAS is perfectly fine.
The system is a V9000 cluster with 4 AC3 nodes spread between site A and site B. There are 6 storage pools configured 4 full flash and 2 tierd pool with some flash added to the nearline SAS mdisks.
My question is. Is it possible to create the 6TB hyperswap volume in a way that it sits in the tiered pools and only on the Nearline SAS mdisks? No easy tier needed for this specific volume even if the data gets hot.
I tried to create it with mkvdisk but that command does not support hyperswap features. mkvolume does but you can't specify tiers in that command.
Thank you for the answers in advance!
