Hello guys
I would need some advice. When the primocashe was in trial everything was ok and both of my drives had active L-2cashe. Affter I purchased license Now the level-2 cash is stays disabled for "C" even I already set L2 storage according to the guidance but is active only on "D" Why? How to make it active in "C" as well. Both of my partitions are SSD. The windows partition is Samsung evo plu 970 and "D" partition is Samsung 860 QVO if that make any difference. Please advice

You should never be able to create an L2 cache for an SSD drive. Normally it is blocked by PrimoCache. Simply because reading native data from an SSD performs faster than reading it from a cache so an L2 cache would be useless here.

You may still set an L2 partition on an SSD to provide caching for slower HDD drives. But you do not mention them here. Hence if all your drives are SSD you should be happy with using only L1 cache.

If the L2 Storage volume and target volumes are on the same drive, L2 cache on target volumes will be automatically disabled because this won't help target volumes.
PS. As janusz521 said, usually there is no need to use L2 on fast SSDs. L2 cache is designed to use fast drives to speed up slow drives, like SSD -> HDD, Nvme SSD -> HDD or SATA SSD.
