I don't think there is a stated maximum size to a logical disk you can create if that's what you're asking. There's a claimed limit of 200 physical disks but it's really down to how many you can connect to it using expanders. Assuming 6TB disks that's a tad over 1 PB not that you're likely to have the enclosures to reach 200 disks.

There's probably a limit of just over 9PB due to it having 64 bit internal architecture but HPE don't mention that, probably because they don't have enough money to buy 9PB of disks.

At a guess though you're getting a warning message trying to create a logical disk over 2.2TB because you would either have to enable UEFI instead of BIOS or create more than one logical disk on the array.
