Megaraid configured in BIOS - Storage/Disks/Directory not show disk

[paiser62]

Hello,
I have a server with Megaraid card and 6 disks of 10TB each configured in BIOS-Megaraid in RAID5.
I can see the disk in Storage/Disks, but I can't create a directory. The array is GPT.
Is there some incompatibility with RAID disks in Megaraid?

It seems the graphical interface was not able to see the Array. But I managed to solve using the command line. I needed to install parted:
apt install -y parted
parted /dev/sdb
lsblk
proxmox-backup-manager disk fs create backup1 --disk sdb --filesystem xfs --add-datastore true
Then it worked.
Thank you
