hard disks not detected during installation


Jul 20, 2019
I have an hp proliant DL360p Gen8 smart array P420i RAID Controller.
Proxmox detects the logicals disks (raid 1 (2x146Go) and raid5 (3x300Go) .But I would like to use ZFS (which is incompatible with the physical Raid).
When I delete the logical disks, the hard drives are no longer detected by proxmox. How can i do for proxmox to detect them. Thank you !
(disclaimer, my personal last direct contact wit a HP proliant is a bit ago, so just ignore if I#m completely off target)
Normally it's enough (and desired) to put the RAID controller in HBA mode to pass-through the disks directly so that things like ZFS or Ceph work correctly with those disk.
