The server is a dellemc
The raidcontroler in the macihne is a PERC H740P Mini

Welcome to the forums.

You need to get rid of the RAID controller. Hardware RAID controllers are not supported, and ZFS is going to be your RAID controller.

You must pull the H740P and replace it with an HBA. It is not sufficient to switch the H740P to "HBA mode" which is just a lobotomized RAID0 mode. See

What's all the noise about HBAs, and why can't I use a RAID controller?

1) An HBA is a Host Bus Adapter. This is a controller that allows SAS and SATA devices to be attached to, and communicate directly with, a server. RAID controllers typically aggregate several disks into a Virtual Disk abstraction of some sort...

On that Dell You will want to check the technical specifications for what SAS HBA's are supported in your box. But if you're currently running an H740p that's probably the 14th Gen Server so you could probably go with a Dell HBA330. Depending on how it was configured you may need to swap cables out also. Example https://www.dell.com/support/manual...5c7318-b18d-4d5a-9a57-03e580cbb443&lang=en-us Internal: HBA330 (non-RAID) or HBA350i (non-RAID)
