Installing TrueNas on Dell R740xd with a Dell HBA350i Adp

[sakyamuni13]

Hello,

I am beginner, and trying to install TrueNas on a R740xd with a Dell HBA350i Adp.

The install goes well (on 2 ssd 480Go) but when I have to reboot and remove the usb key, it tells me that it can't find the drive.

Here is my spec :
2 x 480 Go SSD SATA (for system TrueNas)
2 x 300 Go SAS 15k (for cache)
12 x 8 To Nearline SAS 7200 (for raid zfs data)
Idrac 9

Thank you for your advice.
