RAID drive not detected


New Member
Hi All,

I'm trying to make RAID card DELL H740p, with a single NVMe onboard to work on the RHEL 7.3. Understand that the card driver is not preinstall and had installed the driver rpm downloaded from DELL. The OS looks like able to the detect the RAID controller on command modinfo megaraid_sas

But when i tried to lsblk the system did not show any nvme drive (2TB). On controller i tried to change it to HBA mode RAID mode to create a virtual disk to connect, unfortunately both method failed.

Anyone can advise what might be the cause?

[[email protected] ~]# lsblk
sda 8:0 0 447.1G 0 disk
├─sda1 8:1 0 1M 0 part
├─sda2 8:2 0 500M 0 part /boot
├─sda3 8:3 0 4G 0 part [SWAP]
├─sda4 8:4 0 1K 0 part
├─sda5 8:5 0 100M 0 part /boot/efi

sdb 8:16 0 39.3M 0 disk
└─sdb1 8:17 0 39.2M 0 part
