I have a dell R820 with an LSI 9211-8i HBA installed. I connected one hard drive, a dell with model number HUC101890CSS204, and installed ubuntu 18.04 onto it from a usb stick.
I then added 3 HGST hard drives, model number HUC109090CSS600. All 4 hard drives are connected to the computer via the HBA.
According to this pdf, the HGST drives should be compatible with the HBA.
However, while the HBA can detect all four drives from within its BIOS, and some terminal commands can detect all four drives, I can only mount and access the dell drive.
Output from lsblk (sda2 is the dell drive):

I'm pretty new to this sort of thing, so I'm at a loss. What diagnostics/tools are necessary to access the three additional hard drives?
Thanks.
dmesgoutput for these drives.dmesgfor the different drive names, I found errors that the drives had 520-byte byte sectors, which is the source of the issue. I didn't think to check that since according to the PDF I linked above, these drives should be 512 bytes.lsscsi. See here for further information.sudo mount /dev/sdb1 /media/newhd
