I have recently moved my Unraid setup to using an LSI 9300-16i while also adding 2 SAS drives. All the legacy SATA drives came up and were recognized by Unraid. The 2 new SAS drives are under "Unassigned Disk Devices" but both have their mount button grayed out.

 

I assumed this was because they are likely in 520 instead of 512 format. So I proceeded to run `sg_scan -I` and grabbed the disk id from there. But then running `sg_format --format --size=512 --fmtpinfo=0 -v /dev/sg2` results in `device not ready` so I ran `scsi_ready -vvv /dev/sg2` and got the following:

sg_turs -vvv /dev/sg2
    open /dev/sg2 with flags=0x800
    test unit ready cdb: [00 00 00 00 00 00]
      duration=0 ms
test unit ready:
Descriptor format, current; Sense key: Not Ready
Additional sense: Logical unit not ready, power cycle required
  Descriptor type: Field replaceable unit code: 0x1
  Descriptor type: Vendor specific [0x80]
    00 00 00 00 00 00 00 00 00 00 00 00 00 00
 Raw sense data (in hex), sb_len=28, calculated_len=28
        72 02 04 22 00 00 00 14  03 02 00 01 80 0e 00 00
        00 00 00 00 00 00 00 00  00 00 00 00
device not ready
Completed 1 Test Unit Ready commands with 1 errors

 

Same result for the second drive as well. So then I figured maybe the card needs to be flashed to a newer firmware and set to IT mode so I flashed it to the latest version and then checked in the bios and confirmed both chips on the card are set to IT mode.

 

Now im kinda at a loss on how to proceed. I doubt both drives(new) arrived dead. Thanks for the help

Yep, 520 won't work, as for the error formatting them, see if they have some kind of protection, that's quite common with used SAS drives, and can prevent formatting.
