Ubuntu Server 18.04 not detecting SAS drive
1
I have two SAS drives 72GB. One is the system where Ubuntu server is installed on. The other is also connected but I can’t find it on the server. When I plug an HDD into the server, it outputs it as /dev/sdb but not the SAS?
I think my secondary SAS disk is inside /dev/sda/.
Because when I look at the following output, it shows two drive of 74GB.
Disk /dev/sda: 73.5GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:
Number Start End Size File system Name Flags
1 1049kB 2097kB 1049kB bios_grub
2 2097kB 73.4GB 73.4GB ext4
(parted)
Is this usually like this? And if not, could you guys explain to me how most companies do it? For Storage servers.

Is your server running on a standard consumer motherboard with a SATA controller? if so, are you using a SATA to SAS adapater for these hard drives? The SAS hard drives use a different protocol entirely than SATA, so if either of these cases are true, you won't be able to use SAS hard drives with your server unless you get a hardware controller (LSI MegaRAID is an inexpensive option)

Use the F8 key during boot and see if the drives are configured in a RAID 1 or RAID 10, as those two settings would be why you only see 1 drive. It has been a long time since I have worked on a HP DL360G6, but I believe that you can try configuring the drives to individual RAID 0 so that each can be seen separately. You should edit your question and add more detail that could help us help you! Thank you!

Can you edit your question to include the output ofsudo lsblkwith the other drive plugged in?

Check into installing the hpssacli or just the ssacli which I believe that you can get from HPE themselves downloads.linux.hpe.com/sdr/repo/mcp/pool/non-free. When it is installed trying runninghpssacli ctrl all show configorssacli ctrl all show configand give the output. It should show how many physical drives are detected. You might need to also tryhpacuclibut the same rest of the commands.
