How to know I have raid or hardware raid?

Without asking the provider is there any way I can ssh and get information if I have Raid set up and if it is a hardware raid ?

Who's the server with? It will normally tell you on the pricing. If it doesn't say Hardware raid it normally means it's just software.
You can run this
cat /proc/mdstat
and see what it says.smartctl -a /dev/sda
is a good one. It won't return drive details through a hardware RAID controller until you add a-d
+arg to it.Also,
lspci
will show you what controller cards are in the system, which can be matched up tolsscsi
drives.That's definitive...in fact, I don't think mdadm even has a list command - they just tell you to look at mdstat.
@Oldmanasking, if you see something like this, it's software raid:
If you don't see any mdXX devices, it's not.
As above if you don't see any in mdstat..
Request for IPMI and dig details what kind of HW Raid you have configured. You should understand the arrays configured.
Depending on the controller there's likely a command line utility. For example, lspci tells me the following:
There's a utility called lsiutil for LSI raid cards:
Also, why don't code tags work properly? The ticks don't work either. What's the correct way to post code on this forum?Got it. Use pre tags, not code.www.internetbrothers.co.kr and they tell me they have assigned a hardware raid I just want to know by myself
What service are you using? VPS or Dedicated Server?
If it's a VPS, you can't know whether they're using RAID or not.

This is about my dedicated server .
So follow the several valid options others have provided above.
