Linux command to display the number of hard drive slots your machine has



I'm currently working on a Linux machine and I want to know if there is a command that tells you the number of hard drive slots the actual machine has regardless of whether there are hard drives installed or not. I know reading the machine's manual provides that information but is there any way to get this information by command line?



I've tried lshw and dmidecode commands but they do not provide information on slots. This specific machine has 6 slots for hard drives to be installed with only 3 currently occupied. It does not have hardware raid either so I cannot use megacli.



Any help would be appreciated.





Welcome to Stackoverflow. Please take some time to read the help pages, especially the sections named "What topics can I ask about here?". Your question does not seem to be about programming. Your question could be more appropriate on one of the many stackexchange sites, namely superuser.com

Can’t you use fdisk?

It provides information on installed drives not the actual number of slots the machine has. There are commands where it will provide the slot number associated with the installed hard drive but I want to know if there is a command that can provide information on how many drive slots there are in the machine regardless of if there are hard drives installed or not. In my case, when there are not drives installed.

Stack Overflow is a site for programming and development questions. This question appears to be off-topic because it is not about programming or development. See What topics can I ask about here in the Help Center. Perhaps Super User or Unix & Linux Stack Exchange would be a better place to ask.

lsblk should list all block devices. If you want only physical disks you can use lsblk -d.


lsblk


lsblk -d



Example:


lsblk -o name,serial



Output:


NAME SERIAL
sda S2U5J1VZ500792
├─sda1
└─sda9
sdb W3APDFP8
├─sdb1
└─sdb9





Already tried that as well. It only shows installed drives. I'm looking for a command that tells you the number of hard drive slots the actual machine has regardless of whether there are hard drives installed or not.

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas...

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right. What's parberakan ? What's pokeArr ? – T.J. Crowder Aug 8 at 12...

Creating a leaderboard in HTML/JS

Image
Clash Royale CLAN TAG #URR8PPP Creating a leaderboard in HTML/JS I'm trying to create a top 10 leaderboard, for now, I've only implemented 3 players, but I'm coming across an issue. My script doesn't seem to be outputting anything on webpage. The purpose of the script is to compare 3 arrays, player1,player2,and player3 solely based off of score. Which is the 2nd index of each array. I want the script to list the players in order of highest score. This method doesn't really seem to be efficient, especially when I'll have to add 7 more players. Could someone suggest perhaps an easier approach, as well as show me why my script wont output the info. Here's the JS function leaderboard() { var player1 = name:"Thomas",date:"01/23/18",score:"201"; var player2 = name:"Michael",date:"03/24/17",score:"943"; var player3 = Name:"Lisa",date:"06/04/18",Score:"79"; if(player1[2]...
