Discuss Dell D-PSC-MN-01 Exam Topic 3 Question 10

A platform engineer is replacing a compute node in a Dell EMC PowerScale Gen 6 cluster.

Which command should they use to power off the node?

AIsi status -q

BIsi status -h

CShutdown -p now

DShutdown -h now

Suggested Answer: C

To safely power off a node in a Dell EMC PowerScale cluster, use the shutdown command with the appropriate options.

Command Details:

shutdown -p now:

shutdown: Initiates a system shutdown.

-p: Powers off the system after shutdown.

now: Executes the command immediately.

Why Other Options Are Incorrect:

Option A (isi status -q): Displays cluster status; doesn't control power.

Option B (isi status -h): Invalid option; isi status doesn't power off nodes.

Option D (shutdown -h now): Halts the system but may not power it off.

Dell PowerScale Reference:

Dell EMC PowerScale OneFS Administration Guide:

Shutting Down Nodes Section:

Recommends using shutdown -p now for powering off nodes.

Safety Precautions:

Advises to notify users and ensure no critical processes are running.

Best Practices:

Verify that the node is not hosting critical services before shutdown.

Inform cluster administrators of maintenance activities.

"Shutdown -h now" is the standard command, right?

Antonio 11 months ago

Wait, are we sure about that? I thought it was "Isi status -q."

Lettie 11 months ago

Definitely "Shutdown -h now," no doubt about it.

Bambi 11 months ago

I think "Shutdown -p now" is the right one!

Tanesha 11 months ago

Pretty sure it's "Shutdown -h now" for powering off.

Ardella 12 months ago

I remember that "isi status" commands are for checking the status, not powering off. So it must be one of the shutdown commands.

Estrella 12 months ago

I'm leaning towards "Shutdown -h now" since it seems to be the standard way to halt a system, but I'm not completely sure.

Truman 12 months ago

I practiced a similar question where we had to check the status of nodes, but I don't recall the exact shutdown command for PowerScale.

I think the command to power off the node is related to shutdown, but I can't remember if it's -p or -h.

Albina 1 year ago

I feel pretty confident about this one. Based on the information provided, the correct answer is C, "Shutdown -p now". The question mentions a Dell EMC PowerScale cluster, so the standard Linux shutdown command should work, and the "-p" option is for a "power off" operation.

Okay, let me think this through. The question is specifically about a Dell EMC PowerScale cluster, so the standard Linux commands might not be the right approach. I'm leaning towards either B, "Isi status -h", or C, "Shutdown -p now". But I'm not 100% sure.

Mozell 1 year ago

I'm a bit unsure about this one. The question mentions a Dell EMC PowerScale cluster, so I'm not sure if the standard Linux shutdown command would apply. Maybe one of the "isi" commands would be more appropriate?

Jamey 1 year ago

Hmm, this seems straightforward. I think the answer is D, "Shutdown -h now". That's the standard command to power off a Linux system, right?

I think Isi status -q might also be a valid command to check the status before powering off the node.

Soledad 2 years ago

But Shutdown -h now is for a hard shutdown, which is necessary for replacing a compute node.

Heike 2 years ago

Hmm, I'm not sure if Isi commands are specific to the Dell EMC PowerScale platform. C) Shutdown -p now seems like a safe bet.

I'm leaning towards D) Shutdown -h now, since it's the standard command for halting the system.

Lenna 2 years ago

I disagree, I believe the correct command is Shutdown -p now.

Jeannetta 2 years ago

C) Shutdown -p now looks like the most straightforward option to power off the node.
