Discuss Huawei H13-624_V5.5 Exam Topic 3 Question 22

Routine management on Huawei flash storage systems involves power-on and power-off. Which of the following statements is false about power-on and power-off?

ABefore powering on the storage system, you need to ensure that all expansion cables are correctly connected. The storage system may work improperly if the connection mode of expansion cables is adjusted after the storage system is powered on.

BIf none of the controller enclosures in the cluster are powered on, you can log in to the BMC system using the external management IP address of the BMC and run the power-on command to power on all the controller enclosures.

CTo power on the storage system after an emergency power-off, you need to press the power button on the controller enclosure.

DFor Huawei OceanStor Dorado 8000 storage, after a controller enclosure is powered on, its cascaded disk enclosures will be automatically powered on.

Suggested Answer: C

The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* covers power management:

- Option A: True. ''Correct expansion cable connections are required before power-on to ensure proper operation.''

- Option B: True. ''The BMC system allows powering on controller enclosures via the external management IP when none are powered on.''

- Option C: False. ''After an emergency power-off, the storage system is powered on via DeviceManager, CLI, or BMC, not by pressing the controller enclosure's power button, which is used for normal power-on.''

- Option D: True. ''In OceanStor Dorado 8000, powering on a controller enclosure automatically powers on cascaded disk enclosures.''

Thus, option C is false.

I think option D is false. The disk enclosures don’t always power on automatically.

True, but what if the button malfunctions?

But C seems straightforward. Just press the button, right?

I feel like option C could be misleading too.

Kimbery 1 month ago

I agree with Gail. It’s risky to assume that.

Gail 2 months ago

Because not all systems power on automatically.

Really? Why do you think that?

Gail 2 months ago

I think option D is false.

I think D is a bit misleading, not all models behave the same.

A is definitely true, gotta check those cables first!

Colton 3 months ago

D seems a bit off; I thought not all systems automatically power on their disk enclosures after the controller is powered up.

Lavera 3 months ago

C sounds right; I practiced scenarios where you had to manually press the power button after an emergency.

Gerardo 3 months ago

I’m not entirely sure about B; I think you can log in to the BMC, but I’m not confident about the power-on command for all enclosures.

Lorean 4 months ago

I remember studying the importance of checking connections before powering on, so A seems true to me.
