Huawei H13-624_V5.5 Exam - Topic 2 Question 20 Discussion

A financial customer purchased an OceanStor Dorado 18000 storage system for basic service deployment. During management, an engineer discovered that the running status of an iSCSI port on DeviceManager was "Link down". After checking the indicator in the equipment room, the engineer discovered that the link indicator of the iSCSI front-end port was steady red. Which of the following are not the possible causes of the exception?
B) The IP address of the iSCSI front-end port is incorrect. and D) The IP address of the service network port on the application server is incorrectly set.
A) The optical module type is incompatible with the host port.
C) The cable between the application server and the storage device is loose.

Show Suggested Answer Hide Answer
Suggested Answer: B, D

Huawei's troubleshooting guidance foriSCSI Link Failurestates that when therunning status of an iSCSI host/front-end port is ''Link down''and thelink indicator is steady red or off, the fault is investigated as aphysical/link-layer problem. Huawei's documented possible causes include items such ascables between the host and storage being removed or damaged,optical module faults/incompatibility, orfront-end port faults.

Therefore,Acan be a possible cause because Huawei has a specific fault case for anincompatible optical module typecausing the port to be unavailable.Ccan also be a possible cause because Huawei explicitly listscables removed or damaged/looseas a cause of the link-down condition.

BandDarenotpossible causes of this specific exception. Incorrect IP settings on either thestorage iSCSI front-end portor theapplication server service network portarenetwork-layer configuration issues, but they donotcause the physical link indicator to turnsteady redor the port running status to becomeLink down. A physical link-down alarm points to hardware, cabling, or optical-module problems instead.

I think all options could be causes except D. It’s unrelated to iSCSI.

I believe A is definitely a cause. Wrong module type can lead to link issues.

I’m not sure about B. The link down is more about physical connection.

I’m leaning towards B being a possible cause. Incorrect IP can disrupt communication.

True, but I think C is also likely. A loose cable can definitely cause link down.

Agreed, D doesn't affect the iSCSI port directly.

I think D is not a cause. It's about the service network, not iSCSI.

I thought the optical module could be a factor, so A might be a cause too.

A loose cable could totally cause that issue, so C is a possible cause.

I wonder if the service network port's IP address being incorrect could actually lead to a "Link down" status; it seems a bit unrelated to the iSCSI port directly.

I practiced a similar question where a loose cable was the culprit, so I think that one could be a possible cause here too.

I remember studying about iSCSI configurations, and I think the IP address settings are crucial for connectivity.
