Dell EMC Dell PowerStore Maintenance Achievement Exam Practice Test

Answer : A

When observing the base enclosure front view of a Dell PowerStore system, a solid amber drive LED is an indication of afaulted drive.This LED status is used to alert the storage administrator that there is a fault within the drive that requires attention12.

The LED states for the Dell PowerStore base enclosure are as follows:

Blue: Power is on, and no fault has occurred.

Solid Amber: Power is on, and a fault has occurred within the enclosure.

Blue after Amber Alternating: Power is on, but the system is not initialized.

Off: Power is off.

In the event of a solid amber LED, the recommended steps are:

Identify the faulted drive: Look for the drive with the solid amber LED.

Check the PowerStore Manager: Use the PowerStore Manager to identify the specific error or fault code associated with the drive.

Follow the troubleshooting steps: Refer to the Dell PowerStore Troubleshooting Guide for detailed steps on resolving the issue with the faulted drive.

Replace the drive if necessary: If the drive is determined to be faulty and cannot be recovered, follow the Dell PowerStore Hardware Information Guide for instructions on safely replacing the drive.

For more detailed information and guidance, refer to the official Dell PowerStore documentation, such as the PowerStore Hardware Information Guide and the PowerStore Troubleshooting Guide, or contact Dell support directly

Answer : B

The account credentials needed to run diagnostic commands on Dell PowerStore Maintenance are for the service account.

The service account is specifically designed for performing specialized service functions, including running diagnostic commands1.

To run service commands, you would typically:

Enable SSH in PowerStore Manager under Settings.

Use an SSH client to connect to the management IP.

Log in using the username and password for the service account2.

The service account has the necessary permissions to execute service scripts and commands that are used for diagnostics and troubleshooting3.

It is important to note that the service account password should be changed from the default during the initial configuration of the appliance for security purposes1.

For more detailed information on using the service account for diagnostics and other service tasks, refer to the Dell PowerStore Service Scripts Guide or contact Dell Support.

Answer : D

The correct description of the SAS cabling when adding an expansion enclosure to a Dell EMC PowerStore, for each node and expansion enclosure side, is Option D: SAS cabling goes from existing A ports to new B ports. At the last enclosure, SAS cabling returns from the A ports to the alternate node's B ports.

When adding a SAS expansion enclosure to a Dell EMC PowerStore system, the cabling must be done in a specific manner to ensure proper connectivity and performance.

The SAS cabling should start from the existing A ports on the base enclosure and connect to the new B ports on the expansion enclosure1.

At the last expansion enclosure in the chain, the SAS cabling should return from the A ports back to the B ports on the alternate node1.

This cabling method ensures that each node is connected to each expansion enclosure and that the enclosures are daisy-chained correctly for optimal performance and redundancy1.

For detailed cabling instructions and diagrams, it is recommended to consult the Dell PowerStore Installation and Service Guide or contact Dell EMC support for assistance.

Answer : A

The correct procedure for a Storage Administrator to add a new PowerStore 9000T appliance into an existing single appliance Dell EMC PowerStore 3000T cluster is to add the new 9000T appliance into the cluster per the procedure; mixed models of the same type are supported.

Dell PowerStore allows for the addition of appliances to an existing cluster, enabling both scaling up and scaling out.

When adding a new appliance to an existing cluster, it is important to ensure that the appliance is uninitialized and that both the new appliance and the existing cluster are in a healthy state1.

The process of adding an appliance is facilitated through the PowerStore Manager. The administrator should navigate to the Hardware page and click the Add button to present the available unconfigured appliances that can be added1.

It is not necessary to configure additional VLT links on the ToR switching specifically for the 9000T to support the increased inter-switch network load as part of the initial addition process1.

There is no requirement that the appliance model and type must match when clustering appliances together, allowing for mixed models of the same type within a cluster1.

Removing NVMe NVRAM drives from the 9000T is not a standard procedure for clustering and is not required for the caching configuration of all clustered appliances to match1.

For detailed procedures on adding appliances to a Dell EMC PowerStore cluster, it is recommended to refer to the official Dell PowerStore Clustering and High Availability documentation or contact Dell EMC support for guidance.

Answer : B

The output of the command ''svc_diag list -- basic'' on a Dell PowerStore system typically shows service tag information.

The ''svc_diag'' command is part of the service scripts provided by Dell for diagnostic purposes on PowerStore systems.

The ''list'' option with the ''--basic'' flag is used to display a list of basic system information, which usually includes the service tag, among other details.

The service tag is a unique identifier for Dell products that is used for various purposes, including support and maintenance.

While the exact output of the command can vary based on the software version and specific system configuration, the service tag is a common piece of information displayed by such diagnostic commands1.

For the most accurate and up-to-date information about the ''svc_diag list -- basic'' command and its output, it is recommended to consult the Dell PowerStore Service Scripts Guide or contact Dell Support directly.

Answer : A

When two fans in a Dell EMC PowerStore system are faulted, the system's behavior is to send an increased fan speed signal to the surviving fans to compensate for the loss and continue normal operations. This is a part of the system's design to ensure redundancy and maintain cooling within operational parameters even when one or more fans are not functioning1.

The system monitors the health of all fans continuously. If a fan fault is detected, the system will:

Generate an alert to notify the administrator of the fault.

Increase the speed of the remaining fans to prevent overheating.

Continue to operate normally unless the temperature exceeds safe operating limits.

The administrator should then take the following steps:

Acknowledge the alert in the PowerStore Manager.

Plan for the replacement of the faulted fans as soon as possible to restore full redundancy.

Follow the replacement procedures as outlined in the Dell PowerStore Installation and Service Guide2.

It is important to address fan faults promptly to ensure the long-term health and performance of the PowerStore system. The increased fan speed is a temporary measure to maintain operations until the faulted fans can be replaced.

Answer : D
