EMC Dell PowerScale Maintenance Exam D-PSC-MN-01 Prüfungsfragen mit Lösungen (Q121-Q126):

121. Frage
A platform engineer is following the drive replacement procedure for a Dell EMC PowerScale Gen 6 node.
One of the steps is the removal of the sled containing the target drive.
What is the maximum time a sled can be removed from its slot before all drives in that sled are SmartFailed automatically?

A. 15 minutes
B. 50 minutes
C. 20 minutes
D. 10 minutes

Antwort: A

Begründung:
When performing drive replacements on a Dell EMC PowerScale Gen 6 node, it's crucial to adhere to specific time constraints to prevent unintended system behaviors.
Maximum Time Before Automatic SmartFail:
* 15 Minutes:If a drive sled is removed from its slot for more than 15 minutes, OneFS will automatically initiate a SmartFail process for all drives in that sled.
* This time limit ensures data integrity by triggering data protection mechanisms if a drive is presumed lost.
Procedure Details:
* Drive Sled Removal:
* Carefully remove the sled containing the target drive.
* Ensure that you have the replacement drive ready to minimize downtime.
* Time Management:
* Keep the sled out of the chassis forno more than 15 minutes.
* Plan the replacement procedure to stay well within this time frame.
* Consequences of Exceeding Time Limit:
* Exceeding 15 minutes causes the system to treat the drives as failed.
* The SmartFail process begins, impacting system performance and prolonging maintenance.
Dell PowerScale References:
* Dell EMC PowerScale Hardware Replacement Guide:
* Section on Drive Replacement Procedures:
* Specifies the 15-minute time limit for drive sled removal.
* Emphasizes the importance of adhering to this limit to prevent unintended SmartFails.
* Best Practices:
* Preparation:
* Have all necessary tools and replacement drives ready before starting.
* Monitoring:
* Use a timer to ensure the sled is reinserted within the allotted time.
* Post-Replacement:
* Verify the new drive is recognized and the cluster health is optimal.

122. Frage
When a platform engineer disconnects and removes the power supply from a Dell EMC PowerScale Gen 6 node, they see an LED on the inside of the compute module.
What does the LED indicate?

A. Visible LED is from the front panel of the node.
B. Platform engineer has exactly two minutes to swap the power supply.
C. Power supply was not removed correctly and the node is shutting down.
D. Pair node is supplying redundant power.

Antwort: D

Begründung:
In Dell EMC PowerScale Gen 6 nodes, such as the ones in the F-series, nodes are deployed in pairs within a chassis, sharing power supplies for redundancy.
Key Points:
* LED Indicator Inside Compute Module:
* When a power supply is removed from one node, an LED inside the compute module may illuminate.
* This LED indicates that the node is still receiving power from its pair node's power supply, ensuring continuous operation.
* Redundant Power Supply:
* PowerScale Gen 6 nodes are designed with redundant power configurations.
* If one power supply fails or is removed, the paired node's power supply provides power to both nodes.
* Safe Removal and Replacement:
* The LED serves as a visual indicator that the node is still powered, and caution should be exercised when handling components.
* There is no immediate shutdown or time limit for replacing the power supply due to the redundancy.
Dell PowerScale References:
* Dell EMC PowerScale Hardware Installation Guide:
* Chapter on Power Supply Replacement:
* Explains the redundant power features and the role of the pairing between nodes.
* Provides instructions on safely removing and replacing power supplies.
* Visual Indicators:
* Details the meaning of LEDs within the compute module.
* Confirms that an illuminated LED in this context indicates redundant power from the pair node.
* Best Practices:
* Always verify the node's power status before performing maintenance.
* Use the proper procedures to remove and replace hardware components to prevent damage.

123. Frage
During the replacement of a failed hard drive, a key FRU, what steps should be followed to ensure proper installation?

A. Confirming the slot and drive compatibility
B. Verifying the drive firmware version matches the cluster
C. Performing a full data backup
D. Ensuring the node is isolated from the network

Antwort: A,B

124. Frage
A platform engineer has connected to a Dell EMC PowerScale F600 node using a serial connection. The session is unresponsive.
What action should the engineer take?

A. Connect to the primary node of the pair
B. Enable the serial port from the front panel menu
C. Configure the cluster before connecting to the node
D. Check the settings of the serial connection

Antwort: D

Begründung:
When connecting to a Dell EMC PowerScale F600 node via a serial connection and the session is unresponsive, the most common issue is incorrect serial connection settings.
Key Points:
* Serial Connection Settings:
* The serial console requires specific settings to communicate properly:
* Baud rate: 115200
* Data bits: 8
* Parity: None
* Stop bits: 1
* Flow control: None
* Incorrect settings will result in an unresponsive or garbled session.
* Troubleshooting Steps:
* Verify that the serial connection parameters match the required settings.
* Ensure that the correct serial port is being used.
* Check the physical connection for loose cables or faulty adapters.
* Other Considerations:
* The serial port on the node does not need to be enabled from the front panel.
* Connecting to the primary node or configuring the cluster is not necessary for serial console access.
Dell PowerScale References:
* Dell EMC PowerScale Hardware Installation Guide:
* Appendix on Console Access:
* Provides the correct serial connection settings for accessing the node console.
* Offers troubleshooting tips for common connection issues.
* Best Practices:
* Use reliable serial communication software (e.g., PuTTY, Tera Term).
* Confirm that the serial cable and any USB-to-serial adapters are functioning properly.

125. Frage
What is a key step when connecting nodes to the data center's power supply during a PowerScale installation?

A. Implementing power redundancy for each node
B. Labeling power cables according to the nodes they supply
C. Using power cables of the shortest possible length to reduce resistance
D. Ensuring each node is connected to a different circuit breaker

Antwort: A
