Which component is an FRU?

  1. DIMMs
  2. Embedded IO Module
  3. Nodes
  4. Battery Backup Unit

Answer(s): D

Explanation:

A Field Replaceable Unit (FRU) is a component that can be replaced by the user or technician without having to send the entire product or system to a repair facility. Dell's Customer Replaceable Unit (CRU) program allows customers to replace designated hardware components, which are typically considered as FRUs.
In the context of Dell PowerStore Maintenance, the Battery Backup Unit (BBU) is considered an FRU because it is designed to be easily replaced in the field. The BBU is critical for maintaining power to the system in the event of a power failure, ensuring that data is not lost and the system can be shut down gracefully.

The other components listed, such as DIMMs, Embedded IO Modules, and Nodes, may not be as easily replaceable by the customer or may require more technical expertise or special tools. Therefore, they are not typically classified as FRUs within the Dell PowerStore ecosystem. For detailed procedures on replacing the BBU or any other FRU components, it is recommended to refer to the official Dell PowerStore Maintenance documents and follow the guidelines provided for safe and effective replacement. This ensures that the system integrity is maintained and any warranty or support agreements remain valid.



How many fan module failures can a node tolerate?

  1. 1
  2. 3
  3. 0
  4. 2

Answer(s): A

Explanation:

A Dell EMC PowerStore node can tolerate one fan module failure. The system is designed with redundancy to ensure that if a single fan module fails, the remaining fan modules can compensate for the loss and maintain proper cooling to prevent overheating. The system will increase the speed of the remaining fans to ensure continued cooling.
When a fan module failure occurs, the system will generate an alert to notify the administrator of the fault. The administrator should then take the following steps:
Acknowledge the alert in the PowerStore Manager.
Plan for the replacement of the faulted fan module as soon as possible to restore full redundancy. Follow the replacement procedures as outlined in the Dell PowerStore Installation and Service Guide.
It is important to address fan module failures 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 fan module can be replaced.

  1. See Explanation section for answer.

Answer(s): A

Explanation:



A Storage Administrator ran a PSTCLI command on a Linux host. The error " -bash: pstcli: command not found" appears. How is the problem resolved?

  1. Add /opt/dellemc/pstcli/bin/ in PSTCLI.sh
  2. Run rpm -ihv pstcli to reinstall the PSTCLI software on the Linux host
  3. Install in default directory /opt/dellemc/pstcli-version/bin/
  4. Add the installation directory to the PATH variable on shell initialization file

Answer(s): D

Explanation:

When the error "-bash: pstcli: command not found" appears after running a PSTCLI command on a Linux host, it typically means that the shell cannot locate the pstcli executable in the directories listed in the PATH environment variable. To resolve this issue, the installation directory of pstcli needs to be added to the PATH variable. This can be done by editing the shell initialization file (such as .bashrc or .bash_profile for Bash shell) and appending the installation directory to the PATH variable.
Here are the steps to resolve the problem:
Locate the installation directory of PSTCLI. If you followed the default installation, it should be in /opt/dellemc/pstcli-version/bin/.
Open the shell initialization file in a text editor. For example, if using Bash, you might edit ~/.bashrc or ~/.bash_profile.
Add the following line to the file: export PATH=$PATH:/opt/dellemc/pstcli-version/bin/. Replace /opt/dellemc/pstcli-version/bin/ with the actual installation directory if it is different. Save the file and reload the shell configuration by running source ~/.bashrc or source ~/.bash_profile, or simply close and reopen the terminal.

Verify that pstcli can be found by running echo $PATH and ensuring the directory is listed. Try running the pstcli command again to confirm that the issue is resolved. By adding the PSTCLI installation directory to the PATH variable, the shell will be able to locate the pstcli executable when the command is run. It is important to ensure that the PATH variable is correctly set to include all necessary directories for command-line tools to function properly. If the issue persists, it may be necessary to check the installation of PSTCLI or consult the Dell EMC PowerStore documentation for further troubleshooting steps.

What is indicated when the circled LED on the base enclosure is illuminated amber?

  1. Base enclosure power-on
  2. Cluster discovery state
  3. Base enclosure fault
  4. Cluster service mode

Answer(s): C

Explanation:

When the circled LED on the base enclosure of a Dell PowerStore system is illuminated amber, it typically indicates a fault within the base enclosure. This could be related to various issues such as power supply problems, cooling system malfunctions, or other operational faults that may affect the enclosure's performance.
In Dell PowerStore systems, LED indicators are used to communicate the status of the system's hardware components. An amber LED specifically suggests that there is a problem that needs to be addressed. The steps to investigate and resolve the issue usually include:
Checking the PowerStore Manager for alerts or messages that provide more details about the fault. Inspecting the physical hardware to identify any visible signs of damage or failure. Consulting the Dell PowerStore Hardware Guide for information on LED indicators and their meanings.
Following the recommended actions provided in the guide, which may include checking power connections, ensuring proper airflow, or other hardware checks. If necessary, contacting Dell Support for further assistance, providing them with the details of the fault LED and any other relevant information observed. It's important to address any faults indicated by an amber LED promptly to maintain the integrity and reliability of the storage system. The Dell PowerStore documentation provides comprehensive information on LED indicators and troubleshooting steps to help resolve such issues effectively.
