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 run1. 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 steps1.

When the node B embedded module fault LED on a Dell EMC PowerStore system is blinking blue and amber alternating at one-second intervals, it indicates that the node is in service mode1. Service mode is a state where the node is not in normal operation and may be undergoing maintenance or diagnostics.

In service mode, the node is typically isolated from normal storage operations to allow for troubleshooting, hardware replacement, or software updates without affecting the rest of the system. The alternating blue and amber LED is a visual indicator used by technicians to identify the current state of the node.

To return the node to normal operation, the service task must be completed, and the node must be taken out of service mode using the appropriate commands through the system's management interface. For detailed procedures on managing nodes in service mode, refer to the Dell EMC PowerStore Service Manual or contact Dell EMC Support for guidance2.

When the node A and B embedded module fault LEDs on a Dell EMC PowerStore system are alternating between blue and amber, with the blue LED illuminated for 3 seconds, it indicates that the system is not initialized1. This LED behavior is part of the system's design to communicate its current state to the user or technician on-site.

The initialization process is a critical step during the installation of a PowerStore system. It involves setting up the system's configuration, including network settings, storage pools, and other essential parameters. Until this process is completed, the system cannot perform storage operations or host any virtual machines.

To resolve this and initialize the system, the following steps should be taken:

Connect to the system through the PowerStore Manager using a supported web browser.

Complete the Initial Configuration Wizard (ICW), which guides you through the necessary steps to initialize the system.

Once the ICW is completed, the system will finalize its configuration and the LEDs should reflect a normal operational state.

For more detailed guidance on the initialization process and understanding the LED indicators, refer to the Dell PowerStore Installation and Service Guide2. This document provides comprehensive instructions on installing and configuring the PowerStore system, ensuring it is ready for use.

The reason for the best practice of leaving 2 Us of space at the bottom of the rack when racking Dell EMC PowerStore systems is to leave room for serviceability.

When installing a Dell EMC PowerStore system, it is recommended to leave 2 Us of space at the bottom of the rack.

This space is not for cooling, wheel clearance, or stability, but rather to ensure that there is enough room for service activities1.

Serviceability involves the ability to access and maintain hardware components easily. The additional space allows for better maneuverability and access to the system for maintenance and repairs.

Following this best practice helps in preventing potential issues that might arise from cramped spaces, which can make it difficult to perform necessary service tasks1.

For more detailed information on installation best practices, refer to the Dell EMC PowerStore Quick Start Guide or the Best Practices Guide21.
