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 license expiration date is within a week, Dell PowerStore generates awarning-level alert. This alert severity level is used to indicate that action should be taken soon to prevent potential service disruptions or limitations on system functionality. A warning alert is not as severe as a major alert, which would indicate immediate attention is required, but it is more critical than an informational alert, which is typically used for general notifications without immediate impact.

The warning alert serves as a proactive reminder to renew or update the license to ensure continuous operation of the PowerStore system.It is important to address these alerts promptly to maintain access to all features and avoid any limitations on system management operations1.

For more information on alert severities and license management in Dell PowerStore, administrators can refer to the PowerStore documentation on License State Alerts and the PowerStore Manager Overview, which provide detailed explanations of the different alert levels and the steps to manage and resolve licensing issues23. Following the guidelines in these documents will help ensure that the storage system remains fully operational and compliant with licensing requirements.

When replacing any components in a Dell EMC PowerStore array, it is critical to have an Electrostatic Discharge (ESD) Kit on hand to avoid equipment failure.

Before beginning any maintenance work on the PowerStore array, it is essential to:

Use the ESD wristband by attaching one end to your wrist and connecting the other end to a grounded object.

Wear ESD gloves to handle sensitive components.

Ensure that the work area is free from static-prone materials and conditions.

Follow the detailed safety precautions and procedures outlined in the PowerStore Installation and Service Guide1.

Using an ESD Kit is a standard safety practice in the maintenance of electronic equipment, as static electricity can cause irreparable damage to sensitive components.The Dell PowerStore Installation and Service Guide provides comprehensive safety instructions, including the use of ESD protection, to ensure the safe handling of replaceable units2.

The Dell EMC PowerStore equipment in the rack requires additional stabilitywhen shipping the system.

When preparing Dell EMC PowerStore equipment for shipping, it is crucial to ensure that the system is stable and secure to prevent any damage during transit.

Additional stability measures might include securing the equipment within the rack using appropriate brackets, using pallets designed for shipping heavy equipment, and ensuring that the rack is properly balanced.

The need for additional stability is not typically associated with environmental conditions such as humidity or temperature but is a standard precaution during the physical movement of the system to safeguard against vibrations, shocks, and impacts that can occur during shipping1.

For intra-cluster management within Dell EMC PowerStore systems, theinternal networkis used. This network is specifically named the Intra-Cluster Management (ICM) and Intra-Cluster Data (ICD) networks.Each node in a PowerStore cluster communicates with other nodes through bonded ports that are part of this internal network12.

The ICM and ICD networks are crucial for the cluster’s operation as they allow for the management and coordination of data across the cluster. In multi-appliance PowerStore clusters, these networks communicate through the top-of-rack switch network with untagged VLAN network packets that have auto-generated IPv6 addresses.For single-appliance clusters, starting in PowerStoreOS 1.0.2, the ICM network communicates through the backplane within the appliance instead of through the top-of-rack switch2.

In summary, the internal network is essential for the functioning of a PowerStore cluster as it facilitates the necessary communication between nodes for management and data operations. This design ensures high availability and efficient management of the storage system.

The protocol used for the storage network in Dell PowerStore systems is Fibre Channel (FC). FC is a high-speed network technology primarily used for storage networking.Dell PowerStore utilizes FC as part of its all-NVMe design, which also includes NVMe-over-fabric networking to deliver low latency performance for storage workloads1.

Fibre Channel provides several benefits for storage networks, including:

High throughput and low latency for storage operations.

Support for long-distance networking, which is beneficial for disaster recovery and remote backups.

A mature and widely supported ecosystem with a variety of hardware and software options.
