The pureadm command suite is the primary CLI tool used by Implementation Engineers and Support to manage the Purity operating environment's services and high-availability states. After a controller reboot-whether part of a hardware replacement, NDU, or fresh install-it is critical to verify that the Purity software stack has initialized correctly and that all sub-services (such as the I/O handling process, management daemon, and scut) are running.
The specific command pureadm list is the correct syntax to display a summary of the Purity services and their current status (e.g., running, stable, or stopped) on the local controller. This command provides a clean, immediate view of the service stack's health. If the output shows all expected services as "running," the engineer can confirm the controller has successfully rejoined the cluster and is ready to handle operations.
While pureadm alone might print help text and pureadm status is often a valid guess for other systems, the strict syntax for FlashArray implementation verification relies on pureadm list. This step is a standard part of the "Health Check" procedures found in upgrade guides. Failing to verify service status before proceeding (e.g., failing over to the other controller) could lead to an outage if the rebooted controller hasn't actually fully started its data services. Therefore, pureadm list is the validation checkpoint before declaring the controller healthy.
