To view the status of only Portworx pods within the “portworx” namespace, administrators should use label selectors with kubectl. The command kubectl -n portworx get pods -l name=portworx filters pods by the label name=portworx, showing only pods related to the Portworx deployment. This is more precise than simply listing all pods with -o wide, which includes unrelated pods. Checking Portworx pods’ status is crucial for monitoring cluster health, identifying pod restarts, or troubleshooting failures. The Portworx installation manifests and documentation specify labels applied to Portworx pods, enabling operators to filter efficiently. Using this command supports focused operational monitoring and streamlined debugging within Kubernetes environments running Portworx【Pure Storage Portworx Kubernetes Guide†source】.

Stork version 2.3 is the minimum version required to support Application Backup features in Portworx. Application Backup allows for consistent snapshots and restores of complex, multi-volume, and multi-pod stateful applications. This capability depends on enhancements introduced in Stork 2.3 that enable application-aware backup orchestration, coordination between Kubernetes and storage layers, and integration with backup policies. Earlier Stork versions lack these features, making them unsuitable for application-level backups. Portworx release notes and Stork documentation confirm that version 2.3 introduced key functionalities that underpin the reliable backup and restore workflows for stateful workloads, making it a baseline requirement for disaster recovery and business continuity implementations involving application backups【Pure Storage Portworx Backup Docs†source】.

When security is enabled in Portworx, all commands, including those issued via the pxctl CLI, require authentication to access the cluster. If pxctl returns an “access denied” error, it means the CLI does not have valid credentials. To regain access, administrators must provide authentication details using the --user and --password flags or configure a context with an authentication token. The username and password are stored securely within the Kubernetes secret px-admin-token. Using these credentials ensures pxctl commands are authorized to perform management operations. Without authentication, Portworx enforces strict access controls to protect sensitive storage operations and data. While creating new contexts via pxctl context create is a valid method, initially supplying credentials is mandatory. Failure to authenticate prevents any management activity, reinforcing Portworx’s security posture. Official security guides outline these steps as fundamental to transitioning from unsecured to secured cluster operation and managing authenticated access effectively【Pure Storage Portworx Security Guide†source】.

An Autopilot rule in Portworx consists of four main parts: Selector, Namespace Selector, Conditions, and Actions. The Selector defines the set of volumes or pods the rule applies to, often using labels. Namespace Selector further narrows the scope to specific Kubernetes namespaces, allowing targeted policy application. Conditions specify triggers or thresholds such as capacity utilization, I/O metrics, or time-based schedules. When conditions are met, the Actions section defines automated responses such as volume expansion, migration, or alerting. This modular rule design enables flexible, policy-driven automation for storage management, helping maintain cluster health and performance without manual intervention. The Portworx Autopilot documentation provides detailed schema and examples, emphasizing these components as foundational for dynamic, autonomous cluster operation【Pure Storage Portworx Autopilot Guide†source】.

To view current alerts raised by Portworx within the cluster, the primary command is pxctl alerts show. This CLI command lists all active alerts with details such as severity, affected resources, and timestamps. It helps administrators quickly identify issues impacting cluster health, storage pools, volumes, or nodes. While Grafana is a powerful visualization tool often used alongside Prometheus for monitoring, it requires additional setup and does not directly replace the immediate, real-time alert query functionality of pxctl. The pxctl cd list alerts is not a valid command. Portworx documentation emphasizes pxctl alerts show as the go-to tool for alert inspection during operational checks and troubleshooting, offering a concise and focused alert view integrated with Portworx’s internal alerting system【Pure Storage Portworx Alerting Guide†source】.
