The command pxctl cluster status provides a concise summary of the Portworx cluster's health and operational status. This includes node states, storage pool information, volume statuses, and quorum information. It is the primary CLI command for administrators to quickly assess cluster health and detect any issues affecting storage availability or performance. helm list --px is a Helm package management command unrelated to cluster status, and kubectl get pxstatus is not a valid Kubernetes or Portworx command. Portworx documentation recommends pxctl cluster status as an essential monitoring command during routine operations and troubleshooting to ensure the cluster is functioning properly and that all nodes are communicating and healthy【Pure Storage Portworx CLI Guide source】

When using Portworx Asynchronous Disaster Recovery (DR) to migrate workloads and storage across clusters, network policies can sometimes interfere with seamless failover. The label skipNetworkPolicyCheck: true can be used to instruct the DR mechanism to bypass strict network policy checks during migration. This allows applications and volumes to migrate even if network policies differ or are incompatible between source and destination clusters. Without this label, migration might be blocked or fail due to network restrictions. By default, network policies are not always migrated, and strict checks are performed unless explicitly skipped. Portworx DR documentation details this option as a means to increase migration flexibility, reduce operational friction, and enable faster recovery during disaster scenarios while administrators work on aligning network configurations【Pure Storage Portworx DR Guide source】.

To check Portworx-specific alerts on a healthy node, administrators use the command pxctl alerts show. This command displays current alerts raised by Portworx, including warnings and critical notifications about storage, nodes, and cluster health. Even if one node is down, alerts from the healthy nodes can provide insights into cluster-wide issues or the status of the affected node. While journalctl displays system and service logs and kubectl describe node shows Kubernetes node info, neither provides aggregated Portworx alert data. The Portworx observability documentation recommends using pxctl alerts show for focused monitoring and alert management, enabling administrators to respond effectively to operational events within the Portworx cluster【Pure Storage Portworx Monitoring Guide source】.

In Portworx, managing credentials for cloud object stores is vital to enable features like cloud snapshots and backups. The command pxctl credentials create is used to create and register cloud credentials with the Portworx cluster. This command allows administrators to specify provider details such as AWS, Google Cloud, or Azure, and input necessary access keys, secret keys, regions, and endpoints. Proper credential configuration enables Portworx to authenticate with external object stores securely, ensuring reliable data movement and disaster recovery operations. The CLI facilitates easy credential management, including listing, updating, and deleting credentials as needed. Official Portworx documentation highlights pxctl credentials create as the authoritative command for establishing cloud storage access, ensuring security best practices by managing credentials centrally within the Portworx control plane【Pure Storage Portworx CLI Guide source】.

When configuring Portworx to communicate securely with an AWS S3-compatible Object Store using custom SSL certificates, the AWS_CA_BUNDLE environment variable must point to the mounted certificate file location. The correct path for this in the StorageCluster spec is /opt/certs/objectstore.pem. This file contains the Certificate Authority (CA) bundle trusted by Portworx to validate TLS connections to the object store. Ensuring this path is correctly specified and the certificate secret properly mounted is critical to prevent TLS handshake failures and enable secure communication. Portworx documentation and configuration samples specify /opt/certs/objectstore.pem as the standard path for the CA bundle within Portworx containers when integrating with custom or private certificate authorities【Pure Storage Portworx Security Guide source】.
