The command pxctl list autopilotrules is used to list all Autopilot rule objects across namespaces within a Portworx cluster. Autopilot rules define automated policies for storage operations like scaling and volume migration. This CLI command queries the Portworx control plane to retrieve and display all configured Autopilot rules, regardless of the Kubernetes namespace they reside in. Using kubectl commands alone is insufficient because Autopilot rules are managed internally by Portworx and may not correspond directly to Kubernetes resources. Official Portworx CLI documentation confirms pxctl list autopilotrules as the primary command for comprehensive Autopilot rule enumeration, enabling administrators to audit and manage storage automation policies efficiently【Pure Storage Portworx Autopilot Guide†source】.

To perform an ApplicationBackup in Portworx, two Kubernetes Custom Resource Definitions (CRDs) are essential: BackupLocation and ApplicationBackup. The BackupLocation CRD defines the target backup storage, such as an S3 bucket or NFS share, including credentials and endpoints. ApplicationBackup defines the specifics of the backup operation, including which application volumes to back up, schedules, and retention policies. Together, they enable declarative backup management within Kubernetes, allowing administrators to configure, automate, and monitor backups of stateful applications using Portworx. These CRDs provide flexibility and integration with Kubernetes-native tools, improving disaster recovery capabilities. Portworx backup documentation describes these CRDs as the foundation of its application-aware backup and restore system【Pure Storage Portworx Backup Docs†source】.

To migrate data from an existing PVC backed by another storage provider to a new Portworx PVC, the administrator typically creates a temporary pod (often using a lightweight container like busybox) that mounts both the source and destination PVCs. Within this pod, standard Linux file commands such as cp or rsync are used to transfer data between volumes. This approach leverages Kubernetes volume mounting capabilities and avoids downtime by enabling data migration without removing the source volume immediately. Portworx does not provide a direct pxctl import command, nor does it use a DataExport Cluster Resource for PVC data migration. This manual method is widely documented and recommended for stateful data migration tasks involving Kubernetes PVCs across different storage backends【Pure Storage Portworx Data Migration Guide†source】.
