Dell PowerStore Protecting Your Data

Remote backup, retrieve, and instant access sessions, go through various states that indicate the sessions progress and possible issues.

The session possible states are:

• Initializing—The session is being created. After creation is completed, the status changes to Idle.
• Idle—No data is transferred to the remote appliance. The session remains in Idle state until the scheduled remote backup rule is triggered, or if you initiate a manual backup.
• Prepare—The PowerStore system is preparing to perform a backup. If there are multiple active sessions, the session may remain in Prepare state until it reaches the top of the queue.
• IO Forwarding (applies only to instant access sessions)—The session is forwarding the host I/O.
• In Progress—The system creates the backup on the remote system. During this state, you can click the status link to monitor the backup progress and view more details.
• Completed (applies only to retrieve sessions)—The session is successfully completed.
• System Paused—Nondisruptive upgrade or migration paused the session.
• Paused—The session is paused.
• Cancelling—The session is being cancelled.
• Cancelled—The session was explicitly cancelled. Sessions in Prepare, In Progress, and Paused states can be cancelled.
• Deleting—The session is being deleted.
• Failed—The session has failed to create the backup.
• Rollback in Progress—An error occurred while the session was active and changes are reverted.
• Failed Cleanup Required—An error occurred while changes were reverted (as a result of a previous error). The cleanup service, which runs periodically, automatically resolves the problem and the session state is changed to Failed. For remote backup sessions, scheduled backups cannot run while the session is in this state.
• Cancel Cleanup Required—An error occurred during the session cancel operation. The cleanup service, which runs periodically, automatically resolves the problem and the session state is changed to Canceled. For remote backup sessions, scheduled backups cannot run while the session is in this state.
• Cleanup Required—The session is successfully completed, but an error occurred during the local cleanup phase. The cleanup service, which runs periodically, automatically resolves the problem and the session state is changed to Idle or Completed. For remote backup sessions, scheduled backups cannot run while the session is in this state.
• Cleanup In Progress—A cleanup is in progress.
