The correct sequence of steps to create a Windows volume backup using the Microsoft VSS Framework with an XtremIO cluster is as follows:

Requestor interacts with the VSS service to start the backup.

VSS service sends a Freeze request to the Writer.

Provider creates an XVC of the file system and exposes the volume to the host.

VSS service sends a Thaw request to the Writer.

Requestor uses the XVC to back up the content of the volume.

The Requestor, typically a backup application, initiates the process by interacting with Microsoft’s Volume Shadow Copy Service (VSS) to commence a snapshot backup.

The VSS service then issues a Freeze request to its Writers, which are responsible for ensuring data consistency for applications during backups.

An XtremIO Provider, which interfaces between the XtremIO storage and VSS, creates an XtremIO Virtual Copy (XVC) of the file system. This copy is then made accessible to the host system for backup purposes.

After the XVC is created, the VSS sends a Thaw request to the Writers, allowing them to resume normal operations while maintaining data integrity.

Finally, the Requestor uses the XVC to back up the content of the volume, ensuring a consistent and recoverable backup is made.

Please note that this sequence is based on the standard operation of Microsoft VSS with storage systems like XtremIO and should be verified against the most current Dell XtremIO Deploy Achievement documentation for any updates or specific instructions related to your environment.

Understanding XtremIO X1 DAE Power Cables: The Disk Array Enclosure (DAE) power cables are critical components in ensuring that the storage system remains operational. Removing these cables disconnects power to the DAE, which should only be done under specific circumstances.

Scenarios for Power Cable Removal:

Normal Shutdown Procedure: In a normal shutdown, the system is powered down gracefully using management interfaces and proper shutdown commands. Physical removal of power cables is typically not part of this process.

Shutdown after Initial Installation: After the initial installation, the system is powered on and configured. A shutdown would again follow a graceful procedure and not involve removing power cables unless there's a specific issue.

Shutdown due to Power Loss: In the event of power loss, the system would already be down, and there would be no need to remove the power cables as the system has lost power.

Emergency Shutdown Procedure: In an emergency, where the system must be immediately powered down to protect data or hardware, it may be necessary to remove the power cables quickly.

Best Practices and Safety:

Removing power cables as part of an emergency shutdown is typically a last resort measure when immediate power disconnection is required to prevent damage or ensure safety.

Following manufacturer guidelines for emergency shutdown ensures that the system is protected and can be safely restarted when the emergency is resolved.

The XtremIO Management Server (XMS) requires DNS configuration to resolve Fully Qualified Domain Names (FQDN) used in ESRS (Electronic Support Services) configurations. If the DNS is not configured on the XMS, it will not be able to resolve the ESRS FQDN, leading to a failure in connecting home. Configuring DNS on the XMS ensures that all network addresses, including the ESRS server, can be resolved correctly.
