Scenario
StarWind storage cluster on the Primary site with Asynchronous storage replication to the Disaster Recovery site.
Case Study
Primary site is down without any way to start a Production during accepted Recovery Time Objective (RTO).
Case Solution
NOTE: By design, the device on Asynchronous node is LSFS (Log-Structured File System). Snapshots can be mounted only in Read-Only mode.
To restore the Production from a Read-Only Snapshot:
- Connect to the Asynchronous node using StarWind Management Console and mount the snapshot;
- Connect the newly created snapshot device as an iSCSI target in Microsoft iSCSI Initiator;
- Bring the connected disk online in Disk Management;
- Copy the necessary information and import VMs from the mounted Read-Only disk to another storage/location;
- Run the Production using the copied data;
To restore the Production from the replicated device on the Asynchronous node:
- Connect to Asynchronous node using StarWind Management Console and re-add the existing device in a new target having previously removed Asynchronous replica to it;
- Wait for device mounting in StarWind Management Console;
- Connect the newly added device as an iSCSI target in Microsoft iSCSI Initiator;
- Bring the connected disk online in Disk Management;
- Import and Register the necessary VMs in Hyper-V Manager.
