Manual Redundancy Restoration

Redundancy to hosts can be manually restored instead of automatically restored. Redundancy can be restored at the server group or virtual disk level.

To manually restore redundancy for 3-copy virtual disks:

  • In the Virtual Disks List, select one or more 3-copy virtual disks, right-click and select Restore Redundancy from the context menu.

The operation is also available from context menus in the DataCore Servers panel, Hosts panel, and in Virtual Disks tabs in Details pages.

To manually restore redundancy for a server group:

  • In the DataCore Servers panel, right-click on the server group and click Restore Redundancy from the context menu.
  • These operations require one active storage source and the inactive storage source in a 3-copy virtual disk to be healthy and online in order to swap the active paths to the inactive storage source. The operations are only performed on virtual disks capable of performing them.
  • These operations can be performed without a full recovery provided that the inactive storage source in the virtual disk is healthy and up-to-date.
  • Automatic self-healing is only performed for 3-copy virtual disks that are served to hosts; virtual disks that are not served to hosts can be manually restored if needed.
  • An inactive storage source in a 3-copy virtual disk cannot be promoted to an active storage source when used as the source of a replication.
  • After the operation is performed and if the failed storage source is permanently failed or unavailable, that storage source may be split to remove it and a new mirror added to make a 3-copy virtual disk fully functional again.
  • Snapshots and rollbacks do not get moved during this operation, but remain on the server where they were created.
  • Mirror recovery can be monitored in the Virtual Disks list in the Summary, or in the Virtual Disk Details page in the Info tab.
