Configuring stretch sites

Last published : Jul 06, 2026
You can use the InfoScale Operations Manager Management server console to configure stretch sites. The following three configurations are supported:
  • For campus cluster, first tag the enclosure with the site name and thereafter, assign the same site tag to the cluster's hosts. Set the required site fencing preferences. Storage Foundation and Cluster Server commands are run for the campus cluster configuration.
  • For replicated data cluster (RDC) configuration, assign site tags for the nodes of the cluster and set the site fencing preferences. Enclosure tagging is not required for RDC configuration. Cluster Server commands are run for the RDC configuration.
  • For mixed mode (a combination of Storage Foundation volume mirroring and array or host-based replication), tag the enclosure with the site name and assign the same tag to the cluster's hosts. Set the required site fencing preferences. Like campus cluster, Storage Foundation and Cluster Server commands are run for the mixed mode.
    Note: The remove site tag operation is not supported through the InfoScale Operations Manager console. Refer to theStorage Foundation High Availability Solutions Disaster Recovery Implementation Guidefor more information.
To configure stretch sites using InfoScale Operations Manager
Note: For campus cluster and mixed configurations, run all the following steps. For RDC configuration (since enclosure tagging is not required), go to the step 3.
  1. In the Management Server console, go to the Storage perspective, and locate the required enclosures. Enclosures from both sites in the InfoScale Operations Manager Management Server domain should be tagged. The disks of these enclosures are or will be a part of the disk groups that are used for the campus cluster.
  2. Right-click the enclosure, and select Assign Sites.
See Enclosure site assignment panel options.
  1. Go to the Availability perspective, and locate the cluster that uses storage from the enclosure. Right-click the cluster and then select Configure Stretch Sites.
  2. In the Specify Cluster Type panel, select the required cluster configuration. Click Next.
See Select cluster type panel options.
  1. In the Assign Sites to Systems panel, select the site tag for each system of the cluster. Click Next.
See Assign site to the systems panel options.
  1. In the Specify Site Fencing Preference panel, set the preferences for the sites.
See Site fencing preference panel options.
  1. Click Finish to complete the site assignment for the systems. In the Result panel clickShow Commands to view all commands that are run for the site configuration operation. If any command fails to run, the wizard does not run subsequent commands.
