| Steps | Action | Description |
|---|---|---|
| Step 1 | Configure Stretch Sites using the InfoScale Operations Manager Management Server console. | This step includes assigning the site tag to the storage enclosure from the Storage perspective and tagging systems of the required cluster from the Availability perspective of the InfoScale Operations Manager Management Server console. |
| See Configuring stretch sites . | ||
| You can create the disk group (explained in step 2) before or after tagging the enclosure and hosts. Depending on whether the disk group is already configured, step 2 presents two scenarios. | ||
| Step 2 | When the disk group is already configured (with disks from different enclosures) before you perform step 1. | In this scenario, when you tag the enclosure and hosts (as explained in step 1), InfoScale Operations Manager automatically makes the disk group site consistent. |
| Note: Site consistency is also configured through the Configure Stretch Cluster wizard. | ||
| Step 2 | When the disk group is not configured before you perform step 1. | After tagging the enclosure and hosts (as explained in step 1), you can create a new disk group using the InfoScale Operations Manager console. While creating the disk group, an option will be provided to make the disk group site-aware. |
| See Configuring stretch sites . | ||
| Step 3 | Create mirrored volume on the disk group. | Create mirrored volumes on the disk group created above. It is required for end-to-end setup of campus cluster. |
Note: If the site tags are removed using VxVM or VCS command line, InfoScale Operations Manager still shows the site tags on the InfoScale Operations Manager console. To get the updated status, wait for 30 minutes, or refresh the host on the InfoScale Operations Manager console. For more information and instructions on site tag removal, refer toStorage Foundation High Availability Solutions Disaster Recovery Implementation Guide.
