Example: Volume migration using Arctera InfoScale Operations Manager

Typical data center storage allocation tasks require you to quickly allocate storage to multiple hosts while maintaining optimum storage utilization. These tasks also involve migrating volumes. The Storage Provisioning and Enclosure Migration Add-on lets you perform the following tasks:

Template-based storage provisioning: An efficient method to provision storage (with predefined configurations) to the required hosts in your data center. You can create new storage template from volumes or file systems, and use the template to provision storage on the managed hosts.
Migration of volumes: You can migrate the volumes by host, enclosure or by disk groups. While migrating, you can specify various attributes of the involved storage objects. For example, LUN characteristics (thick or thin), media (SSD or HDD), RAID type, and target layout (concat, striped).

This topic provides an overview of the steps that you need to typically perform to use the volume migration functionality (by host) in Arctera InfoScale Operations Manager. To perform this task, your user group must be assigned the Admin role on the host or the Server perspective. The permission on the host may be explicitly assigned or inherited from a parent Organization.

You also need to verify the following:

If volumes have been set up for creating snapshots, unprepare those volumes.
Ensure that disks are provisioned on the new enclosures and are added to the disk group.
Ensure that the enclosures are added to Arctera InfoScale Operations Manager.

To migrate volumes by host

In the Management Server console, go to the Server perspective, expand Solutions in the left pane, and click Storage Migration.
In the Actions pane, click Migrate Volumes By Host.
In the Migrate Volumes By Host wizard, specify a name and description for the migration task so that you can track the task status. Click Next.
Select the host and then select the source enclosure. Click Next.
Select one or more enclosures as the targets to which you want to migrate the volumes.
Under Select LUN Characteristics, specify the LUN requirements. It includes selecting enclosure vendor, LUN type (thick, thin, or any), media type (SSD or HDD), LUN classifications, and replication status. Click Next.
Select the volumes to migrate. Verify the source and target layout. If you want to change the target layout, double-click the volume and select the new layout on the Change Layout window.
You can also choose from the following options:
- Keep the same number of paths to the volume (the default) or set a minimum number of paths.
- Optionally, select the check box to delete the original volumes after successfully migrating the volumes to the target enclosure.
Click Next.
Choose one of the following:
- Schedule the time of the migration.
- To run immediately, select Run now.
  Warning:
  You may want to view the Impact Analysis report that is generated by the wizard before you run the migration.
Click Next.
The wizard generates the Impact Analysis report. It provides the details of the objects that are associated with the volumes being migrated.
View the report and click Previous if you want to go back and change anything. Otherwise, click Finish and close the confirmation window.
Scheduled migrations are listed on the Migration Status (By Schedule) tab. You can check on the status of a specific volume on the Migration Status (By Volume) tab.
