Disk Group Migration Disk group migration allows to you export a disk group so that you can import the disk group to a different storage array. You can also export a disk group so that you can store the data offline. NOTE: During the export process (before the disk group is imported) you lose access to the data on the exported disk group. NOTE: You must export a disk group before you move the disk group or import the disk group. Export Disk Group The export disk group operation prepares the physical disks in the disk group for removal. You can remove the physical disks for offline storage, or you can import the disk group to a different storage array. After you complete the export disk group operation, all of the physical disks are offline. Any associated virtual disks or free capacity nodes are no longer shown in MDSM. Non-Exportable Components You must remove or clear any non-exportable settings before you can complete the export disk group procedure. Remove or clear the following settings: • Persistent reservations • Host-to-virtual disk mappings • Virtual disk copy pairs • Snapshot virtual disks and snapshot repository virtual disks • Remote mirror pairs • Mirror repositories Exporting a Disk Group On the source storage array: 1 Save the storage array configuration. 2 Stop all I/O, and unmount or disconnect the file systems on the virtual disks in the disk group. 3 Back up the data on the virtual disks in the disk group. 130 Configuration: Disk Groups and Virtual Disks
