Configuration: Disk Groups and Virtual Disks 151Exporting a Disk GroupOn the source storage array:1 Save the storage array configuration.2 Stop all I/O and unmount or disconnect the file systems on the virtualdisks in the disk group.3 Back up the data on the virtual disks in the disk group.4 Locate the disk group and label the physical disks.5 Place the disk group offline.6 Obtain blank physical disk modules or new physical disks.On the target storage array:1 Verify that the target storage array has available physical disk slots.2 Verify that the target storage array supports the physical disks that youimport.3 Verify that the target storage array can support the new virtual disks.4 Verify that the latest version of firmware is installed on the RAIDcontroller module.Import Disk GroupThe import disk group operation adds the imported disk group to the targetstorage array. After you complete the import disk group operation, all of thephysical disks have Optimal status. Any associated virtual disks or freecapacity nodes are now shown in MDSM installed on the target storage array.NOTE: You lose access to your data during the export/import process.NOTE: You must export a disk group before you move the disk group or import thedisk group.Importing a Disk GroupNOTE: You must insert all of the physical disks that are part of the disk group intothe enclosure before the disk group can be imported.On the target storage array:1 Insert the exported physical disks into the available physical disk slots.
