50 Planning: MD3200 Series Storage Array Terms and Concepts• Migrating virtual disks to a storage array with no existing physical disks—Turn off the destination storage array, when migrating disk groups or acomplete set of physical disks from a storage array to another storage arraythat has no existing physical disks. After the destination storage array isturned on and has successfully recognized the newly migrated physicaldisks, migration operations can continue.NOTE: Disk groups from multiple storage arrays must not be migrated at thesame time to a storage array that has no existing physical disks.• Enabling premium features before migration—Before migrating diskgroups and virtual disks, enable the required premium features on thedestination storage array. If a disk group is migrated from a MD3200storage array that has a premium feature enabled and the destination arraydoes not have this feature enabled, an Out of Compliance error messagemay be generated.Disk RoamingYou can move physical disks within an array. The RAID controller moduleautomatically recognizes the relocated physical disks and logically placesthem in the proper virtual disks that are part of the disk group. Disk roamingis permitted when the RAID controller module is either online or poweredoff.NOTE: The disk group must be exported before moving the physical disks.Advanced FeaturesThe RAID enclosure supports several advanced features:• Virtual Disk Snapshots• Virtual Disk Copy• High Performance TierNOTE: Virtual Disk Snapshot, Virtual Disk Copy, and High Performance Tier arepremium features that must be activated separately. If you have purchased thesefeatures, an activation card is supplied that contains instructions for enabling thisfunctionality.
