• Enabling premium features before migration - Before migrating disk groups and virtual disks, enable the required premium features on the destination storage array. If a disk group is migrated from a storage array that has a premium feature enabled and the destination array does not have this feature enabled, an Out of Compliance error message can be generated. For specific procedures to correct the error, refer to the Recovery Guru. Disk Roaming Moving physical disks within an array is called disk roaming. The RAID controller module automatically recognizes the relocated physical disks and logically places them in the proper virtual disks that are part of the disk group. Disk roaming is permitted whether the RAID controller module is either online or powered off. NOTE: The disk group must be offline before moving the physical disks. Advanced Features The RAID enclosure supports several advanced features: • Storage Partitioning, including host server-to-virtual disk mapping • Virtual Disk Snapshots • Virtual Disk Copy NOTE: Virtual Disk Snapshot and Virtual Disk Copy are premium features that must be activated separately. If you have purchased these features, an activation card is supplied that contains instructions for enabling this functionality. Storage Partitions Storage partitioning enables host servers to share access to virtual disks in a storage array. A storage partition is a logical entity consisting of one or more virtual disks that can be accessed by a single host server or shared among host servers that are part of a host group. To create a storage partition, you first define a host server or host group, then define a host-to-virtual disk mapping. NOTE: You must create a storage partition for each type of host. 42 Using Your RAID Enclosure
