Dell MD3200, MD3220 owner manual Advanced Features, Disk Roaming

•Migrating virtual disks to a storage array with no existing physical disks— Turn off the destination storage array, when migrating disk groups or a complete set of physical disks from a storage array to another storage array that has no existing physical disks. After the destination storage array has been turned on and has successfully recognized the newly migrated physical disks, migration operations can continue.

NOTE: Disk groups from multiple storage arrays should not be migrated at the same time to a storage array that has no existing physical disks.

•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 MD3200 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.

Disk Roaming

You can move physical disks within an array. 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 when the RAID controller module is either online or powered off.

NOTE: The disk group must be exported before moving the physical disks.

Advanced Features

The RAID enclosure supports several advanced features:

•Virtual Disk Snapshots

•Virtual Disk Copy

•High Performance Tier

NOTE: Virtual Disk Snapshot, Virtual Disk Copy, and High Performance Tier 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.
