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 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 is
turned on and has successfully recognized the newly migrated physical
disks, migration operations can continue.
NOTE: Disk groups from multiple storage arrays must 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
may 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.
