Planning: MD3200i Series Storage Array Terms and Concepts

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. Use cold

virtual disk migration for the disk groups from one storage array.

• 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 MD3200i

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.
