Planning: MD3600f Series Storage Array Terms and Concepts

55

• 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 MD3600f

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
• Remote Replication (this premium feature is supported only in storage

arrays with the Fibre Channel [FC] host ports)

NOTE:

Virtual Disk Snapshot, Virtual Disk Copy, High Performance Tier, and Remote

Replication 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.

Host Server–to–Virtual Disk Mapping

The host server attached to a storage array accesses various virtual disks on the

storage array through its host ports. Specific virtual disk-to-LUN mappings to

an individual host server can be defined. In addition, the host server can be part

of a host group that shares access to one or more virtual disks.
