Storage Controller Features 27
The controller detects the RAID configuration from the configuration
data on the physical disks.
Disk Migration
The PERC H700 and H800 cards support migration of virtual disks from
one controller to another without taking the target controller offline.
The controller can import RAID virtual disks in optimal, degraded,
or partially degraded states. You cannot import a virtual disk that is in
an offline state.
NOTE: The source controller must be offline prior to performing the disk migration.
NOTE: Disks cannot be migrated back to previous PERC RAID controllers.
NOTE: Importing secured virtual disks is supported as long as the appropriate key
(LKM) is supplied/configured.
When a controller detects a physical disk with an existing configuration,
it flags the physical disk as foreign, and generates an alert indicating that
a foreign disk was detected.
CAUTION: Do not attempt disk roaming during RLM or online capacity
expansion (OCE). This causes loss of the virtual disk.
Perform the following steps to use disk migration:
1
Turn off the system that contains the source controller.
2
Move the appropriate physical disks from the source controller to the
target controller.
The system with the target controller can be online while inserting the
physical disks.
The controller flags the inserted disks as foreign disks.
3
Use the Dell OpenManage storage management application or the
controller
BIOS Configuration Utility
to import the detected foreign
configuration.
4
Ensure that all physical disks that are part of the virtual disk are migrated.
NOTE: For more information about compatibility, contact your Dell technical
support representative.
