Dell PowerEdge RAID Controller S300 - Manual (Page 28)

28 Features
Virtual disk migration The controller supports automatic virtual disk migration
from a PERC S100 adapter to a PERC S300 adapter (or vice
versa). Manual intervention for migration is not required or
used by the PERC S100 adapter or
PERC S300 adapter.
CAUTION: Before starting a virtual disk migration, power-
down both systems before removing or inserting the physical
disks. After the migration occurs, make sure that all of the
physical disks have been migrated and are present in the
virtual disk.
CAUTION: The virtual disk is lost if you perform a virtual disk
migration during an OCE.
NOTE: The PERC S100 adapter only supports SATA HDD and
SATA SSD disks. SAS disks cannot be migrated with a
PERC S100 adapter.
NOTE: A bootable virtual disk cannot be migrated between
dissimilar controllers or dissimilar system models when the
system uses Microsoft Windows Server 2003 as its operating
system.
Virtual disk RAID
levels
Virtual disks at different RAID levels can be created.
Virtual disk
transformation
Virtual disk transformation can consist of:
• Capacity expansion, using OCE (to allocate additional
virtual disk space on the original physical disks or after
additional physical disks are added).
• Rebuilding (rebuilding data on a virtual disk consists of
using an available hot spare or backup physical disk).
