Dell S300, S100 manual Virtual disk, Migration during an OCE

Table 3-1. Features of the PERC S100 controller and PERC S300 controller (continued)

RAID Controller Feature	Description
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	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).
