Intel® RAID Controller SRCSAS18E RAID Functionality and Features

Revision 1.01

Intel order number D61769-001

4.3.5 Hot-Plug Drive Support

Hot plug support allows hard disk drives to be insterted or removed from an enclosure without

rebooting the system, as long as both the hard disk drive and server system backplane support

hard drive hot plug functions.

The RAID controller will immediately recognize that a drive is removed and will put it into a

virtual status of “Missing” until an I/O to the drive fails. The drive will then be changed to the

status of “Failed.” A drive inserted into an attached intelligent enclosure will be recognized as

present. A drive inserted into an attached non-intelligent enclosure may require a bus scan to

be detected. Hot plug of new drives is supported in both intelligent (SAF-TE) and non-intelligent

enclosures.

4.3.6 Auto-declare Hot Spare Drive

If the RAID controller has a RAID array drive that is in a failed (degraded) state and the failed

drive is removed and a new hard disk drive of the same size of larger is inserted into the same

slot, the new drive will automatically be marked as a hot spare drive and a rebuild will begin

automatically. A bus scan may be required in a non-intelligent enclosure.

4.3.7 Physical Drive Roaming

This feature allows the user to move drives to any port on the RAID controller without loss of

configuration.

4.3.8 Virtual Drive Roaming

This feature allows the user to move a Virtual drive from one controlle to another

system/controller without loss of configuration or data. All virtual drives attached to the RAID

controller must be moved as a unit.

4.3.9 RAID Controller Migration

This feature allows a defective RAID controller to be removed and replace by a compatible

RAID controller without loss of configuration or data. To avoid a configuration mismatch, it is

wise to reset the new controller configuration prior to attaching the array drives. If a

configuration mismatch occurs care must be taken to use the configuration on the drives or all

data may be lost.

4.3.10 Online Capacity Expansion

Online capacity expansion (OCE) allows additional drives to be added to an array and the

added capacity can be added to the virtual drive. OCE is available as an option in BIOS

Console 2 utility, RAID Web Console 2 utility, or Command Line utility.
