4.3.5 Hot-plug Drive Support
Hot-plug support allows hard drives to be inserted or removed without rebooting the system, as
long as both the hard drive and server system backplane support hard drive hot-plug functions.
The RAID controller immediately recognizes when a drive is removed and sets the virtual status
to “Missing” until an I/O to the drive fails. The drive status then changes to “Failed.”
A drive inserted into an attached intelligent enclosure is recognized as present. A drive inserted
into an attached non-intelligent enclosure may require a bus scan before it is detected. Hot plug
of new drives is supported in both intelligent 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 drive of the same or larger size is inserted into the same slot,
the new drive is automatically marked as a hot-spare drive and a rebuild begins. A bus scan
may be required in a non-intelligent enclosure.
4.3.7 Physical Drive Roaming
Physical drive roaming allows the user to move drives to any port on the RAID controller without
losing the configuration.
4.3.8 Virtual Drive Roaming
Virtual drive roaming allows the user to move a virtual drive from one controller to another
system/controller without losing the configuration or data. All virtual drives attached to the RAID
controller must be moved as a unit.
4.3.9 RAID Controller Migration
The RAID controller migration feature allows a defective RAID controller to be removed and
replaced by a compatible RAID controller without losing the configuration or data. To avoid a
configuration mismatch, it is wise to reset the new controller configuration before 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 a virtual drive in an
array. OCE is available as an option in the Intel
®
BIOS Console 2 utility, the Intel
®
RAID Web
Console 2 utility, or the command-line utility.
4.3.11 RAID Level Migration
RAID level migration allows for the migration from one RAID level to another. RAID level
migration may require the addition of additional physical drives as part of the process. RAID
