Integrated RAID Controller SRCS14L

4.3.4

Auto-detection of Hot-Plug Disk Drives in a Non-Intelligent

Drive Enclosure

This is a special feature that allows the use of non-intelligent disk enclosures (requires truly hot-

pluggable disk drives and backplane connectors) as though they were intelligent enclosures. This

feature is configurable and allows the user to set up non-intelligent enclosures to detect the

insertion or removal of hot plug disk drives and report the event to the RAID firmware. The RAID

configuration is automatically updated to the new configuration. Access this feature through the

Advanced Setup

menu of Storage Console.

4.3.5

Auto-declare Hot Fix (Spare) Drive

If the RAID controller has a RAID array drive that is in

failed (degraded) state

, and you connect to

the controller a new hard disk drive that is the same size or larger than the smallest disk drive in

that

failed (degraded)

RAID array then the RAID firmware will automatically mark this new disk

drive as a

hot fix (spare) drive

for the

failed (degraded)

RAID array drive

.

Rebuild

will then

automatically commence. If the new hard disk is smaller than the smallest hard disk drive in the

failed (degraded)

RAID array drive

, the new disk drive will not be marked as a spare and the

failed

(degraded)

RAID array drive

will remain

failed (degraded)

. When a non-intelligent enclosure that

has not been configured for auto-detection of hot plug disk drives is used, a bus scan or reboot is

required for the

Auto Declare Hot Fix

feature to commence.

4.3.6

RAID Array Drive Roaming

Array Roaming allows the user the ability to move a complete RAID array from one computer

system (for example, computer #1) to another computer system (computer #2) and preserve the

RAID configuration information and user data on that RAID array. Computer #2 must also have an

SRCS14L controller installed. RAID arrays set up with an SRCS14L controller cannot roam to

computers that use other controllers.

Note:

For a migrated RAID array to be recognized by the new host operating system, the host system

may need to be rebooted.

Warning:

RAID arrays set up with an SRCS14L controller cannot roam to computers that use other

controllers (anything other than the SRCS14L). Unpredictable behavior may include, but is not

limited to, data loss or corruption.

4.3.7

On-line RAID Array Configurations

4.3.7.1

Capacity Expansion Without Reboot

On-line capacity expansion refers to the ability of the RAID controller to present new storage space

to the host OS without requiring that the computer system must be taken off-line and rebooted (for

those Operating systems that support this feature). The host OS is able to detect the new capacity

and format and partition it for immediate use. The RAID controller offers several ways of creating

additional capacity while on-line.
