5.4.4.4 Integrating a hot-spare drive into an onboard RAID system
The onboard RAID system is configured in the delivery state in such a way that a new hot-
spare drive is automatically integrated.
If the automatic integration of a drive in the onboard RAID system has been deactivated
(Page 80)or the hot spare drive has been replaced in an onboard RAID system, then you must
integrate the new drive manually.
Requirement
A new drive was used in the onboard RAID system.
Procedure
1. Select "Start" > "Intel" > "Intel Rapid Storage Technology".
2. Click "Run Hardware Scan now".
The new drive is found and displayed.
3. Select the new drive under "Storage system view" and select "Mark as Spare" option under
"Manage disk".
4. Confirm the warning message in the "Mark as Spare" window with "Yes".
5.4.5 Data synchronization in the RAID system
NOTICE
Danger of incorrect operations on machine and plant: delayed system reaction during
data synchronization
Data is synchronized if a drive fails.
The system can respond with a delay depending on the size of the drive and system load. In
extreme cases, the execution of keyboard, mouse or touch screen commands may be briefly
delayed.
The result may be faulty operations of the machine or plant.
•
Do not operate safety-critical functions during synchronization of a drive. Stable system
statuses are only achieved after successful completion of synchronization.
Duration of data synchronization
The synchronization process may take quite some time, e.g. several hours, with extremely
high drive load even days.
Guide value for the duration of data synchronization:
•
< 3 h with 90% HDD system load and RAID5 with HDD 1 TB.
In addition, system performance may be limited in the case of a manually started
maintenance operation until completion of the maintenance phase.
