Data Synchronization In The Raid System - Siemens SIMATIC IPC677E Operating Instructions Manual

Operating the device
5.3 Operating RAID systems
Integrating a replaced drive in the running system (without restarting the device)
1. Select "Start" > "Intel" > "Intel Rapid Storage Technology".
2. Select the "Status" menu.
The new drive is displayed on the right-hand side of the program window in the "Storage
System View" area.
If the new drive is not shown, click the "Run Hardware Scan now" icon
3. Click on the RAID volume in the "Storage System View" area on the right-hand side of the

5. In the following dialog, select the newly installed drive and click on "Rebuild".
The RAID system data synchronization (Page 64) is started.
5.3.6

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
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:
● < 3h at 90% HDD system load
In addition, system performance may be limited in the case of a manually started
maintenance operation until completion of the maintenance phase.
64
statuses are only achieved after successful completion of synchronization.
