7.5 Notes on operation
SIMATIC Box PC 627
7-8 Operating Instructions, Release 05/2006, A5E00362052-03
The data on the hard disk specified as the source drive will now be copied to the partner
drive. The time required to copy the data (migration) depends on the capacity of the hard
disk and may take approximately 45-90 minutes. The device can continue to operate during
the copy process although at a reduced speed. The data mirroring first goes into effect when
the copying process is successfully completed. The device will then be operating in the
specified RAID 1 mode and the data will be saved on both hard disks.
Note
Information about the operation of the RAID system can be found in the RAID user manual
on the supplied SIMATIC PC Documentation and Drivers CD.
Notice
The security functions of the RAID system take effect without starting the RAID software.
The RAID status is always indicated in the Windows status bar.
In the event of an error, a hard disk can be duplicated by means of the RAID Controller BIOS
or on the operating system level. It may take up to several hours to synchronize a new disk
in the background, depending on the size of the hard disk and on the system load.
The redundant system state RAID 1 is reached again only after synchronization is
completed.
