BEST PRACTICES Shutting Down „ Unclean shutdowns are hard on RAIDed systems. The WD Sentinel server recognizes an unclean shut down and upon the reapplication of power, begins a long sequence of examining the RAID for errors and bringing the RAID configuration back into alignment. This sequence can take many hours. To avoid this situation and to assure that the unit always experiences clean shutdowns and the best data integrity, use an Uninterruptible Power Supply (UPS). Note: Performance is affected during a RAID rebuild and verification. „ Before shutting down the server, stop any backups currently running. „ To avoid possible corruption, do not unplug the power from the unit while it is running.

ADMINISTRATOR’S GUIDE
Shutting Down
Unclean shutdowns are hard on RAIDed systems. The WD Sentinel server
recognizes an unclean shut down and upon the reapplication of power,
begins a long sequence of examining the RAID for errors and bringing the
RAID configuration back into alignment. This sequence can take many hours.
To avoid this situation and to assure that the unit always experiences clean
shutdowns and the best data integrity, use an Uninterruptible Power Supply
(UPS).
Note:
Performance is affected during a RAID rebuild and verification.
Before shutting down the server, stop any backups currently running.
To avoid possible corruption, do not unplug the power from the unit while it is
running.
