(see 2.9.5 Miscellaneous on page 2-71). You may also schedule periodic
maintenance tasks to do disk scrubbing(see 2.7.9 Scrubbing on page 2-
50) for defected sectors recovery or to do disk self-tests (see 2.7.11
Performing disk self test on page 2-51).
Miscellaneous settings
There are also minor settings that you might need to do, like checking UPS
(see 2.9.4 UPS on page 2-70), time setup (see 2.10.4 System Time on
page 2-76), changing password (strongly suggested) and etc.
Saving the configurations
If you’ve done all the configurations, please save the configurations to
files (human-readable text file for your own reference and binary file for
restoring the configurations if any disaster happens).
1.7 Maintaining the RAID System
Properly configuring RAID systems is a good starting point, but you need
to do regular checking and reconfiguration to make sure your RAID
systems are healthy and delivering the best throughout the lifetime.
• Constantly monitoring RAID system health
You can quickly get an overview of the RAID system health by accessing
the monitoring page of the Web GUI (see 2.2 Monitor Mode on page 2-
5). You probably need to do so only when receiving event notification
email or traps. All the events are described in the Appendix D, each of
which has suggested actions for your reference. You need to watch the
status of chassis components, like fans, power supply units, battery
module, and controller module. You need also check the status of hard
disks, and the I/O statistics (see 2.11 Performance Management on
page 2-81) to know the system loading level and distribution. A hard disk
with long response time or lots of media errors reported could be in
trouble.
• Performing online maintenance utilities
Comprehensive maintenance utilities are offered for ensuring the best
condition and utilization of your RAID systems all through its lifetime. They
include data integrity assurance, capacity resource reallocation, and
RAID attributes migration.
Data integrity assurance
For data long-term integrity assurance and recovery, you may use disk
scrubbing (see 2.7.9 Scrubbing on page 2-50), disk cloning (see 2.7.8
Cloning hard disks on page 2-48), DST (see 2.7.11 Performing disk self test
on page 2-51), and SMART (see s 2.8.1 Hard disks on page 2-57). For how
these can help you, please go to Appendix B: Features and Benefits.
