Patrol Read
The patrol read gives the read & verify test in the entire area of HDDs. It can be performed for all
HDDs assigned to virtual drives.
The Patrol Read allows subsequent detects of HDDs to be detected and repaired.
For HDDs configuring redundant virtual drives, error sectors detected during Patrol Read can be
repaired.
IMPORTANT:
For the RAID Controller, Patrol Read feature is factory-set to
"Enabled".
To change settings of Patrol Read, use Universal RAID Utility.
If the system is restarted while running Patrol Read, Patrol Read
resumes from that point.
Consistency Check
The Consistency Check is used to check consistency among virtual drives. It is available for
redundant virtual drives except for RAID0. It is also available for host spare.
Consistency Check can be performed through WebBIOS or Universal RAID Utility.
Consistency Check performs not only consistency check but also repair of error sectors.
Accordingly, it can be used as preventive maintenance.
IMPORTANT:
During Consistency Check, the processing rate is decreased due to
much load.
If the system is restarted, the Consistency Check is aborted.
However, the Consistency Check resumes after restart.
To schedule execution of Consistency Check, use WebBIOS, not the
Universal RAID Utility
