2. Patrol Read
Patrol read performs a read & verify test on the entire area of the HDD. It can be performed for all HDD
‟s
assigned to virtual disks and hot-spare disks.
Patrol read allows defects of the HDD
‟s to be detected and repaired.
For HDD
‟s configuring redundant virtual disks or those assigned to hot-spare disks, error sectors detected
during patrol read can be repaired.
Notice
Note the following for the patrol read:

The patrol read feature is factory-set to "Disabled."

To utilize patrol read, MSM must be installed.

If the system is restarted, the patrol read is aborted. After restart of the
system, the patrol read runs from the first step (top of HDD).

For the detailed operation, refer to the "MegaRAID Storage Manager
User
‟s Guide" on the NEC EXPRESSBUILDER CD-ROM that comes
with the server.
3. Consistency Check
Consistency check is used to check the consistency among virtual drives. It is available for redundant virtual
drives in RAID1.
Consistency check can be performed through WebBIOS or MSM.
Consistency check also repairs error sectors. Accordingly, it can be used for preventive maintenance.
Notice
Note the following for the consistency check:

During the consistency check, the responsiveness of the server
decreases due to high load.

If the system is restarted, the consistency check is aborted. However,
the consistency check resumes after restart.

For the detailed operation, refer to the "MegaRAID Storage Manager
User
‟s Guide" on the NEC EXPRESSBUILDER CD-ROM that comes
with the server.
