Configuration: Disk Groups and Virtual Disks

• Redundancy mismatches error—The first 10 redundancy mismatches that 

are found on the virtual disk are reported to the event log.

• Unfixable error—Data could not be read and parity or redundancy 

information could not be used to regenerate the data. For example, 

redundancy information cannot be used to reconstruct the data on a 

degraded virtual disk. The error is reported to the event log. 

For more information, see the PowerVault Modular Disk Storage Manager 

online help topics.

To change the media scan settings:

1 In the AMW, select the Logical tab and select any virtual disk.
2 Select Virtual Disk Change Media Scan Settings.

The 

Change Media Scan Settings window is displayed.

3 Deselect Suspend media scan if selected.
4 In Scan duration, enter or select the duration (in days) for the media scan.

The media scan duration specifies the number of days for which the media 

scan runs on the selected virtual disks.

5 To disable media scans on an individual virtual disk, select the virtual disk 

in the 

Select virtual disks to scan area, and deselect Scan selected virtual 

disks.

6 To enable media scans on an individual virtual disk, select the virtual disk 

in the 

Select virtual disks to scan area, and select Scan selected virtual 

disks.

7 To enable or disable the consistency check, select either With consistency 

check or Without consistency check.

A consistency check scans the data blocks in a RAID Level 5 virtual 

disk, or a RAID Level 6 virtual disk and checks the consistency information for 

each block. A consistency check compares data blocks on RAID Level 1 

mirrored physical disks. RAID Level 0 virtual disks have no data consistency.

8 Click OK.
