Related Topics

Use this option to set the media scan settings for a single logical drive or for multiple logical drives on a storage subsystem.

Procedure

1

Select a logical drive in the Logical View, then, select either the Logical Drive >> Change >> Media Scan Settings pull-down menu option, or Change >> Media Scan Settings from the right-mouse pop-up menu.

Result: The Change Media Scan Settings dialog is displayed with the current settings for the selected logical drive.

To modify multiple logical drives, select the logical drives in the Select logical drives area:

  • Press Ctrl + click to select nonadjacent logical drives
  • Press Shift + click to select adjacent logical drives
  • Press Select All to choose all available logical drives

Important:

  • If more than one logical drive is selected, the media scan settings default to no settings selected. The current media scan settings are ONLY shown if a single logical drive is selected.
  • Changing the media scan settings using this option modifies the priority for ALL of the logical drives you selected.

2

Select the Enable background media scan check box, and select one of the redundancy check options:

With redundancy check

Use this option to perform a media scan with redundancy check enabled.

A redundancy check scans the blocks in a RAID 3 or 5 logical drive and checks the redundancy information for each block.

- OR -

Compares data blocks on RAID 1 mirrored drives.

Note: RAID 0 logical drives have no data redundancy.

Without redundancy check

Use this option to perform a media scan with redundancy check disabled.

Important: Use the Storage Subsystem >> Change >> Media Scan Settings pull-down menu option to view or change the duration over which a scan will operate. You must set the media scan duration using this option or the media scan will NOT run on the desired logical drives.

Result: A confirmation dialog is displayed.

4

Select Yes.

Result: A progress dialog is displayed indicating the number of logical drives being changed. Select Cancel to stop any further logical drives from being changed.
