3-16 MegaRAID BIOS Configuration Utility

3.7.2 Viewing and Changing Logical Drive Properties

To view or change logical drive properties, follow these steps:

1. On the Management Menu, select Objects → Logical Drive.

2. Select View/Update Parameters.

The only logical drive properties you can change are Disk WC (Disk

Write Cache) and Read Ahead (see Section 3.3, “Setting the Hard

Disk Write Cache and Read Ahead Policies”). The other properties

are view-only.

3.7.3 Viewing Physical Drive Properties

To view physical drive properties, follow these steps:

1. On the Management Menu, select Objects → Physical Drive.

2. Highlight a physical drive on the list that appears and press Enter.

3. Select Drive Properties from the menu.

The drive properties are Device Type (Disk), Capacity, Product ID,

and Revision No. These properties are view-only.

3.8 Forcing Drives Online or Offline

The MegaRAID BIOS CU enables you to force drives online or offline.

You may want to force a drive of a redundant array offline so that a

hotspare drive will automatically replace it. An auto rebuild will begin

immediately if the MegaRAID BIOS CU finds a valid hotspare drive to

replace the offline drive.

You may need to force a drive online if it has gone offline due to a power

failure. The MegaRAID BIOS CU will not allow a drive to be forced online

if its size is smaller than the defined size of the array.

To force a drive online or offline, follow these steps:

1. On the Management Menu, select Objects → Physical Drive.

2. Highlight a physical drive that is a member of an array and press

Enter.
