2.Select a virtual drive, if there is more than one configured, and press ENTER.

3.Select INITIALIZE from the submenu and press ENTER.

4.Select YES at the prompt and press ENTER.

The CU displays a bar graph showing the initialization progress.

5.When initialization completes, press ESC to return to the previous menu.

If you press ESC while initialization is in progress, the STOP, CONTINUE, and ABORT options are available, as explained earlier in "First Initialization Method", step 5 above.

4-3 Setting the Hard Disk Write Cache and Read Ahead Policies

You can use the MegaRAID BIOS CU to set the hard disk drive Write Cache and Read Ahead settings. Any read or write cache policy changes apply to all virtual drives on an array. In other words, if two virtual drives are defined on a single array and you change the Read Ahead setting on one virtual drive, the change will also apply to the other virtual drive on the array.

The Disk Write Cache and Read Ahead policies can be set to ON or OFF.
