Rebuilding of Drive X Completed Successfully. Press Esc. (X

= the ID of the rebuilt drive.)

4.Press ESC to display the MANAGEMENT menu.

The state of the rebuilt disk drive changes from FAIL to ONLIN.

If the CU detects a media error on the source drive during rebuild, it initiates a sector read for that block.

If the sector read fails, the CU adds entries to the Soft Bad Block Management (SBBM) table, writes this table to the target drive, and displays an error message. Additional error messages are displayed if the SBBM table is 80% full or 100% full. If the SBBM table is completely full, the rebuild operation is aborted, and the drive is marked as FAIL.

If you press ESC while the rebuild is running, the following options display:

•Stop: (Available only if AutoResume is enabled on the adapter: MANAGEMENT MENU J OBJECTS J ADAPTER J AUTORESUME) The rebuild is stopped, and the CU stores the percentage of the rebuild already completed. If AUTORESUME is enabled, and if FAST INIT is not enabled, the rebuild resumes where it left off when you restart it instead of starting over from 0 percent.

•Continue: The rebuild continues normally.

•Abort: The rebuild is completely aborted. If you restart the rebuild, it begins at 0 percent.

4-5 Hot Plug Support

MegaRAID BIOS CU supports hot plugging of disk drives. When you insert or remove a disk drive, the following hot plug message appears:

A Drive Has Been Inserted/Removed. Configuration Updated.

Press ESC...

After you press ESC the inserted or removed drive will be reflected in the list of drives that appears in the configuration utility.

Obviously, you should not insert or remove a drive while you are defining a new virtual drive or while an initialization or other process is running. The following information describes how the CU handles hot plugging when various actions occur:

•If the PHYSICAL DRIVE window or one of the CONFIGURATION windows is open when you insert or remove a drive, the window will close when the hot plug message appears.

•CU menus such as SELECT BOOT DRIVE, SELECT ADAPTER and VIRTUAL DRIVE will completely or partially close when a drive is inserted or removed.

•If a Rebuild is in progress when you insert or remove a drive, the CU first displays the message:

Rebuilding Of Drive Not Complete! Press Esc..

followed by the hot plug message.
