Rebuilding Virtual Disk

This topic describes the procedure to manually rebuild a degraded virtual disk. This is applicable to the RAID 1 virtual disk created with the 88SE91xx controller.

Note: The 88SE91xx BIOS supports manual rebuilding of RAID 1 virtual disks. The rebuild process is both initiated and completed in the BIOS. The Marvell Storage Utility (MSU), which runs in an OS environment, cannot be used to either initiate, resume, or complete the rebuild process. Spare physical disks are not supported.

To manually rebuild a RAID 1 virtual disk

1.  When a virtual disk is degraded, the Status of a virtual disk is changed from Functional to Degrade, as shown in Figure 1.

2.   Replace the faulty physical disk with an identical physical disk.

Note: If an identical disk is unavailable, use a replacement physical disk of larger size or one with a slightly smaller size as determined the Gigabyte Rounding setting for the virtual disk.

The 88SE91xx detects the new physical disk and lists the device under Free Physical Disks in the Topology pane, as shown in Figure 2.

3.  In the Topology pane, scroll to Virtual Disks (VD 0: New_VD in Figure 3), and press Enter to select. A menu pops-up, as shown in Figure 3.

Scroll to Rebuild and press Enter to configure the rebuild process.

4.   Scroll through the list of free disks, as shown in Figure 4, and press Space to select or unselect a replacement physical disk.

Press Enter to continue.

5.  Press Y to select Yes, as shown in Figure 5, when prompted to confirm the rebuild process.

6.  The status of the Rebuild process is reflected in the properties of the virtual disk, as shown in Figure 6.

To pause the rebuild process

1.  In the Topology pane, scroll to the partially rebuilt Virtual Disk.

2.  Press Enter to view available operations on Virtual Disk.

3.  Scroll to Pause and press Enter to pause the rebuild process.

Note: Incomplete rebuild procedures are paused upon exiting the BIOS. The rebuild procedure can be resumed manually upon re-entering the BIOS.

To resume the rebuild process

1.  In the Topology pane, scroll to the partially rebuilt Virtual Disk.

2.  Press Enter to view available operations on Virtual Disk.

3.  Scroll to Resume and press Enter to resume the rebuild process.

Note: The rebuild process is both initiated and completed in the BIOS. The Marvell Storage Utility (MSU), which runs in an OS environment, cannot be used to either initiate, pause, resume, or complete the rebuild process.
