Rebuilding Virtual
Disk
This topic describes the procedure to manually rebuild a degraded virtual disk by using the Marvell BIOS setup utility. This is applicable to the RAID 1 virtual disk.
Important
The rebuild process is both initiated and completed in the Marvell BIOS setup. The Mar- vell RAID Utility (MRU), which runs in as OS environment, cannot be used to either initi- ate, resume, or complete the rebuild process Spare physical disks are not supported.
1.When a virtual disk is degraded, the “Status” of a virtual disk is changed from Func- tional
to Degrade.
2.Replace the faulty physical disk with an identical physical disk. (Note: If an identi- cal 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 BIOS detects the new physical disk and lists the device under “Free Physical Disks” in the [Topology] pane.
3.In the [Topology] pane, scroll to “Virtual Disk” (VD 0: XXXX), and press Enter to select. A menu
