Using the Rescan and Reactivate commands to restore a disk marked as "Missing" or "Offline" using VERITAS Volume Manager (tm) for Windows 2000

Solution



There are several reasons why a disk may be marked as missing or offline. They include a disk that may be corrupted, powered down, intermittently unavailable, or simply disconnected. Take the necessary steps to repair any disk or controller problems and ensure that the disk is turned on, plugged in, and attached to the computer. Then, use the "Rescan" command to rescan the devices on the SCSI bus. To execute the rescan command, follow these steps:

Note: The images below depict the menu selections for Volume Manager 2.7 for Widows 2000. The menu selections for Volume Manager 3.0 and 3.1 for Windows 2000 will present additional selections, however, the steps outlined here are the same for all versions.

1. Right click the computer icon in the tree view of the Volume Manager screen  
2. Select Rescan from the menu that displays (Figure 1). If there are several devices on the computer's SCSI bus, the rescan may take several minutes.

Occasionally, a Rescan will not clear error flags on a dynamic disk. When this happens, use the "Reactivate Disk" command to clear these flags. The Reactivate Disk command performs a manual restart on a disk. Dynamic disks that are marked as missing or offline may be reactivated. After reactivation, a disk should be marked as "Online" if they are attached and are not in a failed condition.

To perform a disk reactivation, follow these steps:  

1. Right click the disk with the error flags and select Reactivate Disk from the context menu that appears (Figure 2). A dialog box will display.

2. Choose which disk to reactivate by checking the box associated to the disk and clicking OK. The disk should be marked as Online after the disk is reactivated unless there is a mechanical or other serious problem with the disk (Figure 3).
