The specified object no longer exists.

Solution



This TechNote focuses on the Remove function within Volume Manager. See the Related Documents section of this TechNote for information on how to use the Reactivate function

A dynamic disk group is created with three disks. Disk View is selected within Volume Manager (Figure 1).

Figure 1 - Disk View Normal
 

At this point, one of the three dynamic disks is physically removed and a rescan is performed. When the rescan has completed, Disk View will show (Figure 2).

Figure 2 - Disk View Failed
 

An attempt is made to remove the missing disk using these steps:

1. Right-click on Missing Disk
2. Select Remove Disk

An error message will display (Figure 3).

Figure 3 - Error Message
 

To effectively remove the disk in this scenario, it will be necessary to do the following:

1. Shut down and restart the computer
2. Launch the VERITAS Volume Manager application
3. Select Disk View. The screen will be similar to Figure 4 below. Notice the differences between this image and what was displayed in Figure 2 above.

Before you can remove the disk, you must delete all volumes on the disk. Deleting a volume destroys the data in that volume, so you should remove a disk only if you are absolutely certain that the disk is permanently damaged and unusable.
4. Right-click on the volume contained within the missing disk. (Figure 4a)
5. Select Delete Volume. You will be presented with an informational message stating all data will be lost.
6. Click Yes. After a short period, the displayed volume information will change (Figure 5).

7. Right-click on Missing Disk (Figure 5a)
8. Select Remove Disk

The dynamic disk is now removed from the system.
