To bring a disk that is Offline but not Missing back online 1. In Disk Management, use the Reactivate Disk command to bring the disk back online. 2. If the disk status remains Offline, check the cables and disk controller and make sure that the physical disk is healthy. Correct any problems, and try to reactivate the disk again. If the disk reactivation succeeds, any volumes on the disk automatically return to the Healthy status.

created in the same way as shown in Figure 8-2. Don t worry about establishing the relationships, because you ll create those in the following exercises. Between each table creation, save your new table immediately, and make sure it appears in Database Explorer. Then close the table in the designer surface as shown earlier in step 8 of this section.

Part V:

Online (Errors)

The Online (Errors) status indicates that I/O errors have been detected on a region of the disk. A warning icon appears on the disk with errors. Only dynamic disks display the Online (Errors) status. If the I/O errors are transient, reactivate the disk by right-clicking the disk and then clicking Reactivate Disk to return the disk to the Online status.

you for appropriate information, such as a phone number for a modem connection or whether to automatically dial a VPN connection. Supply the requested information and click Next. For more detailed information about completing this wizard, see Creating New Internet Connections on page 103, and Creating a Connection to a VPN Server on page 515.

The Unreadable status occurs when the disk is not accessible for the following reasons:

The disk is spinning up. The disk might have experienced hardware failure, corruption, or I/O errors. The disk s copy of the dynamic disk database might be corrupted.

3 Click Finish. If additional settings need to be configured, the appropriate Settings dialog box for the new connection will appear. Enter the settings and click OK.

An error icon appears on disks that display the Unreadable status. Both dynamic and basic disks display the Unreadable status. Disks might display the Unreadable status while they are spinning up or when Disk Management is rescanning all the disks on the system. In some cases, an unreadable disk has failed and is not recoverable. For dynamic disks, the Unreadable status usually results from corruption or I/O errors on part of the disk, rather than failure of the entire disk. You can rescan the disks (by using the Rescan Disks command on the Action menu in Disk Management) or restart the computer to see whether the disk status changes.

The following status descriptions appear if Disk Management detects a problem with dynamic volumes or if Disk Management does not recognize volumes, such as those created by nonWindows-brand operating systems.

The Failed status occurs when the dynamic disk is damaged or the file system is corrupted. Unless you can repair the disk or file system, the Failed status might indicate data loss. To troubleshoot a volume with the Failed status, make sure that the underlying physical disk is turned on, plugged in, and attached to the computer. Try returning the disk to the Online status by using the Reactivate Disk command. If this procedure succeeds, the volume automatically restarts and returns to the Healthy status. If the disk returns to the Online status but the volume does not return to the Healthy status, you can reactivate the volume manually by using the Reactivate Volume command.

As is shown in Figure 6-1 on page 138, once the dial-up or VPN connections are created, they appear in the box on the Connections tab. If you have more than one dial-up or VPN connection, you need to choose one as your default connection by selecting it and clicking Set Default. Then make one of the following three choices for the default connection:

28:

In some situations, the Failed status does not indicate data loss even though the Reactivate Disk and Reactivate Volume commands fail. These situations occur when:

Whenever you click a column name in Database Explorer, you ll see the properties listed in the Properties window. This is the same Properties window you ve been using, with one minor difference: it is a read-only view and therefore does not let you modify information.
