Bring an offline dynamic disk back to an imported state
An Offline dynamic disk may be corrupted or intermittently unavailable.
To bring an offline dynamic disk back to an imported state
- Repair any disk or controller problems, and make sure that the disk is turned on, plugged in, and attached to the computer.
- Use the Rescan command to rescan all the devices on the SCSI bus to bring the disk back online.
Select Rescan from the Actions menu, or right-click the StorageAgent node in the tree view to get a context menu and select Rescan from that menu. If you have a lot of devices on the computer's SCSI bus, the rescan of the bus may take some time.
See Rescan command.
If one of the disks has failed and you have a mirrored or RAID-5 volume, the repair involves recreating a part of the volume in a different location.
For more information:
- If the disk does not come back after doing a rescan, select the disk and use the Reactivate Disk command to manually bring the disk back online.
Right-click the disk's label in the tree view or the Disk View tab view to bring up the disk's context menu and select the Reactivate Disk command from the menu.
Dynamic disks belonging to a Microsoft Disk Management Disk Group do not support the Reactivate Disk command.
If reactivating the disk does not change its status, something must be wrong with the disk or its connections.
- If a disk comes back online after reactivating, check to see whether its volumes are healthy. If not, try the Reactivate Volume command on its volumes.
Dynamic disks belonging to a Microsoft Disk Management Disk Group do not support the Reactivate Volume command.
- Run Chkdsk.exe to make sure that the underlying data on the disk is not corrupted.
To run Chkdsk, open a command prompt window and enter the following command:
chkdsk x: /f
where x is the drive letter of the volume you want to check. The /f option tells Chkdsk to fix any errors it finds. If the /f option is omitted, Chkdsk operates in a read-only mode.
Although Chkdsk cleans up the file system structure, there may be invalid data on the disk if users are working when a problem occurred on the disk. It is highly recommended that you run utilities to check the integrity of the data. If the data is corrupted, you need to replace it from backup storage.
