This appendix describes the icons used in MSU for the following devices:
Array | Events | Physical Disk | Virtual Disk | Other Devices
Table 1 lists the icons used to indicate the status of arrays.
Symbol |
Description |
Notes |
|
Online Array
|
The array is operating normally. |
|
Degraded Array
|
The array is degraded and has no fault tolerance. In this state, data is not recoverable if even one physical disk fails. Rebuild the array by replacing the failed physical disk(s). |
Table 2 lists the icons used for adapter events.

Normal Event
|
Example: Physical disk 1 is assigned as spare. |
|
Unknown Event
|
Any event that was not recognized by MSU. See Windows Events Viewer for more information on the event. |
|
Warning Event
|
Example: Virtual Disk 1 is deleted. |
|
Critical Event
|
Example: Virtual Disk 1 is degraded. |
Table 3 lists the icons used to indicate the status of physical disks.

Notes |
|
Unconfigured Physical Disk
|
The physical disk is available for use in a virtual disk (or array). |
|
Configured Physical Disk
|
The physical disk is part of a virtual disk. |
|
Foreign Physical Disk |
The foreign physical disk is part of a virtual disk created with another RAID controller. The foreign physical disk cannot be used on the RAID controller unless the RAID configuration metadata is erased on the disk. |
|
Offline Physical Disk
|
The physical disk is part of a virtual disk and has an error. Check the event log for details and replace the physical disk if necessary. Note: An offline physical disk can render a virtual disk offline or degrade it. |
|
Unconfigured Spare Drive
|
The spare drive is available for rebuilding virtual disks and arrays. |
|
Configured Spare Drive
|
The spare drive was used to rebuild a virtual disk and is now part of the same. |

Table 4 lists the icons used to indicate the status of virtual disks.
Symbol |
Description |
Notes |
|
Online Virtual Disk
|
The virtual disk is operating normally. |
|
Online Virtual Disk with Background Activity |
The virtual disk is operating normally and performing a background activity. |
|
Offline Virtual Disk
|
This virtual disk is not operating because one or more member physical disks are not connected. Data can neither be written nor read from the virtual disk. |
|
Foreign Virtual Disk
|
The RAID configuration metadata on the physical disk indicates that it is part of a virtual disk that was created with another RAID controller. |
|
Partially Optimal Virtual Disk
|
One or more physical disks in the virtual disk have failed and reduced the fault tolerance of the virtual disk. The virtual disk is still operating normally. |
|
Partially Optimal Virtual Disk with Background Activity |
The partially optimal virtual disk is performing a background activity. |
|
Degraded Virtual Disk
|
The virtual disk is degraded and has no fault tolerance. In this state, data is not recoverable if even one physical disk fails. Rebuild the virtual disk by replacing the failed physical disk(s). |
|
Degraded Virtual Disk with Background Activity |
The degraded virtual disk is rebuilding. |
