Icons used in MSU

This appendix describes the icons used in MSU for the following devices:

Array | Events | Physical Disk | Virtual Disk | Other Devices

Array

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).

Events

Table 2 lists the icons used for adapter events.

Notes

 

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.

Physical Disk

Table 3 lists the icons used to indicate the status of physical disks.

Description

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.

Virtual Disk

Table 4 lists the icons used to indicate the status of virtual disks.

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.
