10-25Lesson 1 Managing and Troubleshooting Disks and Volumes
Media libraries Encompass both online libraries and offline media physical loca-
tions. Online libraries, which include robotic libraries and stand-alone drives, are
data-storage devices that provide a method of reading and writing to media when
necessary. Offline media physical locations are holding places for media units that
are cataloged by Removable Storage, but are not currently immediately available
through an online library.
Work queues Hold library requests until resources become available. For example, a
robotic tape library has a fixed number of tape drives to access media. A request
submitted to the library is held in a work queue until a tape drive becomes avail-
able and the requested tape is mounted.
Operator (administrator) requests Hold requests for offline media. The operator
must make the media available before processing can continue. Other situations
that generate operator requests include the failure of a device or a device needing
to be cleaned when no cleaner cartridge is available. After a request is satisfied,
the administrator must inform Removable Storage so that processing can continue.
Note Removable storage devices can contain primary partitions only, and those partitions
cannot be marked as active.
The Removable Storage Utility
You perform initial installation, configuration, and troubleshooting of removable stor-
age devices by using the Add Hardware Wizard and Device Manager. After being rec-
ognized by the operating system, removable storage devices are available for
management through the Removable Storage utility. Access Removable Storage by
expanding the Storage node in the Computer Management window.
By using the Removable Storage utility, you can insert and eject removable media, con-
trol access to media, and manage the use of media by applications. Systems with stan-
dard, stand-alone, removable devices (such as a CD-ROM or DVD-ROM drive, Zip
drive, or tape drive) do not require management and configuration by using Remov-
able Storage. Removable Storage is required for computers with more complex config-
urations, which can include tape or optical disk libraries, especially if multiple
applications will access those devices. You should always consult the documentation
for the removable device to determine how it is best managed.
See Also Removable Storage devices that require management through the Remote Stor-
age utility are most likely attached to Windows servers in a network environment. Further dis-
cussion of Removable Storage management is beyond the scope of this text. For more
information, see https://traloihay.net and search for “Removable Storage.”
Practice: Managing Hard Disks
In this practice, you will check the status of existing volumes on your computer by
using Disk Management and also change the drive letter for a volume.
