HP Systems Insight Manager 5.3 Technical Reference Guide

• Raw Space configured for a specific purpose.
• Assigned Space that is assigned to pools of storage that can be configured into storage volumes
(LUNs).
• Allocated Space configured as storage volumes, but not connected through ports. An application
cannot access an allocated space until it is assigned to a port.
• Exposed Space configured as storage volumes that is connected through ports. Applications
can access this space.
• RAID Overhead Space on the array that is not directly usable because it is being used to provide
redundancy. For example, if 100 GB is allocated for a RAID 1 (mirrored) storage volume, 50 GB
are directly usable (Allocated or Exposed), and 50 GB is RAID Overhead to provide the mirrored
copy of the data.
• Other Space not accounted for by previously listed categories. Other space is typically used
for metadata.

System tab for a tape library
A tape library is a tape drive connected to a SAN. Additional links are available on the System Page to
access information when a tape library is selected. Included here are areas that are unique to tape libraries.
HP SIM displays data supplied by the tape library's SMI-S provider . If the SMI-S provider does not supply
data for a particular property, the property does not appear on this page. For additional information about
the tab, see “System tab”.
The Ports, Media Access Devices, and Changer Devices sections show the date, time, and duration of
the last data collection task. To update the data, click the Last Update link, and schedule or run a Data
Collection task. For additional information about data collection tasks, see “Data collection”
If this tape library is managed by HP Storage Essentials, the Ports, Media Access Devices, and Changer
Devices sections do not appear on this page, and an SE System Properties link appears in the Storage
Essentials Pages section on the Tools & Links tab. Click the SE System Properties link to view the
Storage Essentials device page for this tape library.
The Quick Launch hyperlink links to a short list of frequently used tools. Place your cursor over the link to
expand the menu and view the tools available for displayed systems. Selecting a tool from this list bypasses
