Host Utilization Detail
Detail reports are related to a specific enterprise object, such as a backup job or SAN fabric. You can only access detail reports through a link presented in the context of a main report, providing additional information that augments the main report. Detail reports cannot be generated, customized, or saved, as they are specific to the report from which they were derived. Therefore, they will not be available in search results.
Use Quick search to find the main template, report or a dashboard by name. Search is case insensitive, supports partial entries, and will display a list of potential matches.
As you enter the template, dashboard or report name in the Quick Search field, up to 10 potential matches are displayed. If the result is shown, you can select and run it directly from the match list. You can also select All Items to display the full search results page and further filter your results.
You can use the Explorer tab to browse through the StorageConsole templates, dashboards and reports. The navigation pane displays templates organized by products along with user created, and system folders. The main report is located here:
Click a Host Name link or # of Volumes at Risk link.
In addition, this report can be accessed from several other reports via drill-down links, as shown in the following table:

Volume Group
The volume group and logical volume names. For Oracle ASM, this is the ASM Disk Group name.
Capacity
The host’s filesystem storage capacity, as collected by Host Resources data collection. For mounted filesystems, this is the same as dir or df -k. This capacity value is always from the host’s perspective.
Used
The amount of the host’s storage that is currently in use.
% Available
The percentage of the capacity that is unused.
90 Days Min Used
Use these three columns in combination to substantiate the need for additional storage. Using 90 days worth of data, this provides a realistic snapshot of how the forecast was derived. These statistics are available after 90 days of data collection.
90 Days Avg Used
The average 90-day usage. Using 90 days worth of data, this provides a realistic snapshot of how the forecast was derived. These statistics are available after 90 days of data collection.
90 Days Max Used
The maximum usage for the past 90-day period. These statistics are available after 90 days of data collection.
Network Attached Storage Shares
This Network Attached Storage (NAS) Shares table provides details similar to the mount point table, without the Volume Group column.
Mount Point
Mount point of the filesystem.
Raw Filesystem
Filesystem name
Capacity
The host’s filesystem storage capacity.
Used
The amount of the host’s storage that is currently in use.
% Available
The percentage of the capacity that is unused.
90 Days Min Used
Use these three columns in combination to substantiate the need for additional storage. Using 90 days worth of data, this provides a realistic snapshot of how the forecast was derived. These statistics are available after 90 days of data collection.
90 Days Avg Used
The average 90-day usage. Using 90 days worth of data, this provides a realistic snapshot of how the forecast was derived. These statistics are available after 90 days of data collection.
90 Days Max Used

Allocated and Unused LUNs
Use this table to identify LUN storage that may be able to be reclaimed. This table shows any LUNs that have not been partitioned or allocated to a volume group. Therefore, they are not associated with a mount point or file system. This list will be displayed for LUNs that match this “allocated but unused” criteria.
Name
LUN name.
RAID Type
The RAID type of the LUN.
Storage Array
The storage array of the LUN links to the Array Capacity and Utilization.
Array Group
The Array Group for the LUN.
Product
Array product identifier.
Capacity
Capacity of the LUN.
Host
Links to the Host Utilization Detail.
Disks Details
This table lists the disks associated with the host’s utilization. Expand the Disk Details (click on the arrow) to view the raw disk paths, storage types, and LUNs associated with disks.
Multi-pathed disks also are represented in this list. Multi-pathing is supported for the following products: EMC PowerPath, Hitachi Dynamic Link Manager (HDLM), and Symantec Dynamic Multi Pathing (DMP).
Disk Name
Disk name.
Disk Make
The vendor information.
Storage Type
DAS, SAN, NAS.
Storage Array
The Array Group for the disk links to the Array Capacity and Utilization. If the disk maps to a storage array, it is a SAN storage type (by WWN).
LUN
Indicates the LUN to which the disk is mapped, as seen by the host; links to the LUN Utilization Summary.
Size
Disk size, as derived from Host Resources data collection.
Raw Disk Path
Disk path. For DAS or SAN, when the disk does not map to a storage array, the raw disk path is used.
Aliases
Aliases for the disk.
Disk Partitions/Volume Group Details
Expand the Volume Group Details (click on the arrow) to identify unallocated space in a Volume Group and logical volumes that are not being used by hosts. These details highlight inefficient use of storage.
This table will be present only when there are one or more volume groups set up on the selected host. The table displays each volume group along with the physical disks that have been allocated to the volume group and the logical volume details. Use this table to find any un-allocated storage—that is, space that is available within the volume group that has not been assigned to a logical volume.
If the Array name is missing from a table entry it is because it is a local disk.
Oracle Containers include storage pools that are represented in the Volume Group column of this table. The corresponding Disk Capacity column displays the virtual disk capacity allocated to the Zone.
Note: Totals in a Volume Group reflect usable capacity—so, for example, RAID 1 mirrored disks will show only the capacity that is usable.
Volume Group
The name of the volume group.
Type
LUN or DSK.
Name
LUN or Disk name.
Array
Storage array; if this field is empty, it means it is a local disk (DAS).
Physical Disk Name
Name of the disk.
Partition Name
The disk partitions that are part of the volume group.
Size
Disk capacity, derived from Host Resources data collection. This is the same as the value returned from df -k.
VVM Disk Capacity
Volume manager disk capacity.
RAID Type
Disk or virtual disk RAID type associated with the storage pool.
Disk Name
Name of the disk or virtual disk.
Array
Array where the disk and LUN reside.
Disk Capacity
Capacity that has been allocated. In the case of Oracle containers, this is the capacity allocated to the zones.
Zone
Oracle VM (OS instance)
Volume
If the volume value is blank, the Used value represents the data set used capacity. If there is a value listed for the volume, this means it is for a file system.
Used
Represents the capacity “written to” the file system.
Logical Volume
Logical volume name. If listed as Un-allocated, it is not mounted.
Size
Usable volume space.
Physical Size
Physical size of logical member.
NOTE: The Capacity and Used columns are aggregated and then converted to the units selected in the Advanced option of the report from which the Host Utilization Detail was launched. Note that in the conversion to the displayed units, the totals may appear to be slightly inaccurate. This is due to the division or multiplication by 1024.
Host Groups
Displays the host groups for which the host is a member.
Member of the Following Groups
The full pathname of the host group links to additional host group details.
Member Since
Indicates when this host became a member of the group.
Added By
The user who added the host to the group.
Host Utilization Detail (ASM Example)
APTARE StorageConsole Reveals:
• ASM Storage Usage that the Filesystem Does Not Report: Oracle ASM does not use a mount-point for storage usage. Since this storage is managed by Oracle ASM, it is unknown to the filesystem.
• LUN-to-Host Perspective: The number of LUNs used for the ASM instance on the host provides a complete picture of storage usage. Without the exposure that StorageConsole offers, the number of allocated/used LUNs would be smaller—that is, your view of storage usage would be incomplete without the inclusion of ASM usage.
• Mapping of ASM Volume to Storage Tier: By exposing the Array storage used for Oracle ASM instances, capacity and chargeback numbers become more comprehensive and accurate.
Along with traditional filesystem usage, the APTARE StorageConsole Host Utilization Detail report incorporates ASM Disk Group usage. In the above example, the first three rows of the Volume table display ASM Disk Groups. This Host Utilization Detail report provides additional physical disk details, raw disk paths, and aliases (see example below).
This Host-centric view provides:
• Mapping of disk paths to storage array LUNs
• View of shared storage details
