IBM SVC VDisk Summary
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:
Then, select IBM SVC arrays for the report scope.
Then, click on # VDisks or # VDisks Allocated to Hosts.
The following view is available when only IBM SVC arrays are selected for the report scope. In addition, several related reports narrow the list of LUNs in the report:
IBM SVC VDisk Summary - Unallocated: Access this report from the Array Capacity & Utilization report by clicking on #VDisks Unallocated.
IBM SVC VDisk Summary - Allocated: Access this report from the Array Capacity & Utilization report by clicking on #VDisks Allocated to Hosts.
To display IBM SVC LUNs, along with LUNs from other storage vendors, see the LUN Utilization Summary.

The LUN number
SVC RAID Type: Striped, Mirrored
2-8 nodes comprise a cluster; 2 nodes comprise an I/O group
MDisk Group ID
The name of the MDisk group
Total VDisk (LUN) capacity
Copy Capacity
Copy capacity includes mirrors
Real Capacity
Allocated VDisk capacity; the capacity that is available to hosts
Used Capacity
Amount of the allocated VDisk capacity (real capacity) that is used
Free Capacity
Free = Capacity - Real Capacity
Indicates if this LUN has a mirror
Space Efficient
Indicates if this is a thin-provisioned LUN
IO Group Name
The name of the I/O group to which this VDisk belongs
Estimated Used
From the host’s perspective, the amount of storage used
Estimated Available
From the host’s perspective, the amount of available storage
Hosts that have storage allocated from this LUN
Host LUN
The name of the host to which storage from this LUN was allocated. Click on a host link to launch the Host Utilization Detail.
Mount Point
Mount point of the filesystem
The host’s filesystem or drive name to which the LUN maps. LUNs simply appear as disks to hosts.
Volume Group
Volume group using storage from this LUN
Host Storage Domain
A logical group of LUNs that can be accessed by multiple hosts through the same physical storage port, with each host accessing its unique LUN. For security purposes, LUN masking is also coupled with this capability. For Hitachi arrays, this is the multi‑hosted storage capability.
Array Port WWN
The array port world-wide name
