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. They are not available in search results.
Explore your data center using APTARE StorageConsole customizable report templates or by using parts of your IT infrastructure as entry points. Use Search to find reports, templates and dashboards across the portal.
Use the Reports tab to examine the APTARE StorageConsole catalog of templates, dashboards and reports - 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.

LUN #
The LUN number
RAID Type
SVC RAID Type: Striped, Mirrored
Cluster
2-8 nodes comprise a cluster; 2 nodes comprise an I/O group
MDisk Group ID
The name of the MDisk group
Capacity
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
Mirrored
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
Host
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
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
