Drill down through your storage subsystem assets in a hierarchical manner. IBM Tivoli Storage Resource Manager provides reporting for individual storage subsystems as well as IBM SAN Volume Controller clusters.
For storage subsystems, you can view information about:
Disk Groups (for ESS subsystems)
Volume Spaces (for ESS subsystems)
Disks (for ESS subsystems)
LUNs (for ESS subsystems)
Managed Disk Groups (for IBM SAN Volume Controllers)
Managed Disks (for IBM SAN Volume Controllers)
Virtual Disks (for IBM SAN Volume Controllers)

You can expand the name of a storage subsystem and view subnodes for its associated disk groups, volume spaces, disks, and LUNs. Drill down further on the:
Disk Groups node to view the volume spaces and disk groups. Within a volume space, you can drill down to view the disks and LUNs within that volume space.
Volume Spaces node to view the disks and LUNs within those volume spaces
Disks node to view: 1) the disks associated with the storage subsystem, 2) the LUNs with segments on those disks, 3) information about those disks
LUNs node to view: 1) the LUNs associated with the storage subsystem, 2) the disks containing segments from those LUNs, 3) information about those LUNs
When you expand the Disk Group node, the Reporting facility displays a list of disk groups for the storage subsystem. You can expand the name of a disk group to view the disks and volume spaces within that disk group.
Drill down through both Volume Spaces and Disks subnodes to view:
the disks and LUNs associated with a volume space
the LUNs with segments on a disk
the disks containing segments from a LUN
detailed information about a disk. To learn about the windows containing information on Disks, click any of the following links:

the amount of memory required for the cluster |
Code Level |
the microcode version |
Number of Managed Disks |
number of disks associated with the cluster |
Number of Managed Disks Assigned to a Group |
the number of disks associated with the cluster that have been grouped |

You can expand the name of a cluster and view subnodes for its managed disk groups, managed disks, and virtual disks. Drill down further on the:
Managed Disk Groups node to view the groups of managed disks. Within a disk group, you can drill down to view the managed disks and virtual disks associated with that group.
Managed Disks node to view the disks available to the cluster. For each disk, you can drill down to view the virtual disks associated with it.
Virtual Disks node to view the logical disks the cluster makes available to the SAN.
When you expand the Managed Disk Group node, the Reporting facility displays a list of disk groups managed by the IBM SAN Volume Controller cluster. You can expand the name of a disk group to view its physical disks and virtual disks.
