Storage Subsystem Views - By Storage Subsystem

Use this report to view the relationships between the storage subsystems and the computers and filesystems/logical volumes in your environment.

To generate a report for the relationship you want to view, select an item from the Relate Storage Subsystems to: field on the Selection tab. The Selection tab appears when you left-click the Reporting --> Storage Subsystems --> Storage Subsystems Views --> By Storage Subsystem node. For more information about this tab, see Selecting an Object.

The following section describes the fields that appear on the report based on the options selected on the Selection tab.

Computer

The following fields appear on the By Storage Subsystem report if you selected Computers from the Relate Storage Subsystems to: field on the Selection tab. Use this report to view the computers that are using space in storage subsystems.

Field Name

Description

Storage Subsystem

name/alias of a storage subsystem or IBM SAN Volume Controller cluster

Storage Subsystem Type

type of storage subsystem, such as IBM ESS

Computer

name of a computer using storage on a storage subsystem or IBM SAN Volume Controller

Physical Allocation

total amount of disk space consumed (overhead + capacity)

LUN Capacity

storage capacity of all LUNs visible to (surfaced on) each reported computer

Allocated LUN Space

storage capacity of a LUN minus a LUNs unallocated space

Unallocated LUN Space

LUN capacity assigned to each computer minus the space that has been allocated to a logical volume

Filesystems/Logical Volumes

The following fields appear on the By Storage Subsystem report if you selected Filesystems/Logical Volumes from the Relate Storage Subsystems to: field on the Selection tab. Use this report to view the filesystems/logical volumes that are consuming space on storage subsystem disks.

Field Name

Description

Storage Subsystem

name/alias of a storage subsystem hosting a filesystem/logical volume or the associated or IBM SAN Volume Controller

Storage Subsystem Type

type of storage subsystem, such as IBM ESS

Computer

name of a computer using space on a storage subsystem or IBM SAN Volume Controller

Filesystem or Logical Volume Path

name or path of a filesystem/logical volume using space on a storage subsystem or IBM SAN Volume Controller

Capacity

total usable storage capacity of a filesystem or logical volume

Freespace

amount of storage space available on a filesystem or logical volume
