Asset Reporting - By Storage Subsystem

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:

Note: Some of these reports will contain inaccurate information if the following configuration is used:

In this situation, Disks and LUNs will appear to belong to both the IBM SAN Volume Controller and the ESS subsystem, and will be counted twice in system-wide reports. To avoid this situation, CIM/OM access should be set up for only one of these resources.

Storage Subsystems

When you select the name of a storage subsystem, you can view the following information about that storage subsystem in the content pane:

Field Name

Description

Group

name of the IBM Tivoli Storage Resource Manager group to which a storage subsystem belongs

Manufacturer

name of the manufacturer of the storage subsystem

Model

number of the storage subsystem model

Serial Number

serial number of the storage subsystem

Cache

storage size of the storage subsystem cache

Non-volatile Storage

type of cache/memory used to protect the integrity of your data in case of disaster (for example, power failure)

Firmware Revision

microcode or operating system version

Number of Disks

number of disks associated with the storage subsystem

Disk Capacity

amount of storage space allocated to the disks associated with the storage subsystem

Disk Free Space

amount of storage space available on the disks associated with the storage subsystem

Volume Space Capacity

total amount of storage space in the volume spaces associated with the storage subsystem

Volume Space Freespace

amount of storage space available to allocate LUNs in the volume spaces associated with the storage subsystem

Volume Space Overhead

sum of all the space in a disk group minus the volume space capacity

Unformatted Disk Group Capacity

amount of disk capacity that is available for creating volume spaces

Number of LUNs

number of LUNs associated with the storage subsystem

LUN Capacity

amount of storage space allocated to the LUNs associated with the storage subsystem

Last Probe Time

date/time when the storage subsystem was last probed

Last Probe Status

indicates the success or failure of the last probe

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

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:

Volume Spaces

When you expand the Volume Spaces node, the Reporting facility displays a list of volume spaces for the storage subsystem. You can expand the name of a volume space to view the disks and LUNs within that volume space.

Drill down through both the Disks and LUNs subnodes to view:

Disks

When you expand the Disks node, the Reporting facility displays a list of disks for the storage subsystem. You can expand the name of disk to view the LUNs associated with that disk.  

Click the name of a LUN associated with a disk to view detailed information about that LUN. To learn about the windows containing information on LUNs, click any of the following links:

LUNs

When you expand the LUNs node, the Reporting facility displays a list of LUNs for the storage subsystem. Click the name of a LUN to view detailed information about that LUN. To learn about the windows containing information on LUNs, click any of the following links:

IBM SAN Volume Controller clusters

When you select the name of an IBM SAN Volume Controller cluster under the Storage Subsystem node, you can view the following information in the content pane:

Field Name

Description

Group

name of the resource group to which the IBM SAN Volume Controller cluster belongs

Manufacturer

the name of the manufacturer

Model

the model number

Required Memory

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

Managed Disk Capacity

total capacity of the disks associated with the cluster

Managed Disk Free Space

amount of storage space available on the disks associated with the cluster

Managed Disk Group Capacity

total capacity of disks associated with the cluster that have been grouped

Managed Disk Group Free Space

amount of storage space available in the disks associated with the cluster that have been grouped and can be used by a virtual disk

Number of Virtual Disks

the number of virtual disks associated with the cluster

Virtual Disk Capacity

amount of virtual disk capacity that is available for creating volume spaces

Last Probe Time

date/time when the cluster was last probed

Last Probe Status

indicates the success or failure of the last probe

Probing Agent

the name of the IBM Tivoli Storage Resource Manager agent that ran the probe job to collect the report information

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

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.

Drill down through both Managed Disks and Virtual Disks to view:

Managed Disks

When you expand the Managed Disks node, the Reporting facility displays a list of disks managed by the IBM SAN Volume Controller cluster. You can expand the name of a disk to view the virtual disks associated with it.

Drill down through both Managed Disks and Virtual Disks to view:

Virtual Disks

When you expand the Virtual Disks node, the Reporting facility displays a list of the logical disks the cluster provides to the SAN.

Click the name of a disk to view detailed information about it. To learn about the windows containing information on virtual disks, click any of the following links:
