System Wide - Storage Subsystems

System Wide Storage Subsystem reports provide detailed information about the monitored Storage Subsystems in your environment.

Select beside the Storage Subsystem name for which you want to view detailed information.

You can generate and sort the data within Storage Subsystem reports using the following By Clauses:

Each row in the report gives you information for each Storage Subsystem. The following table describe the fields available through each of the By Clauses:

Field Name

Description

Name

name/alias of storage subsystem

Number of Disks

total number of disks in the storage subsystem

Disk Capacity

total raw disk space in the storage subsystem

Disk Free Space

total raw unused disk space in storage subsystem

Number of LUNs

total number of LUNs defined in storage subsystem

Note: not all are necessarily accessible

LUN Capacity

total LUN capacity of storage subsystem including inaccessible LUNs

Usable LUN Capacity

storage capacity of LUNs in the storage subsystem (not including BCVs, VCM database, and Replication targets). Includes inaccessible LUNs.

Assigned LUN Capacity

storage capacity of LUNs in the array that are visible to computers where IBM Tivoli Storage Resource Manager agents are installed

Unassigned LUN Capacity

usable LUN capacity assigned to each computer minus the assigned LUN capacity

Overhead

storage space used by mirroring or RAID

Volume Space Capacity

(ESS only) total capacity of volume spaces. For example, a RAID volume space has more capacity than a stripe-mirror volume space.

Volume Space Free Space

(ESS only) total capacity in volume spaces which has not been assigned to LUNs.

Volume Space Overhead

(ESS only) raw disk space in defined volume spaces minus volume space capacity.

Unformatted Disk Group Capacity

raw disk space in ranks on which no volume space has been defined

Cache

amount of RAM or other cache for a storage subsystem

Manufacturer

manufacturer of a storage subsystem

Model

model of a storage subsystem

Serial Number

serial number of a storage subsystem

Firmware Revision

microcode level
