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:
By Storage Subsystem
By Capacity
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 |
