Name |
name/alias of a storage subsystem containing the disks or the IBM SAN Volume Controller managing the disks |
|
Disk Capacity |
Total raw (unformatted) disk capacity of the storage subsystem For Hitachi Data Systems storage subsystems, this is the capacity of all the LUNs in the storage subsystem. This capacity does not include the capacity of ESS spare disks. |
|
Disk Unallocated Space |
Total unformatted disk freespace of the storage subsystem For Hitachi Data Systems storage subsystems, internal disk information is not available. This field will be 0. |
|
Number of Disks |
Total number of disks in the storage subsystem For Hitachi Data Systems storage subsystems, internal disk information is not available. This field will be set to 1. |
|
Number of LUNs |
Total number of LUNs in the storage subsystem |
|

Total capacity of all the LUNs in the storage subsystem |
|
Useable LUN Capacity |
Capacity of LUNs created without counting BCVx, VCM database, and replication targets Note: for IBM DSxxxx, HP StorageWorks, and Hitachi Data Systems storage subsystems, the value in this column is the same as the value in the LUN Capacity column. |
|
LUN Capacity Visible to Data Manager |
Capacity of all LUNs visible to Data Manager agents |
|
LUN Capacity not Visible to Data Manager |
Usable LUN capacity minus assigned LUN capacity |
|
Overhead |
Amount of capacity that is dedicated to redundancy |
|
Formatted Capacity |
(IBM ESS, IBM DSxxxx, HP StorageWorks, and Hitachi Data Systems only) total amount of formatted storage space in the storage pools associated with the storage subsystem. For example, a RAID volume space has more capacity than a stripe-mirror volume space. |
|
Formatted Space with No Volumes |
(IBM ESS, IBM DSxxxx, HP StorageWorks, and Hitachi Data Systems only) amount of storage space available to allocate to LUNs in the storage pools associated with the storage subsystem. |
|
Total Overhead |
(IBM ESS only) sum of all the space in a disk group minus the formatted capacity. |
|
Unformatted Disk Group Capacity |
For IBM ESS subsystems, this is the total raw capacity of any unformatted disk groups. For IBM DSxxxx, HP StorageWorks, and Hitachi Data Systems storage subsystems this is the total capacity of the disks that are not in a storage pool. |
|

|
Serial Number |
Serial number of a disk |

|
Subsystem Assigned LUN Capacity |
total storage capacity of all LUNs that the storage subsystem knows are assigned to a host computer. Note: the column will appear blank for San Volume Controller (SVC) |
|
Storage Subsystem Unassigned LUN Capacity |
totals storage capacity of all LUNs that the storage subsystem knows are not assigned to a host computer. Note: the column will appear blank for San Volume Controller (SVC) |
|
Subsystem Total Formatted Free Space |
Storage Subsystem Unassigned LUN Capacity + Formatted Space with No Volumes (i.e., formatted capacity in the storage subsystem that is not allocated to a LUN and is not assigned to a host computer). Note: this column will appear blank for San Volume Controller (SVC). |
|
zOS Lun Capacity |
total storage capacity for all the LUNs allocated to zOS. Data for this column is calculated for ESS only--the value for this column is set to N/A for other storage subsystems. |
|
Open System LUN Capacity |
total LUN storage capacity (excluding the zOS LUN capacity) |
|
Field Name |
Description |
|
Cluster |
name of a cluster |
|
Total Capacity |
total storage capacity for a cluster |
|
Total Unallocated Space |
amount of unused storage space on a cluster (not in filesystems seen by this operating system) |
|
Owned Capacity |
total storage capacity for a computer that is owned by that computer. If Data Manager can determine that a disk was configured for a different host, that disk's capacity will not be counted in the "Owned Capacity". If the host is Solaris and Veritas Volume Manager (VxVM) is in use, the product will examine the Veritas disk-label and read off the host-ID. If this does not agree with the local host-ID, the disk is classified as belonging to a different (Solaris) host. |
|
Owned Unallocated Space |
total unallocated space on disks owned by the computers in a cluster. This column does not display the total unallocated disk space on disks not owned by the computers in a cluster. |

|
Total Capacity |
total storage capacity for a computer. If the computer is an IBM SAN file system client, then this value will also include the capacity of any LUNs visible to this computer that are owned by the SAN file system. |
|
Total Unallocated Space |
amount of unused storage space on a computer (not in filesystems seen by this operating system). If the computer is an IBM SAN file system client, then this value excludes the unallocated space on any LUNs visible to it that are owned by the SAN file system. |
|
Owned Capacity |
