Capacity Reporting - Disk Capacity

Disk Capacity reports allow you to report on, and chart disk capacity, per disk, per computer, per cluster, per computer group, per domain or for the whole network.

By Disk

Field Name

Description

Computer

name of the computer on which a disk resides

Path

name of a disk

Capacity

total storage capacity for a disk

Unallocated Space

amount of unused storage space on a disk (not in filesystems seen by this operating system)

In Storage Subsystem

indicates whether a disk is part of a storage subsystem

Manufacturer

name of the manufacturer of a disk

Model

model number of a disk

Serial Number

serial number of a disk

Primary Defects

number of defects on the disk when it was new

Grown Defects

number of defects detected on the disk since it was new

By Storage Subsystem

Field Name

Description

Name

name/alias of a storage subsystem containing the disk or the IBM SAN Volume Controller managing the disk

Number of Disks

Total number of disks in the storage subsystem

Disk Capacity

Total raw (unformatted) disk capacity of the storage subsystem

Disk Freespace

Total unformatted disk freespace of the storage subsystem

Number of LUNs

Total number of LUNs in the storage subsystem

LUN Capacity

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

Assigned LUN Capacity

Capacity of all LUNs visible to ITSRM agents

Unassigned LUN Capacity

Usable LUN capacity minus assigned LUN capacity

Overhead

Amount of capacity that is dedicated to redundancy

Volume Space Capacity

Total capacity of all formatted volume spaces

Volume Space Free Space

Total freespace of all formatted volume spaces

Volume Space Overhead

Total volume space capacity that is dedicated to redundancy

Unformatted Disk Group Capacity

For ESS, this is the total raw capacity of any unformatted disk groups

Cache

Amount of cache memory internal to the storage subsystem

Manufacturer

Name of the manufacturer of a disk

Model

Model number of a disk

Serial Number

Serial number of a disk

Firmware Revision

Microcode (OS) version

By Cluster

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 IBM Tivoli Storage Resource 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.

By Computer

Field Name

Description

Computer

name of a computer

Total Capacity

total storage capacity for a computer

Total Unallocated Space

amount of unused storage space on a computer (not in filesystems seen by this operating system)

Owned Capacity

total storage capacity for a computer that is owned by that computer. If IBM Tivoli Storage Resource 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 computer. This column does not display the total unallocated disk space on disks not owned by the computer.

OS Type

operating system running on a computer

Network Address

network address of a computer

IP Address

IP address of a computer

Time Zone

time zone in which a computer is running

By Computer Group

Field Name

Description

Creator

creator of a computer group

Group

name of a computer group

Total Capacity

total storage capacity for the computers in a computer group

Total Unallocated Space

amount of unused storage space on the computers in a computer group (not in filesystems seen by this operating system)

Owned Capacity

total storage capacity for a computer that is owned by that computer. If IBM Tivoli Storage Resource 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 computer group. This column does not display the total unallocated disk space on disks not owned by the computers

By Domain

Field Name

Description

Domain

name of a domain

Capacity

total storage capacity for the disks in a domain

Unallocated Space

amount of unused storage space on the computers in a domain (not in filesystems seen by this operating system)

Network-wide

Field Name

Description

Capacity

total storage capacity for the computers on a network

Filesystem Used Space

amount of storage space consumed on the filesystems on a network

Filesystem Free Space

amount of storage space available on the filesystems on a network

Raw Volume Space

capacity of logical volumes that do not contain filesystems

Overhead

amount of storage space for RAID or mirror redundancy

Unallocated Space

amount of unused storage space on a computer (not in filesystems seen by this operating system)

Unknown LUN Capacity

sum of LUN capacity for LUNs whose use (by agent-computers) is not known
