HMC Disk Space Test

This test monitors the space usage of each disk partitions on the HMC server, and points you to those disk partitions that are critically low on space.

Target of the test : An IBM HMC server

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each disk partition on the HMC server.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.


The host for which the test is to be configured.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Total capacity

Indicates the total capacity of this disk partition.



Used space

Indicates the space used on this disk partition.



Free space

Indicates the amount of unused space on this disk partition.



Percent usage

Indicates the percentage of space on this disk partition that is in use.


Ideally, the value of this measure should be low. A high value is indicative of excessive space usage on the disk partition. If the value is dangerously close to 100%, it indicates that the partition will soon run out of space. You may want to clear some space on the disk partition, so that you can continue working with the HMC server
