Displays the amount of free disk space available on the HMC. When you add a local installation resource to the HMC, the amount of available disk space decreases based on the size of the new installation resource. When you remove a local installation resource, the amount of disk space increases based on the size of the deleted installation resource.
The HMC must have a minimum of 3GB of free hard disk space on the local hard drive. If the value for this field indicates that the amount of available space is below this minimum, the Add button is unavailable and you cannot define and add a local installation resource.
Note: The HMC must have enough free hard disk space for the necessary set of operating environment installation files. The HMC creates the installation resource in the same local hard drive location that the HMC uses for main store dumps. Consequently, it is recommended that you maintain a certain amount of free hard drive space to avoid potential main store dump problems because main store dumps are necessary to help resolve some types of HMC errors. The typical main store dump averages between 4 to 8 gigabytes (GB), so consider maintaining at least 10 GB of free hard drive space for these dumps when you define and create local installation resources for the HMC.
