The Logical Disk % Free Space monitor enables Operators to set varying threshold values for system and non-system logical disk volumes. In addition separate threshold values can be set for Warning and Error states.
When existing files grow in size and the new files are added, the free space is taken up on a logical disk. When the amount of free space on the logical disk falls below the threshold, the state for the logical disk will change.
To increase the amount of available disk space, do one or more of the following:
Run Disk Cleanup to gain more free space on the disk.
Back up and remove files, or delete unnecessary files from the disk.
Move files to another disk or to offline storage.
Purchase additional storage or switch to a larger disk.
