• HSM status and process ID
• Capacity, used, and free space
• Volume Parameters for disk space monitoring
•Watermarks
• Retention times
• Exclusion list
• Scheduling for the file policy process
• File Policy definitions

Disk space monitoring
For each managed volume a disk space monitor is running, which regularly checks the disk space
utilization and frees up space on the managed volume, when the high or critical watermark level is
reached. This release process continues until the low watermark level is met or until no more file candidates
for releasing are available.
When the disk utilization reaches the critical watermark, all files that are already copied to secondary
storage (cached files) are candidates for releasing. In this case the retention time criteria are ignored.
