Came across this setting and was wondering when this should be used? What is a possible usecase to tweak this setting? 

 

Configure Disk Volume Size

Disk volumes are created based on the volume size. When the size of the volume reaches the maximum size, then a new volume is created. The maximum size of a disk volume is set to 25 GB by default, and this value can be modified.

  1. On the ribbon in the CommCell Console, click the Storage tab, and then click Media Management.

  2. Click the Resource Manager Configuration tab.

  3. Modify the Disk volume physical size high watermark in GB parameter as required.

  4. From the Disk volume physical size high watermark in GB box, enter the disk volume size.

  5. Click OK.

It’s there was an option in case a specific library vendor has any recommendations, though I don’t expect it gets used much by the average person.
