Pool Scrubber parameters

This page describes parameters of the pool scrubber operation. The Pool Scrubber Parameters window displays settings used by the Daily VOB Pool Scrubbing scheduled job. This job reclaims space in derived object and cleartext storage pools by deleting data containers in those pools. It does not affect source storage pools.

You can specify the following parameters to constrain pool scrubbing:

Maximum size
No scrubbing takes place unless the pool is at least this size.
Reclaim size
Scrubbing stops when the pool falls below this size. However, if Maximum size is 0, this parameter is ignored.
Age
Data containers are deleted only if they have not been accessed for at least this number of hours. Containers least recently accessed are deleted first. A derived object container is deleted only if the reference count for the derived object is 0, indicating that the derived object is not used in any view. In this case, the derived object is deleted from the VOB database as well.
Alert command
You can specify an alert command. This causes the scrubber to run the specified command (typically, a batch file) whenever it fails to scrub a pool below its max-kbytes level. If you use a command built into the Windows shell (for example, cd, del, dir, or copy) instead of a batch file, you must open the shell with cmd /c. For example:
-alert 'cmd /c cd \tmp & del *.*'

Click Default to restore any of these parameters to its default value.
