Modify the Data Store Threshold

A data store has default threshold setup in the system and physical memory. To free up space or replace the existing disk with a bigger disk, you can modify the default threshold manually. In a deduplication data store, the threshold monitors the memory allocated to the hash destination and the disk space allocated for the backup destination folder, index destination, and data destination. For a nondeduplication data store, the threshold monitors the storage space only of the backup destination folder. All the five items that the thresholds monitors have two types of values: warning threshold and error threshold.

Thresholds registry locations and default values

1. Registry location: [HKEY_LOCAL_MACHINE\SOFTWARE\CA\ARCserve Unified Data Protection\Engine\DataStore\XXXXXXX\CommStore]

   Threshold values: "WarnPathThreshold"="0.03" and "ErrorPathThreshold"="100"

2. Registry location: [HKEY_LOCAL_MACHINE\SOFTWARE\CA\ARCserve Unified Data Protection\Engine\DataStore\XXXXXXX\GDD\DataRole]

   Threshold values: "WarnPathThreshold"="0.03" and "ErrorPathThreshold"="100"

3. Registry location: [HKEY_LOCAL_MACHINE\SOFTWARE\CA\ARCserve Unified Data Protection\Engine\DataStore\XXXXXXX\GDD\HashRole]

   Threshold values: "WarnPathThreshold"="0.03" and "ErrorPathThreshold"="100", "WarnMemThreshold"="0.03" and "ErrorMemThreshold"="10"

   Note: Hash role monitors the memory and disk usage both. Path represents the disk usage and Mem represents the memory.

4. Registry location: [HKEY_LOCAL_MACHINE\SOFTWARE\CA\ARCserve Unified Data Protection\Engine\DataStore\XXXXXXX\GDD\IndexRole]

   Threshold values: "WarnPathThreshold"="0.03" and "ErrorPathThreshold"="100"

5. For physical memory available in both the system and physical memory allocated to the data store:

   Registry location: [HKEY_LOCAL_MACHINE\SOFTWARE\CA\ARCserve Unified Data Protection\Engine\DataStore\XXXXXXX\GDD\HashRole]

   Threshold values: "WarnMemThreshold"="0.03" and "ErrorMemThreshold"="10"

Follow these steps to modify the threshold:

1. Navigate to the respective registry location.
2. Manually modify the default value of threshold.

   When the data store approaches a threshold, the following warning message is displayed:

   Running Low Disk Space: Data Destination.
   

   

Note: You can view the error and warning messages from the log tab in the Console.

The data store threshold is modified.
