Enable 0 cycle retention on WORM pool

Question

Hello community,

we used a deduplicated WORM cloud storage pool for a while but needed to start fresh because of unexpected growth.

In the process of aging the data of the old pool we noticed an issue because of the default 1 cycle retention which required a workaround to bypass the cycle retention.

Therefore we would like to enable zero cycle retention on the new WORM pool like described here: Configuring WORM Storage Lock

When preparing the pool and assigning the first storage policy to it I noticed that the cycle retention got increased to 1 after enabling WORM despite running the command from the documentation beforehand.

So my question is: Is there more to do than described in the documentation to enable the zero cycle retention on WORM pools or is the GUI just “showing” 1 cycle but using 0 in the background?

I tried reproducing the issue again, but now it seems like the setting was applied correctly.

The only difference as far as I can tell was that I did not have a plan already assigned to the pool before enabling WORM.
When executing the command on an empty pool with no assigned plan copies the cycle retention stays 0 on the pool and on the plan copies added afterwards.

So maybe this should be added to the documentation if my assumption is true.

Hi ​@Marcel_RE,To enable zero cycle retention, you must set the number of cycles to 0 in the storage pool retention settings and the value must be set and saved.How to Set Zero Cycle Retention:Download and usethehttps://documentation.commvault.com/11.40/software/files/features/storage_policies/xml/Update_BasicRetention.xmlscript.Run the following command (replace placeholders with your values):qoperation execute -af &lt;downloaded location&gt;\Update_BasicRetention.xml -storagePolicyName &lt;StoragePoolName&gt; -retainBackupDataForCycles 0 -retainBackupDataForDays &lt;required days retention&gt; -copyName &lt;StoragePoolCopyName&gt;
