HPE StoreOnce backups fail

If your backups fail, one of the reasons could be related to HPE StoreOnce sizing parameters. In this case, check the following:

  • If you have defined a Physical or Logical Storage Quota for your Catalyst store, check if the quota limits have been reached. If so, increase the quota to a sufficient size. For details, see HPE StoreOnce Configuration.
  • If you created an HPE Catalyst data store in SEP sesam and later changed the HPE Catalyst store size parameters, e.g., by changing or removing the storage quotas, check their values in SEP sesam GUI: Main selection -> Components -> Data Stores, double-click your StoreOnce store, and then click the HPE Catalyst Store State tab. If the data store status is set to "failed", you may need to adjust the StoreOnce data store (Size) Capacity and High watermark values to allow for correct calculation and make the data store functional again. For details, see Size and Disk space usage.

HPE StoreOnce backup failed with "553 STOR Failed. Error: Ctl_OpenObject failed, error: OSCLT_ERR_MAXIMUM_SESSIONS. (0)

Problem

  • HPE StoreOnce backup failed with 553 STOR Failed. Error: Ctl_OpenObject failed, error: OSCLT_ERR_MAXIMUM_SESSIONS. This issue can occur when an HPE StoreOnce Catalyst data session fails to open because the maximum number of sessions on the HPE StoreOnce Catalyst server is reached, thus no other session can be started until resources are available. You can check the number of free data sessions in SEP sesam by opening your HPE StoreOnce data store properties and clicking the tab HPE Catalyst Store State, then checking the value of Free data sessions.

Solution

There are two possible solutions:

  • The HPE Catalyst server supports a limited number of concurrent data sessions. Therefore, you need to ensure that the maximum number of data sessions for your HPE StoreOnce is not exceeded, or increase the maximum number of data sessions (including restores) that can be run simultaneously.
  • Open SEP sesam and from the Main selection -> Components -> Data Stores double-click your HPE StoreOnce data store to open the properties. Then, under Drives click the relevant drive to view its properties. In the Max. channels drop-down list, decrease the number of available channels for concurrently running backup/migration streams. By default, the number of available channels is set according to your SEP sesam Server license (e.g., the standard license supports 10 concurrent streams, enabling 10 backup processes to run simultaneously).
