HPE StoreOnce Catalyst

Backup

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 the 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:

  • HPE Catalyst server supports a limited number of concurrent data sessions, therefore you have 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 run concurrently.
  • Open SEP sesam and from the Main selection -> Components -> Data Stores, double-click click your HPE StoreOnce data store to open the properties, then under the Drives click the relevant drive to display its properties. From the Max. channels drop-down list, reduce 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).
