Commvault as backup application - HP StoreOnce as Media : OSCLT_ERR_NO_DEVICES_DISCOVERED

 Observation: Once I was conducting a full db restore, 1/3 of my db files were restored then all my 6 streams failed due to below error


The error below is sourced from internet to show you the example error, all the error codes are same just the media name will be different

channel ch1: reading from backup piece 61xxxxxxxxxxx
ORA-19870: error reading backup piece 61xxxxxxxxxxx
ORA-19507: failed to retrieve sequential file, handle="61xxxxxxxxxxx", parms=""
ORA-27029: skgfrtrv: sbtrestore returned error
ORA-19511: Error received from media manager layer, error text:
sbtrestore: Job[44240] thread[3696]: CVArchive->open() failed.


What should you do in such error?

Have a call with your backup team, have them display the commvault restore job 44240 log.

If you notice the job failed due to an error in the subject of the blog, then you likely to face a communication error between commvault and storeonce device.

Mostly due to insufficient resources.

In such cases, please restart your restore after informing your backup team to keep an eye on the restore and resource usage in both StoreOnce and Commvault.


Remember StoreOnce has a limit to the number of active streams it can handle, I believe it will be 200 or some number. When that is exceeded we can face communication issue like above.


Thanks
