(DP) support tip: Cannot open device (StoreOnce error: Client not licensed to perform this operatio
For DP to storoence operations (Copy, replication...etc), the storoence device (including VSA) needs to be licensed.
At times, the license on the device may expire, and the DP operation will report a [major] error -
Cannot open device (StoreOnce error: Client not licensed to perform this operation)
DP support can confirm the issue with a review of the media agent debugs, which more than likely will report OSCLT_ERR_NOT_LICENSED
Post the confirmation, it is recommended to contact the vendor (HPE) for further help in relevance to the device license
