We are currently using Commvault v10 with Dell ML3 tape libraries. Initially, we encountered a media mount error on the library. After replacing the drives, we began receiving the following error intermittently on a few of the tape libraries. Once the drives were cleaned, backups resumed successfully.
However, with one particular tape library, the issue persists even after replacing the drives.
Note: During backup, the job runs for a few GB and failing with an error.
Error Code: [40:73]
Description: Error occurred in Library [Vxxxx], Drive Name [IBM ULT3580-HH7_2], Barcode [S77370L7], Path [\\.\Tape1] [Drive did not respond to commands properly. There may be too many drives on the SCSI Bus operating at the same time. Try reducing the number of drives on the SCSI Bus. Try reducing the synchronous transfer rate on the SCSI Controller. Or two controlling programs may be accessing the library concurrently. For more details, please check to see a corresponding Operating System event for this device.]. For more help, please call your vendor's support hotline.
