Help with Errors Storage Daemon - Virtual Tape Library

[Miguel Santos]

Hi,

I have a Virtual Tape Library based on HPE Store Once. The tapes have their barcodes, but I see non-fatal errors - which I would like to get rid of - when starting reading and releasing tapes. See some examples:

Here is the configuration of the pool/device from the Director:

===

Here is the configuration of one of the drives:

===

Any tip to get rid of these errors?

Thank you.
