Have you tried the Direct point-to-point connection Tape <==> server ?
That is, without going through the SAN switch. You must discard the ZONE configuration on the SAN switch. This error ERR=Input/output error has only occurred to me when the Drive (by license) is Read Only. It happened to me with a Drive from an ORACLE robot. Or when the tape is damaged.
