I tried echo "scsi add-single-device 0 2 0 1" > /proc/scsi/scsi as sugested at http://h20565.www2.hpe.com/hpsc/doc/public/display?sp4ts.oid=5386549&docId=mmr_kc-0114289&lang=es-es&cc=es&docLocale=en_US but there was no change and robotic device was not detected.

Thanks in advance for any suggestions and support.
