Red Hat 5.3 OS is used in T3000. Check dmesg log, error information is that program nmhs is using a deprecated SCSI ioctl, please convert it to SG_IO.
No need to handle. Nmhs process of Oracle database invokes a scsi_ioctl_send_command command which is not supported by system. So transfer this command into sg_scsi_ioctl to dispense in system.
