As per Microsoft: "In almost all cases, these messages are being posted due to hardware problems with either the controller or, more likely, a device that is attached to the controller in question. The hardware problems can be associated with poor cabling, incorrect termination or transfer rate settings, lazy or slow device responses to relinquish the SCSI bus, a faulty device or, in very rare cases, a poorly written device driver". See ME188646 for a possible cause of this event`s appearance.
See ME153128 and ME314093 to find out how to troubleshoot error messages about event id 9 and event id 11.

Backup operations using an HP (Hewlett-Packard) C1533 DAT drive result in the backup process terminating abruptly and the System Event Viewer Log will report this event. See ME211214.
If Backup Exec for Windows NT/2000 jobs are reporting hardware errors such I/O Errors, Semaphore Timeout errors, and Event ID 9, 11 and 15 the in System Event Log, this may be due the fact that the SCSI driver on the system is out of date. See Veritas TechNote ID: 231918 link.
When the I/O request expires (times out), the driver resets the SCSI bus. Although this could indicate other problems, this could also be caused in some configurations by powering on or off devices on the shared bus, if the bus is differential. Time-out events could indicate cabling, termination, or SCSI hardware configuration problems. See ME259237.
