The Snap Appliance include SCSI HBAs as part of the unit. This HBA can be used to attach external devices such as tape drives and tape libraries. The default SCSI ID for the HBA set to ID 3 which can not be changed. (note: most SCSI HBAs default SCSI ID is set to ID 7).
A NEO tape library was attached to a Snap Appliance where some of the SCSI ID's were higher than ID 3 and some were lower than ID 3. This setup caused a communication problem with the library and drives.
Change all of the SCSI ID of the Neo to be higher than ID 3.
