The subsequent limitations are applied for the IBMtape driver that runs on a Solaris host.
Maximum supported number of tape devices 1024
Maximum supported number of HBA ports 56
Maximum supported number of paths for a device (DPF/ CPF) 16/16
Maximum LUN size per target for FC HBA

Every opened tape device uses a certain amount of resources. The user must also consider other resources such as physical memory and virtual space on the system before you attempt to reach the limits.
