About nonstandard tape drives
Solaris includes the device drivers that support most standard devices.
To receive the most current support for devices, you should install the latest Solaris patch for the st driver.
However, if you have a device that Solaris does not support, the device manufacturer should provide the software to install and administer the device properly. In addition, the device vendor should contact Oracle to add support for the device to Solaris.
For more information about what you need for unsupported devices, contact the device vendor. Also see the Solaris devices and file systems documentation.
