It summarizes drive configuration options, as well as changes that may be required at the operating system level. Note: Seagate makes no Warranty of any kind with regard to this document.

Never configure your target device for ID 7 unless you are absolutely sure that the controller is not addressed for ID 7. Figure 1 shows the locations of the SCSI ID address jumpers for the Viper 200.

The minimum recommended controller would be a glm controller which is a Ultra Wide controller. We recommend Ultra2 SCSI capable controllers capable of 80MB/s data transfer. Ultra 3 controllers supporting 160MB/s transfer rates can also be used. Configuring the device file st.conf To configure Solaris 2.

If you are replacing a tape device with the same SCSI ID you may want to delete the st devices from the /dev/rmt directory (recommended). When using commands that require a blocking factor such as tar, ufsdump, ect., we suggest a minimum factor of 64.
