After you have edited the "st_conf.c" file and added the above entry, rebuild the
kernel using the standard procedure (for further help, refer to the man pages of
config).
Install the tape SBB into the StorageWorks enclosure and power on the system. We
recommend that the SWXTE SCSI device address be set to ID 4 or 5.
NOTE
If your SCSI host adapter is supported by the “probe-scsi”
command, then it may be used to verify at the boot prompt
that the connected device is correctly attached to the system.
Reboot the system using the following command at the boot prompt:
>boot
The system reboots with the newly compiled kernel and creates special files in /dev so
that it can communicate with the SWXTE. Verify that “DEC EXB-8505 8mm
Helical Scan /w Compression” is displayed as a target when the system is
booting.
