We also include a utility called vvshowdevs that will rescan your SCSI bus for
devices that may not have been ready or available at boot. This utility is run from
the command line and will display its results for you. Another way of forcing a
SCSI rescan is to delete the vvdrc.rc file from the /tmp directory.
SCSI Drivers
ScanShop may have installed Vividata’s SCSI drivers on your system if your
system is not one that provide SCSI drivers in the kernel. The names and
installation requirements of SCSI device ports (i.e. “drivers”) are system-
dependent and are described in the following table
:
• Your SCSI device ports do not have read and write permissions set for all
users. Refer to the “SCSI Drivers” section to determine the name of the SCSI
drivers on you system, and check the permissions on those files. On some
systems, the files are symbolic links; make sure the files they link to also have
sufficient read and write permissions.
• You do not have SCSI ports and/or a compatible SCSI driver installed on
your system. Refer to the “SCSI Drivers” section to determine the correct
installation procedure for your platform. On OSF/1, HP-UX 9.x, and IRIX,
the SCSI ports should already exist on your system, so no additional drivers
are necessary.
• You do not have read and write permissions set for /tmp or on /tmp/vvdrv.rc.
Make sure the permissions on these files are sufficient.
