PROBLEM: (94209) (PATCH ID: OSF445-540)
********
/sbin/ddr_config is a tool that reads the text file /etc/ddr.dbase
and produces the binary Dynamic Device Recognition (DDR) database
file /etc/ddr.db that the Tru64 Operating System reads to obtain
device driver settings.
One of the optional parameters for a device in /etc/ddr.dbase is
ReadyTimeSeconds, it determines how long before an I/O request times
out on that device. Some tape devices can take 300 seconds (5 minutes)
or more to become ready.

If the ReadyTimeSeconds value in /etc/ddr.dbase is larger than 255,
/sbin/ddr_config will print an error message, refuse to accept it
and will revert to the default value of 45 seconds. If you have a
tape drive that takes a long time to get ready and you experience
I/O timeouts, consider installing this patch. It contains a new
ddr_config that allows ReadyTimeSeconds values up to 86400 seconds
(24 hours).

You may then edit /etc/ddr.dbase (or a copy of it) and increase
ReadyTimeSeconds for your tape drive, for example:

        ReadyTimeSeconds = 300

Recompile /etc/ddr.dbase by issuing the command:

        ddr_config -c [filename]

If you make sure that all devices of that type are unmounted
and nobody is using any of them when you issue ddr_config, the
change will take effect without rebooting your system.
