directories is provided by
SCAVENGEDSKDIRECTORY; scavenging for Pilot is
provided by the System Tool.
Lisp directory failures show up as infinite looping or
I
other aberrant behavior while the system is doing a
directory search or enumeration. To repair the
directory, return to the top level (the Interlisp-D
Executive) and call
(SCA VENGEDSKDI RECTORY
VOLUMENAME) [Function]
This function deletes the old directory, then
reconstructs it from the files on the given logical
volume.
Pilot failures manifest themselves as "HARD DISK
ERROR" breaks within Lisp. To fix such a failure,
return to the top level, log out of Lisp and get into
the System Tool. Invoke the Scavenge! command
for the damaged logical volume. If the System Tool
reports that there were no problems, proceed back
to Lisp and call SCAVENGEDSKDIRECTORY as
described above.
On the other hand, the System Tool may report
problems. Each problem is described by a message
in the format shown below:
[filelO] type
=
file type; problem description
The filelD is a pair of numbers separated by a
comma. The file type is a single number. If it is in the
range 10048 to
i
0077 inclusive, the damaged file
belongs to the Lisp local file system. Any other file
types may be safely ignored.
If the file is in the Lisp local file system, you should
examine the problem description to determine your
next course of action. There are five possible
problems.
