Our site has resolved the broken back link problem for v4common.dir.
My thanks to all who commented about the problem on the net, and to
Rob Eulenstein at Colorado TSC who provided the fix.
As suggested earlier on the net, there is a problem with ANAL/DISK/REPAIR
and back links. In a nutshell, the problem occurs because the file name
in the header did not match the "real" file name. ie the file name in question
was dev:[0,0]V4COMMON.DIR, but the header thought it was SYSCOMMON.DIR.
(DUMP/HEADER confirmed this.) There were 2 ways to resolve the problem.
a) $ ANAL/DISK/REPAIR/CONFIRM again on the system disk. This solution
was NOT selected since I needed a quiet system disk.
b) $ RENAME dev:[0,0]V4COMMON.DIR dev:[0,0]SYSCOMMON.DIR
$ RENAME dev:[0,0]SYSCOMMON.DIR dev:[0,0]V4COMMON.DIR
Solution (b) was put into a command file so that V4COMMON would vanish
for the shortest possible time, and executed. DUMP/HEADER verified that
the file name in the header now matched the "real" file name. A subsequent
test of the symbiont verified that the problem is now resolved.
Perhaps this on-line patch will help other sites. I certainly learned
something new about the VMS disk structure today. Thanks again. b.
