Explanation
Cisco CallManager software was changed
to find the correct WS-X6608 port type.
The problem was due to the file system
backup utility locking the file using the
win32 LockFile(). LockFile either allows a
shared Read lock or an exclusive Read or
Write lock. If a shared Read lock has been
obtained by a process; no process
(including the one that had first opened the
file) can write to that file. Thus, if a user
attempted to update DCD while the backup
utility held a lock on DCD's DB volumes,
DCD was unable to write to disk and
consequently got into an awkward state.
DCD now obtains an exclusive Read/Write
lock on startup on its DB volumes. This
lock prevents any other process from even
opening the file. Thus, DCD is guaranteed
that no process can deny it (DCD) write
access to its own files once it (DCD)
successfully comes up.
