One of my clients is reporting than when she clicks the "Swap" button on a camera view to go to the archive, she gets a "No Archive Available..." error message. However, if she goes to the archive directory, she'll see the archive. If she then goes back to the original view, and clicks the "Swap' button, the archive pops up.
I found this in the Cisco docs:
No archive available for archive_name
This message can occur if loading archive video data takes too long and the system times out. This error should not occur unless there is a problem reading the archive data from the storage location.
Verify that the archive is running and that it contains video data: On the VSOM Administrator page, click Servers, then click the name of the VSMS server with this archive. The archives tab shows a list of all archives and their status, and the time of the first and last video frame. When the recorded video expires, the first frame and last frame times are empty.
However, the archive is available so that doesn't address the situation.
