When a repository resides on a NAS via a CIFs connection, one or more repositories may go offline, and you may see an error stating that the storage location is unavailable. During this time, you are still able to browse, create, and delete files on that CIFs location, as expected through Windows Explorer.
The exact cause of this is not yet known. However, environmental testing suggests the AppAssure connection session or authentication authority may be “lost” or "dropped" by the NAS. This is supported by the fact that the below resolution has shown repeated success, when applied.
The recommended solution to connectivity issues regarding CIFs connections is to replace the CIF shares with iSCSI connections.
However, this is not always possible. Some NAS devices are not iSCSI capable, or it may be quite unfeasible to perform that action. In this case, the follow describes a workaround that has seen large success in preventing these CIFs session “losses.”
ECHO keepalive > “\\storage\folder\keepalive.txt”
PING -n 5 127.0.0.1
This process of creating a small file and then deleting will keep the system from “losing” the session needed for proper functionality of the repositories.
