1305 - Installing a StorageServer via command-line fails to add a firewall rule

This article relates to Bug 34853 (still active) in Storage Platform release v20.9.

Symptom

When the command-line install argument (StorageServer.exe) is used to install or upgrade a second StorageServer or MirrorServer, a firewall rule for the new StorageServer.exe location will not be added automatically. The result is that the StorageServer cannot queue tasks on the MirrorServer. A log entry similar to the following can be seen in the Event Viewer:

Solution

The workaround is to manually apply a rule to the firewall, allowing access to the StorageServer.exe.
