Identifying HDS HNAS Mercury M100 Hardware Revision

The BlueArc / HDS HNAS Mercury M100 has had minimally two distinct hardware revisions. The initial revision of the hardware was sometimes unreliable. To determine which hardware revision you are running do the following:

  1. Determine the management IP addresses of the nodes in your Mercury cluster . To do this log into the SMU (eg. https://smu) as admin. Then go to Home -> Server Settings -> Cluster Configuration and record the IP addresses of the cluster nodes (eg. and
  2. Then ssh into the SMU (eg. ssh [email protected]). Hit q to get to the command prompt.
  3. At the command prompt of the SMU ssh to each cluster node individually (eg. ssh
  4. Run the following command: ver -h | grep Tachyon
  5. The output of that command will determine which hardware revision you are running:
    1. Rev A hardware is identified as follows: Tachyon: QX4 1.2 (HPFC-6440C)
    2. Rev B hardware is identified as follows: Tachyon: QE4+ 1.1 (PM8036 (Rev B))

HDS HNAS Bluarc EVS Routing

You may have the need to set a default gateway on a BlueArc EVS (Enterprise Virtual Server). After you have configured the networking side of your EVS (via Home -> Server Settings -> EVS Management). Then go into Home -> Network Configuration -> Routing and add a gateway route for the subnet in question.

Disabling CIFS Authentication on a HDS HNAS EVS In Standalone Security Mode

You might need to create a BlueArc EVS (Enterprise Virtual Server) with CIFS security disabled. You can't do this through the GUI. So at the SMU command line:

1. Work out the EVS ID:

evs list

2. Select the EVS:

evs-select <id>

3. Disable domain authentication for CIFS:

cifs-auth off

Scheduling a Service to run once per day

If you need a service to run once per day at a specific time and then exit, you can do so with the following

  1. Create your service as normal
  2. Set Settings -> Upon Program Exit -> Disabled (or Report the Termination)
  3. Set Scheduling -> Schedule a Restart -> At Specific Time

This will cause FireDaemon to run your app initially to completion. When the app quits FireDaemon doesn't restart it. At the "Specific Time" the app is run again and the cycle continues.

FireDaemon On Windows 8 and Server 2012

Windows 8 and Windows Server 2012 are here with the new Metro interface. FireDaemon Pro and FireDaemon Fusion both install and run successfully on both versions of Windows. FireDaemon services can be successfully installed and run. Start In Session and Restart In Session also works. There is one issue that we have encountered with both Windows 8 and Server 2012 and that is the Interactive Services Detection service fails to run and bombs out with the error "The Interactive Services Detection service terminated with the following error: Incorrect Function". To fix this get into the Registry Editor and look for HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Windows and change NoInteractiveServices from 1 to 0. Once you make that change you will see the Interactive Services Detection dialog and you can switch desktop over to Session 0.

Are user passwords encrypted?

This was a question that was recently asked in a support ticket and it is a very good one.  For those of us who are concerned about security, this is very important. Rest assured though, the service password is not stored in the filesystem. When the service is created is it passed to the Service Control Manager where it is hashed and stored in the SAM.

Network Shares and FireDaemon

You can run an executable as a service under FireDaemon even if that executable resides on a network drive. In order to run an executable off of a network drive the following must occur or be true:

    1. The executable must be placed in a directory that is shared out
    2. The executable can be normally referenced via mapped drive (eg. L:\pathfile.exe) or via UNC path (eg. \\serversharepathfile.exe).
    3. Mapped drives or UNC paths can only be used if the service is run as a nominated local or domain user (see next point).
    4. If you intend to run the service as a nominated local or domain user then that user has must have permission to access the network resource (ie. share) in question. Further, if you want your application to Interact With The Desktop then you need to ensure that the local or domain user is in the Administrator's group.
    5. If you want to use a mapped drive then you are going to have to setup a Pre-Service Program to complete the mapping.
    6. The application working directory can be either a mapped drive or UNC path - however, if a UNC path is used, a trailing slash () must be supplied (eg. \\serversharepath).
See for more information.

Unable to install FireDaemon

If you've ever encountered an error like "Installaware Wizard: Setup database not found" while trying to install FireDaemon or other applications, the reason is because your MSI database might be corrupt. The MSI database stores information about all installed MSI applications. To fix it, download the MSI Cleanup Utility from Microsoft from Ensure that you remove any remnants of the FireDaemon installer - then attempt to install again. Also look at deleting the MSI uninstaller. You will find it at a location similar to the following:

Pre-Post Service Executable's die before they run

If your Pre-Service or Post-Service executable is dying before it has a chance to run, the problem is that the execution time is too low. By default, it is set to 3000ms (3 Seconds). Try setting it to something higher (you might have to keep increasing until you find the proper time).

Quick Shortcuts to Services Control Panel, Event Viewer and Task Manager

If you need to access the Services Control Panel, Event Viewer or Task Manager there's a way to do it a lot faster. Rather than going through the run box, start menu, or right clicking my computer you can do it entirely through the FireDaemon window! Simply click the "File" menu and select your desired tool there.
