Identifying BlueArc Mercury M100 Hardware Revision

The BlueArc 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. 192.0.2.200 and 192.0.2.201).
2. Then ssh into the SMU (eg. ssh manager@smu). Hit q to get to the command prompt.
3. At the command prompt of the SMU ssh to each cluster node individually (eg. ssh 192.0.2.200).
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))

BlueArc 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 BlueArc 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
