3Ware – Manage your RAID arrays via http
3Ware provide a good CLI to their products. I
wrote about that a couple of weeks ago.
They also provide a very nice web interface, available as the
sysutils/3dm port. A
recent
discussion on the FreeBSD AMD64 mailing list brought this to my attention.
I had used the 3DM tool from 3Ware, but had forgotten about it. I also did
not know there was a web interface. I was glad to find it.
CLI is great, and I’ve used it many times. But a web interface can present
information in a fashion that CLI cannot. Hyperlinks make it easier to get to
where you want to be.
I will show you how to install the port, and provide some screen shots to give
you an idea of how the web interface works.
Installing the port
To install the port:
cd /usr/ports/sysutils/3dm/ make install clean
To start the port, add this to /etc/rc.conf:
3dm_enable="YES"
And issue this command
/usr/local/etc/rc.d/3dm start
First time configuration
The URL used to access the web interface depends on the OS version you using. If it’s 32 bit,
you can use https. Otherwise, you use http. In all cases, just
browse to the hostname of your server, using port 888 (the default).
For example:
http://opti.example.com:888/
You should see something like this:
The default password is 3ware. Full documentation is installed at /usr/local/share/3dm2/en/.
I found out about the password by reading 3DM_2_OLH-2-04.html.
After logging in, you should see this:
Your first action should be changing the password and perhaps changing the port
upon which the application listens. You should
click on 3DM 2 Settings to change these values.
I also recommend restricting access using your
firewall. As far as I know, there is no way to set the IP address upon
which the interface listens, and it listens to all IP addresses. However, you
can disable remote access using the RemoteAccess option in
/usr/local/etc/3dm2/3dm2.conf.
Controller and Unit information
Details information about your controller is easily found:
You can view the unit information for your controller. In my case, it shows the
main RAID array and the two hot spares.
Detailed information regarding each unit is also available. The following screen
shot shows the 6 drives involved in my RAID-10 array. Unit zero consists of
three RAID-1 arrays. The data is then striped over these three arrays.
Looking at unit 1, which is just a single drive, held as a hot spare, there’s not
much to see:
You can also see all the drives, the unit they are in, and their firmware versions.
Detailed additional information about each drive is also available. What I find
interesting about this screen shot is it seems to indicate that NCQ is not
supported. If I recall correctly, I think I must manually set NCQ on for each
drive.
You can also modify the controller settings through this screen:
But wait! There’s more!
I’ve only shown a few screen shots from the 3DM web interface. There is much
more functionality than is displayed above. Here are a few of the items
not shown above:
- Scheduling (for rebuild/migrate tasks)
- Maintenance (perform these unit tasks: verify, rebuild, migrate, remove, and delete)
- Monitor alarms
- Monitor the battery backup unit
- Set up email notification
If you have a 3Ware card, then
the sysutils/3dm port will
be a useful tool to add to your collection.
I will continue to leave 3DM
running, mainly because of the email notification system build into the daemon,
but I’m sure I’ll use the tool when the time comes to maintain the array.
In addition, I will also continue to run my
NetSaint 3Ware plugin.
