FreeBSD IBM ServeRAID Manager logoAnd yet another FreeBSD-related post: After [updating] the IBM ServeRAID manager on my old Windows 2000 server I wanted to run the management software on any possible client. Given it’s Java stuff, that shouldn’t be too hard, right? Turned out not to be too easy either. Just copying the .jar file over to Linux and UNIX and running it like $ java -jar RaidMan.jar wouldn’t do the trick. Got nothing but some exception I didn’t understand. I wanted to have it work on XP x64 (easy, just use the installer) and Linux (also easy) as well as FreeBSD. But there is no version for FreeBSD?!

The ServeRAID v9.30.21 manager only supports the following operating systems:

  • SCO OpenServer 5 & 6
  • SCO Unixware 7.1.3 & 7.1.4
  • Oracle Solaris 10
  • Novell NetWare 6.5
  • Linux (only certain older distributions)
  • Windows (2000 or newer)

I started by installing the Linux version on my CentOS 6.8 machine. It does come with some platform-specific libraries as well, but those are for running the actual RAID controller management agent for interfacing with the driver on the machine running the ServeRAID controller. But I only needed the user space client program, which is 100% Java stuff. All I needed was the proper invocation to run it! By studying IBMs RaidMan.sh, I came up with a very simple way of launching the manager on FreeBSD by using this script I called serveraid.sh (Java is required naturally):

  1. #!/bin/sh
  2.  
  3. # ServeRAID Manager launcher script for FreeBSD UNIX
  4. # written by GAT. http://www.xin.at/archives/3967
  5. # Requirements: An X11 environment and java/openjdk8-jre
  6.  
  7. curDir="$(pwd)"
  8. baseDir="$(dirname $0)/"
  9.  
  10. mkdir ~/.serveraid 2>/dev/null
  11. cd ~/.serveraid/
  12.  
  13. java -Xms64m -Xmx128m -cp "$baseDir"RaidMan.jar com.ibm.sysmgt.raidmgr.mgtGUI.Launch \
  14. -jar "$baseDir"RaidMan.jar $* < /dev/null >> RaidMan_StartUp.log 2>&1
  15.  
  16. mv ~/RaidAgnt.pps ~/RaidGUI.pps ~/.serveraid/
  17. cd "$curDir"

Now with that you probably still can’t run everything locally (=in a FreeBSD machine with ServeRAID SCSI controller) because of the Linux libraries. I haven’t tried running those components on linuxulator, nor do I care for that. But what I can do is to launch the ServeRAID manager and connect to a remote agent running on Linux or Windows or whatever is supported.

Now since this server/client stuff probably isn’t secure at all (no SSL/TLS I think), I’m running this through an SSH tunnel. However, the Manager refuses to connect to a local port because “localhost” and “127.0.0.1” make it think you want to connect to an actual local RAID controller. It would refuse to add such a host, because an undeleteable “local machine” is always already set up to begin with, and that one won’t work with an SSH tunnel as it’s probably not running over TCP/IP. This can be circumvented easily though!

Open /etc/hosts as root and enter an additional fantasy host name for 127.0.0.1. I did it like that with “xin”:

::1			localhost localhost.my.domain xin
127.0.0.1		localhost localhost.my.domain xin

Now I had a new host “xin” that the ServeRAID manager wouldn’t complain about. Now set up the SSH tunnel to the target machine, I put that part into a script /usr/local/sbin/serveraidtunnel.sh. Here’s an example, 34571 is the ServeRAID agents’ default TCP listen port, 10.20.15.1 shall be the LAN IP of our remote machine hosting the ServeRAID array:

#!/bin/bash
ssh -fN -p22 -L34571:10.20.15.1:34571 mysshuser@www.myserver.com

You’d also need to replace “mysshuser” with your user name on the remote machine, and “www.myserver.com” with the Internet host name of the server via which you can access the ServeRAID machine. Might be the same machine or a port forward to some box within the remote LAN.

Now you can open the ServeRAID manager and connect to the made-up host “xin” (or whichever name you chose), piping traffic to and from the ServeRAID manager through a strongly encrypted SSH tunnel:

It even detects the local systems’ operating system “FreeBSD” correctly!

IBM should’ve just given people the RaidMan.jar file with a few launcher scripts to be able to run it on any operating system with a Java runtime environment, whether Windows, or some obscure UNIX flavor or something else entirely, just for the client side. Well, as it stands, it ain’t as straight-forward as it may be on Linux or Windows, but this FreeBSD solution should work similarly on other systems as well, like e.g. Apple MacOS X or HP-UX and others. I tested this with the Sun JRE 1.6.0_32, Oracle JRE 1.8.0_112 and OpenJDK 1.8.0_102 for now, and even though it was originally built for Java 1.4.2, it still works just fine.

Actually, it works even better than with the original JRE bundled with RaidMan.jar, at least on MS Windows (no more GUI glitches).

And for the easy way, here’s the [package]! Unpack it wherever you like, maybe in /usr/local/. On FreeBSD, you need [archivers/p7zip] to unpack it and a preferably modern Java version, like [java/openjdk8-jre], as well as X11 to run the GUI. For easy binary installation: # pkg install p7zip openjdk8-jre. To run the manager, you don’t need any root privileges, you can execute it as a normal user, maybe like this:

$ /usr/local/RaidMan/serveraid.sh

Please note that my script will create your ServeRAID configuration in ~/.serveraid/, so if you want to run it as a different user or on a different machine later on, you should recursively copy that directory to the new user/machine. That’ll retain the local client configuration.

That should do it! :)
