Manage and Monitor Dell PERC RAID under Linux

I’ve repurposed an old Dell PowerEdge 1500SC with a PERC 3/SC RAID card for use as a Linux phone server running Asterisk. Unfortunately, the only version of Dell OpenManage that works for the 1500SC (OpenManage 4.5 docs and download) is only supported under Redhat 7.1. I’m using CentOS 5.2, so I’m out of luck.

I eventually found that I could use Linux tools for the LSI MegaRAID SCSI 320-1LP to control and monitor the PERC 3/SC. Visit this download page and search for “OS: Linux”.

Here is a brief summary of three of the tools and what they do. Obviously these are not supported Dell tools; I’m not even sure that the PERC 3/SC is the same as a 320-1LP. The tools are working for me, but use at your risk!


Proactively monitor for issues; email root if found.

  1. Unzip to /var/megamon on Linux machine. 
  2. Mark ALL files (except readme.txt) as executable by all (755).
  3. Run ./install to copy files.
  4. Adjust polling frequency in /etc/megapoll.conf” if desired. I left default 200 seconds.
  5. Restart system, or run “/etc/rc.d/init.d/raidmon start” to start monitoring.
  6. Check for output in “/var/log/megaserv.log”.

Tip I use WinSCP to move files from my Windows desktop and to change file permissions.

Contrary to the readme.txt, “MegaCtrl -help” doesn’t do anything. “MegaCtrl -start” may start the service (like “raidmon start” above).

You should get emails every time there is a change on the RAID array, e.g. adding or removing a logical drive or, hopefully, if a drive fails. You’ll also get a bunch of mails when the Linux server retarts.


GUI that runs under Putty. Looks like the same GUI that is available during system startup by pressing Ctrl-M. Yes, this means you can perform RAID maintenance while the system is up!

Unzip to /var/megamgr on Linux machine and mark megamgr.bin as executable.

cd /var/megamgr

# Start GUI
sh megamgr


Hint To get the function keys to work and the line drawing characters to look right, set Putty as follows:

  • Terminal > Keyboard > The function keys and keypad:  VT100+
  • Window > Translation > Received data assumed to be in which character set:  ISO-8859-1:1998 (Latin-1, West Europe)


Command-line management.  This is probably not needed since MegaMgr allows remote GUI through Putty.

Unzip to /var/megarc on Linux machine and mark megarc.bin as executable.

cd /var/megarc
