I find it hard to believe that this poses a problem for most people these days. The following is taken from a 1950 with RHEL5 and OMSA 5.5.0, that has been up for 95 days, and runs various omreport commands (via a Nagios plugin) every ~5 mins: # ps -eo pid,cputime,rss,size,args | egrep PID\|dell | grep -v egrep PID TIME RSSSZ COMMAND 5349 00:00:02 2224 102728 /etc/delloma.d/oma/bin/dsm_om_shrsvc32d 5798 00:31:13 10300 171868 /opt/dell/srvadmin/dataeng/bin/dsm_sa_datamgr32d 6142 00:01:25 3060 22156 /opt/dell/srvadmin/dataeng/bin/dsm_sa_eventmgr32d 6160 00:00:00 2340 136676 /opt/dell/srvadmin/dataeng/bin/dsm_sa_datamgr32d 6176 00:15:21 3696 52840 /opt/dell/srvadmin/dataeng/bin/dsm_sa_snmp32d Neither the processing nor the memory usage seems very alarming to me. This is not a scientific test by any means, it is just a random example from a random host. However, I can certainly see that there exist special cases where you don't want to run OMSA in order to save processing power and/or memory, but not in the general case. To me, the benefits from running OMSA outweights the disadvantages. You'll have a certified tool from Dell for monitoring and managing your servers. If OMSA reports that something is wrong, Dell support will take it seriously. And OMSA lets you monitor much more than just the status of your hardware RAID. > It look me about half a day of tinkering around to get Nagios set up and > monitoring a 2950, 1950, two 2950s, two 2650s, and a 2550 - including > RAID status of PERC5, 4, and 3 on those systems. > > Once the initial install is done, it's easy (as in less than 5 mins > setup) to monitor additional systems. > > I posted notes here: > http://stevejenkins.com/blog/2009/12/helpful-links-for-setting-up-nagios > -and-nrpe-on-rhel-5-and-centos-5/ If you had been using OMSA, you would have one tool to monitor and manage your hardware RAID (and also other aspects of the servers), and one Nagios plugin to rule them all ;) PS. The 2550 can't run any modern OMSA versions, so it's pretty much a lost case in that respect. Cheers, -- Trond H.

RE: RAID Perc 5 monitoring
I used to use OMSA a couple versions ago, but didn't like how much processing and memory it used. It look me about half a day of tinkering around to get Nagios set up and monitoring a 2950, 1950, two 2950s, two 2650s, and a 2550 - including RAID status of PERC5, 4, and 3 on those systems. Once the initial install is done, it's easy (as in less than 5 mins setup) to monitor additional systems. I posted notes here: http://stevejenkins.com/blog/2009/12/helpful-links-for-setting-up-nagios -and-nrpe-on-rhel-5-and-centos-5/ The good news is that with Nagios, there's a good chance someone else has done all the hard work for me already, and I just have to Google till I find a script that does exactly what I want!

I'm not running OMSA on Debian/Ubuntu myself (we're a Red Hat shop), but the procedure looks quite straightforward. Dell doesn't support any Debian based distributions, but the nice folks at SARA maintains a Debian/Ubuntu port of OMSA: https://subtrac.sara.nl/oss/omsa_2_deb OMSA is superior to other means of managing/monitoring Dell servers, IMHO. If Nagios is your cup of tea, there are a wealth of plugins available that integrates OMSA and Nagios. PS. With OMSA installed you can manage and monitor much more than just the RAID type and status.

Hi, Thanks, I should have mentioned that I have a 64 bit platform. It seems all that is available for download is megactl-0.4.1.i386.tar.gz. Will this work with 64 bit OS? Even better, is there a Debian 64 bit package for this somewhere?

OMSA if your nights are long. megasasctl can send you periodic reports of health of all physical and logical disks. On SAS disks you can also check disk temperature and various other log pages, or initiate disk self-tests in disk firmware. One case where this is handy is when you're about to rotate a new disk in after a failure; it's nice to be able to do a long self-test of the new disk first so you don't have it fail in the middle of the rebuild. http://sourceforge.net/projects/megactl/ You may wish to build from SVN, particularly if you need PERC6 RAID6 support.

RAID Perc 5 monitoring
Hi, I recently bought a used PowerEdge 1900 with a perc 5 controller. I am running Ubuntu LTS 8.04 on it, and I'm wondering if there are any software tools that I can use to monitor and manage the array? I have it set up as RAID 10. My controler card is: # lspci 02:0e.0 RAID bus controller: Dell PowerEdge Expandable RAID controller 5 It is in a remote location, so command line tools would be great. I don't run any gnome or windowing at all. Even if I have to do it by hand would be fine... Thanks!
