Dell OpenManage

Dell OpenManage Server Administrator (OMSA) is the suite of tools provided by Dell for managing an individual server. See the official OpenManage site for product information.
Obtaining OMSA
OMSA is included with the purchase of every new PowerEdge server. It comes on a CD included in the server's cardboard box.
Each new version of OMSA may be also downloaded from Search for Files by Description: "OpenManage Server Administrator linux"
The Dell unofficial yum repository also carries OMSA to ease installation.
OMSA 5.0 and above
  • Starting with OMSA 5.0, all necessary kernel components are now fully open source, GPL licensed, and included in 2.6.x. This includes the OpenIPMI drivers/char/ipmi/ipmi* drivers, drivers/firmware/dell_rbu Remote BIOS Update driver, and drivers/firmware/dcdbas Dell Base Systems Management driver. This should make it much easier to install and run OMSA on a variety of Linux distributions (userspace library incompatibilities, if any, notwithstanding).
  • OMSA 5.0 has full support for:
    • Red Hat Enterprise Linux 3 Update 6 or higher
    • Red Hat Enterprise Linux 4 plus Updates
    • Novell/SuSE Linux Enterprise Server 9 Service Pack 3 or higher
  • Unofficial: There's a Live CD of CentOS 4.4 plus OMSA 5.1 available.
  • Unofficial: There's a Live CD of CentOS 4.3 plus OMSA 5.0 available.
OMSA for Novell/SuSE Linux Enterprise Server 9
OMSA 4.x isn't officially supported by Dell on Novell/SuSE Linux Enterprise Server 9. However, we have made available builds of OMSA 4.4 that work on SuSE (with the exception of the web server and online diagnostics components). These builds are available here.
OMSA Tips and Tricks
  • Installation may fail if your kernel sources are not available in the expected place. You can make installation succeed if you make /usr/src/linux-2.4 a symlink to your actual kernel source location.
  • OMSA 1.5 has a check to prevent installation on RHEL 2.1 ES (which hasn't been tested by the OMSA team, though the code is identical to that of 2.1 AS). This test was removed in OMSA 1.6. If you must run OMSA 1.5 on RHEL 2.1 ES, change /etc/redhat-release from saying "ES" to say "AS" and install OMSA, then switch it back.
  • OpenManage Server Administrator 1.4 - OMSA 1.4 fixed the "ntp time skew" problem reported on the linux-poweredge mailing list.
  • OpenManage Server Administrator 1.2 - With OMSA 1.2 or earlier, if you have difficulty rebuilding the source code shim because of an error in including <linux/malloc.h>, you may change that line to include <linux/slab.h> instead and it will work.

Dell Certified Management addons

Dell, in partnership with Platform Computing and the High Performance Computing Community, is pleased to provide the Dell OpenManage Nagios Plug-in.


Intelligent Platform Management Interface (IPMI) is a standards-based method of obtaining information such as fan speeds, temperatures, voltages, System Event Log entries, and the like. Dell x6xx and newer systems implement IPMI controllers, either as Baseboard Management Controllers (BMCs), or on add-in Dell Remote Assistant Controller (DRAC) cards.
Dell engineers are active contributors to several Open Source IPMI projects, as well as participate in the Distributed Management Task Force (DMTF) standards organization.
