Containerised Dell System Utilities

Dell OMSA on CentOS

Deploy the Dell/EMC OpenManage Server Administrator tools into a Docker container and run DSU (Dell System Update) when executed.

Dell ISM on Ubuntu

Deploy the Dell/EMC iDRAC Service Module into a Docker container and run the ISM when executed.

Notes

The following kernel modules are used by the ISM:

dcdbas
dell_rbu
ipmi_devintf

Licences

Included is dcism-setup_usbintf.sh - a rewrite of the largely-broken script provided by Dell themselves. The licence under which the original script is distributed is unclear from both its contents and the installation procedure which created it. Any licence text distributed with this repository does not, therefore, apply to this file.

Known issues

• The DSU process has not been thoroughly explored to ensure that all required setup and dependencies are initialised.

Known Docker issues

The below issues were encountered when using Docker to provide virtualisation services. When using podman and host-networking, IPv6 is fully supported and so there is no further issue.

• The linux kernel doesn't virtualise the sysctl interface, which is the only method docker provides to control use of IPv6 if supported by the host system but not docker itself. This means that one of three unpalatable options are faced:

  1. Allow docker to apply sysctl changes and all containers work (without IPv6) but the host system loses IPv6 connectivity whenever the container is started;
  2. Make no changes, and if the container receives an IPv6 response faster than IPv4 when installing packages, it will hang or fail;
  3. Configure the docker daemon for IPv6 support which - as of release 19.03 - is still non-default, awkward, and brings other limitations.

Solved issues

• The ISM binary appears to be operating as expected from the OS level, but the iDRAC system itself reports that the ISM disconnects shortly after launch.
