The following symptoms may occur once a Dell server is upgraded to VMware ESXi 6.7 Update 3. If Dell OpenManage Server Administrator (OMSA) 9.3.0 is also installed:
  • Tasks failing/timing-out on the host such as vMotion, snapshots, maintenance-mode, vm-power-on
  • Host disconnects from vCenter when you start one of the above tasks
  • ESXi Embedded Host Client is not accessible
  • esxcli commands are unresponsive.
If VMware ESXi 6.7 Update 2 is installed with OMSA 9.3.0, the service fails to start preventing any OMSA connectivity or monitoring functionality but the ESXi client is still fully accessible.

The failing OMSA service may also affect other management providers that load under ESX's CIM Server service. This includes Dell EMC iDRAC Service Module (iSM) which will lose functionality and iDRAC status will then identify the iSM service as not running.

The following event may be noted in the main ESXi syslog:

sfcb-dcim[2235472]: doLoadProvider: dlopen(/usr/lib/cim/ failed, dlerror: cannot open shared object file: No such file or directory


Dell OpenManage Server Administrator 9.3.0 that is released before ESXi 6.7 Update 2 or Update 3 were released and is therefore unsupported.



Dell EMC has since released OMSA 9.3.1 which supports ESXi 6.7 Update 3 and is available for download.
