The vmware update manager logfile (C:\ProgramData\VMware\VMware Update Manager\Logs) may show the error “Could not find a trusted signer”
This can be resolved by removing the Dell VIBs for OpenManage and the Equallogic Multipath Module and reinstalling manually
esxcli software vib remove -n OpenManage -n dell-configuration-vib -n dell-eql-host-connection-mgr -n dell-eql-hostprofile -n dell-eql-routed-psp
Manually re-install the OpenManage VIB
esxcli software vib install -d /tmp/OM-SrvAdmin-Dell-Web-7.2.0-6945.VIB-ESX51i.zip
Reboot the host to remove the loaded VIBs from memory and load the new version of OpenManage
The equallogic module can be reinstalled with Update Manager with no reboot required
