We have recently started testing this extension to run driver and firmware upgrades from within WAC. Each time we schedule a firmware run, it fails to Suspend Server, even after proving we can drain all hosts in the cluster manually via the cluster manager. It will fail at this step regardless of the firmware selected or the hosts/hosts selected.
Interestingly, if we manually pause the host before the update run is scheduled, it will get passed the Suspend Server task and continue on with the firmware install process successfully. We haven't been able to find any information in the logs of the Integrator, on XClarity Administrator directly, in the Hyper-V and FOCM logs or the Cluster logs.
If anyone has come across this before or could help that would be much appreciated.
