Products

• VMware vCenter Server

Issue/Introduction

FDM configuration is moved to Configstore from vCenter 8.0.2 onwards. When the vCenter is 8.0.2 and above, the following changes are seen based on the underlying ESXi host versions.

Environment

VMware vCenter Server 8.0.2

Resolution

• Following are the ways to read FDM configuration.

1. On host above 7.0.3

Below command to read the FDM running  configuration from host 7.0.3 and above, when the managing vCenter is 8.0.2 and above:
/bin/configstorecli config current  get -c ha -k fdm_service -g cluster

Below command to read the FDM default  configuration from host 7.0.3 and above, when the managing vCenter is 8.0.2 and above:
/bin/configstorecli config default  get -c ha -k fdm_service -g cluster

P.S:  The  file /etc/opt/vmware/fdm/fdm.cfg is non-operative from the running FDM agent perspective and should not be read.

2. On host from 7.0.0 to 7.0.2

Below command to read the FDM running  configuration from host 7.0.0 to 7.0.2, when the managing vCenter is 8.0.2 and above:
/bin/configstorecli config current  get -c ha -k fdm -g cluster

Below command to read the FDM default  configuration from host 7.0.0 to 7.0.2, when the managing vCenter is 8.0.2 and above:
/bin/configstorecli config default  get -c ha -k fdm -g cluster

P.S:  This is to read only the customized FDM properties.  For reading infrastructure configuration i.e., the non-FDM properties open  the file /etc/opt/vmware/fdm/fdm.cfg

3. On host below 7.0

The  file /etc/opt/vmware/fdm/fdm.cfg is operative from the running FDM agent perspective and can be read by the user.

• Following are the ways to update  FDM configuration.

1. On host above 7.0.3

Below command to update  the FDM running  configuration from host 7.0.3 and above, when the managing vCenter is 8.0.2 and above. FDM agent be restarted to read the updated configuration:

$cat fdm.json
{
   "fdm": {
      "mem_reservation_MB": 200
   }
}
 $/bin/configstorecli config current  set -c ha -k fdm_service -g cluster --infile fdm.json

P.S:  The  file /etc/opt/vmware/fdm/fdm.cfg is non-operative from the running FDM agent perspective and should not be modified.

1.  On host from 7.0.0 to 7.0.2

Below command to update the FDM running  configuration from host 7.0.0 to 7.0.2, when the managing vCenter is 8.0.2 and above.
$cat fdm.json
{
   "mem_reservation_MB": 200
}
$/bin/configstorecli config current set -c ha -k fdm -g cluster --infile fdm.json

P.S:  This is to update  only the customized FDM properties.  For updating  the infrastructure configuration i.e., non-FDM properties modify  the file /etc/opt/vmware/fdm/fdm.cfg

1. On host below 7.0

The  file /etc/opt/vmware/fdm/fdm.cfg is operative from the running FDM agent perspective and can be modified by the user.
