Loading a configuration file using drv_cfg

This utility reads a configuration file containing MDM IP addresses, and calls the kernel to connect to them.

Location of drv_cfg command:

  • Linux: /opt/emc/scaleio/sdc/bin/drv_cfg
  • Windows: C:\Program Files\emc\scaleio\sdc\bin\drv_cfg
  • ESXi: Refer to "Update the SDC parameters in VMware based HCI or Compute node".

The configuration file that is loaded when using the drv_cfg --load_cfg_file utility is not persistent; when you restart the SDC, the changes will be lost.

To make the changes persistent, perform either of the following:

  • Install the SDC on every server that exposes volumes to the application running, by running the following command: 
    MDM_IP=<IP of the MDM> rpm –i <full rpm file path>
  • Use the following drv_cfg command: 
    /opt/emc/scaleio/sdc/bin/drv_cfg --mod_mdm_ip
--ip <EXISTING_MDM_IP_ADDRESS> --new_mdm_ip
<NEW_MDM_IP_ADDRESSES>
