How to add SDS?
Please let us know how to add an another disk of a server which is configuring a ScaleIO environment, as SDS device?
There is a configuration that is using the server A's E drive as a SDS device of ScaleIO.
To this configuration, we want to newly add the server A's F drive as a SDS device.
We would like to ask you to make clear for us the procedure.
Actually, we failed after trying to do the following:
---
We modified the script relating to the CSV's server A during the installation as shown below:
Set " sds1" to [SDS Name] --> "sds1" has not been changed.
Set "E,F" to [SDS Device List] --> "E" has been changed to "E,F"
Set " sds_dev1,sds_dev4" to [SDS Device Names] --> "sds_dev1" has been changed to "sds_dev1,sds_dev4"
We were expecting the SDS configuration would be:
SDS Name：sds1 100GB
|-- SDS Device：sds_dev1(E) 100GB
↓
SDS Name：sds1 200GB
|-- SDS Device：sds_dev1(E) 100GB
-- SDS Device：sds_dev4(F) 100GB
We have performed the configuration change from the Install Manager.
However, we found the sds1 capacity was not changed (compared to the capacity before the configuration change) and it was remained as 100GB, even after completing all the phases.

You cannot use the IM to add additional SDS devices to an already configured SDS. IM can be used to Extend the system with additional new SDSs.
In order to add devices to existing SDS you can use one of the following options:
1. Use the CLI: scli --add_sds_device (scli usage is clear enough) -> note that device 'F' needs to be online not formatted, with no partitions on it. You can also add it as physical Drive X, not a must to use drive letters.
2. Use the ScaleIO GUI: Backend view -> select that SDS -> right-click -> add SDS device -> fill in the required fields.
3. Using REST-API (cURL)
(you can find full instructions for each of the options in the user guide)

To add an sds device, use the cli on the primary mdm server:
scli --add_sds_device --sds_ip --storage_pool_name --device_path F --device_name sds_dev4
This command adds a device to the devices managed by the given SDS.
Please note this command destroys all existing data on the device.
Then run a #scli --query_all_sds to view the added SDSs
