Modify an SDS port during I/O

You can modify an SDS port while there is I/O running without interrupting I/O.

1. On the SDS, perform one of the following as appropriate for your operating system:

   Operating system	Task
   Linux	Run the script: /opt/emc/scaleio/sds/bin/close_firewall_port.sh
   Windows	From command line, run the batch file C:\Program Files\EMC\scaleio\sds\bin\close_firewall_port.bat

2. Open the following SDS file with a text editor, and change the port number shown there to the new port number:

   Operating System	File name
   Linux	/opt/emc/scaleio/sds/bin/port
   Windows	C:\Program Files\EMC\scaleio\sds\bin\port

3. Open the following SDS configuration file with a text editor:

   Operating System	File name
   Linux	/opt/emc/scaleio/sds/cfg/conf.txt
   Windows	C:\Program Files\EMC\scaleio\sds\cfg\conf.txt

4. Add the parameter tgt_port = <NEW_PORT_NUM> to the file, where <NEW_PORT_NUM> represents the new port number.
5. Run the script:
   /opt/emc/scaleio/sds/bin/open_firewall_port.sh
6. On the SDS, run the command:

   Pkill sds

7. On the MDM, modify the SDS port using the command:

   scli --modify_sds_port (--sds_id <ID> | --sds_name <NAME> | --sds_ip <IP>) --new_sds_port <PORT>

   For example, for an SDS called "sds198" where the new port number is 7071, type:

   scli --modify_sds_port --sds_name sds198 --new_sds_port 7071

   NOTE: If you modify the SDS port on the MDM first, instead of following the above procedure, I/O errors might be encountered.
