Dell PowerFlex v3.6.x CLI Reference Guide

modify_management_ip

Modify an MDM node’s management IP addresses.

If you are using this command to add additional management IP addresses, you must enter all of the existing IP addresses in the command, and add the new ones at the end. Up to four IP addresses are supported.

Syntax

scli --modify_management_ip (--new_mdm_management_ip <IP> | --clear_all) (--target_mdm_id <ID> | --target_mdm_ip <IP> [--target_mdm_port <PORT>] | --target_mdm_name <NAME>) 
  [--allow_duplicate_management_ips]
  [--i_am_sure]

Parameters

--new_mdm_management_ip <IP>: Comma-separated list of IP address to be used to manage the MDM. Omit the space after each comma.
--clear_all: Clear all management IP addresses.
--target_mdm_id <ID>: MDM ID
--target_mdm_ip <IP>: MDM IP address
--target_mdm_port <PORT>: MDM port
--target_mdm_name <NAME>: MDM name
--allow_duplicate_management_ips: Allow duplicate management IP addresses.
--i_am_sure: Skip the safety questions for command execution. (For example: “This could damage the stored data. Are you sure?”)

Example

scli --modify_management_ip --target_mdm_id 0x34e8f1df6c84a410 --new_mdm_management_ip fd00::192:168:1:17,10.103.110.17

Implementing the changes

After modifying MDM IP addresses, ensure that you implement the change in all components and interfaces that are mapped to the MDM:

PowerFlex GUI: In the Login window, log in using the new IP address, then clear the old IP address from the history if it is now obsolete.
REST Gateway and OpenStack: In the REST Gateway, modify the mapping to the new management IP address.
On each SDC, perform the following locally, in command line with root access permissions:
- If for any reason, the management IP address is not updated in the SDC, run:
```
 /opt/emc/scaleio/sdc/bin/drv_cfg --mod_mdm_ip
```
- If the SDC is mapped to more than one PowerFlex system, run:
```
/opt/emc/scaleio/sdc/bin/drv_cfg --add_mdm
```
vSphere: Using the vSphere web plug-in interface, unregister PowerFlex and reregister it with the new IP address.
