#Maintenaces on the network ports for SG storage nodes

We have two maintenace tasks on the ports for some storage nodes. There are 4 ports already configured in LACP group on each node.

  1. Network Switch Upgrade. We need to connect cables from the old switch to the new switch. To do that, we are required to take a port down first in LACP, then take it up after the cable is connected to the new switch. How can I take the port down and then up?

  2. For some other storage nodes, there are only 2 connections in LACP group. We need to add two more. In order to be able to set up / configure the new ports that can be done by accessing SG Installer GUI, my understanding. However, after SG got depolyed, the GUI is no longer accessbile. Is there any way I can set up / configure ports then?

as for 1, you should just be able to simply unplug one of the LACP members without any interruption (that's what LACP is for after all)

#

if you re-plug it to the second switch you need to make sure the switches support some form of "cross-switch" link aggregation (like VCP on Cisco Nexus), otherwise you won't be able to get the fourth link back into the LACP team

  1. A big feature of LACP is you can take a port down with zero impact, so no need to take ports down first. As @old talon said, you need make sure your LACP can span both old and new switches or moving the links won't work.

  2. The steps are in the documentation. Its called Maintenance Mode, and takes the node back to the PGE (Pre Grid Environment ... aka, the installer).

Place Appliance into Maintenance Mode: https://docs.netapp.com/us-en/storagegrid-117/commonhardware/placing-appliance-into-maintenance-mode.html

Change SG5760 Link Configuration: https://docs.netapp.com/us-en/storagegrid-117/sg5700/changing-link-configuration-of-e5700sg-controller.html

There are pages for the other appliance models on the site too.

Place appliance into maintenance mode

You must place the appliance into maintenance mode before performing specific maintenance procedures.

Change link configuration of E5700SG controller

You can change the Ethernet link configuration of the E5700SG controller. You can change the port bond mode, the network bond mode, and the link speed.

Thank you for your messages.
To follow up my second question, instead of taking the node to the maintenance mode and then make the port configurations there, is there anyway I can use CLI's without taking it to the maintenance mode?

For the second question, you HAVE to use maintenance mode to change the network topology

As @heady frost said, no, you must do it from maintenance mode. You can change node interface IPs and routes from the Primary Admin Node with the "change-ip" tool via SSH, but other changes must be made in Maintenance Mode.
