Roles and responsibilities

This section covers information about the roles and responsibilities involved in the replacement of different ThinkAgile CP hardware components.

Each maintenance and replacement procedure in this guide is performed by one or a combination of the following actors:

• Solution administrator: May be customer, third party, or whoever has access to the solution for performing administrative procedures (Cloud Controller, infrastructure)

• Customer or field service: For physical replacement of CRUs/FRUs based on part type and entitlement level

• Lenovo Support: Works with solution administrator to perform remote support procedures

The following table illustrates which roles are responsible for each of the tasks in this guide. Some tasks can be completed by the customer alone, while other tasks require the participation of Lenovo Support.

Task	Actor
	Solution administrator	Customer or field service	Lenovo Support
Shutting off a compute node	Shuts down compute node on Cloud Controller web portal
Migrating VMs from a compute node	Turns on Maintenance Mode Uses Migrate tool OR Enables Support Mode for ThinkAgile Advantage Support assistance		Optional. If customer wants assistance: Accesses node remotely via Support Mode Turns on Maintenance Mode Uses Migrate tool
Migrate a VM between compute nodes	Adds and removes compute tags to destination compute node and VMs OR (Optional) Enables Support Mode for ThinkAgile Advantage Support assistance		Optional. If customer wants assistance: Accesses node remotely via Support Mode Adds and removes compute tags to destination compute node and VMs
Replace compute network cables		Physically replaces compute enclosure-to-interconnect cable
Remove a compute node	Shuts down and removes compute node Enables Support Mode on interconnect		Signs into primary interconnect via Support Mode Runs commands and gathers info Requests hardware removal

Shutting off a storage controller	Physically connects to storage controller Enters shutdown commands in hardware console OR (Optional) Enables Support Mode for ThinkAgile Advantage Support assistance		Optional. If customer wants assistance: Accesses storage controller remotely via Support Mode Enters shutdown commands in hardware console
Trigger manual storage HA	Connects via SSH to active storage controller Runs command to stop storage controller services OR (Optional) Enables Support Mode for ThinkAgile Advantage Support assistance		Optional. If customer wants assistance: Accesses storage controller remotely via Support Mode Runs command to stop storage controller services
Shutting down the storage block	Powers off the storage block (all storage controllers) in the Cloud Controller
Replacing storage network cables or transceivers		Physically replaces storage controller-to-interconnect cable or transceiver
Remove a hot-swap storage controller	Obtains serial number of storage controller to be removed Shuts off storage controller Physically removes storage controller from rack Enables Support Mode		Signs into primary interconnect Runs command and gathers information Contacts LenovoSupport and requests hardware removal
Install a hot-swap storage controller	Physically installs and powers on storage controller Enables Support Mode		Updates the storage node VPD Signs into primary interconnect and runs command Registers storage blocks
