Migrate a VM between compute nodes

This section covers the procedure required to migrate a VM from one compute node to another compute
node.
Execution: Web Portal only
Procedure performed by: Solution administrator, or remotely by ThinkAgile Advantage Support (optional)
The compute node has no direct capability to migrate a VM between nodes, but you can use compute tags
for VM migration.
Compute tags allow the system to stick a VM based on compute tag requirements. If a VM has a tag, it can
only run on a compute node with this tag. When tags are added to VMs, the system automatically migrates
VMs to the proper compute node.
To move one VM to a specific compute node:
Step 1. Add a new compute tag to the destination compute node. Do not reuse an existing tag. The best
practice is to either use a random number or something like "temp_migrate_host_1."
Step 2. Add the same tag to the VM you are migrating.
Step 3. Wait until the VM is running on the destination compute node. You can find the VMs running in a
specific compute node by going in the compute node from the Hardware page and clicking View
All in the Application Instances section.
Step 4. Remove the tag from the migrated VM.
Important: This removal must be done before proceeding to the next step.
Step 5. Remove the tag from the compute node.

Compute block parts replacement procedures

Refer to Chapter 2 "Roles and responsibilities" on page 5 to determine who can perform these procedures.

Replace compute network cables

This section describes how to replace compute network cables.
Procedure performed by: Customer or field service
Replacing a cable that connects the compute enclosure to an interconnect can be done live, without any
specific preparation steps.
When a cable is disconnected, the compute node associated with the port decreases in bandwidth by 50%.

Remove a compute node

This procedure describes how to remove a compute node from your ThinkAgile CP configuration.
Procedure performed by: Solution administrator, ThinkAgile Advantage Support
To remove a compute node from your ThinkAgile CP configuration, perform the following steps:
Step 1. Obtain the serial number from the web portal's Hardware page.
Note: This step requires administrator-level access.
