Leave the default values for the other fields.
Click Add Tag, Key: Name, Value: Provide the string that identifies this third service disk.
In the navigation pane, choose
Elastic Block Store.
Select an available volume and choose

For
Instance, start typing the name or ID of the instance. Select the instance from the list of options (only instances that are in the same Availability Zone as the volume are displayed).
For
Device, you can keep the suggested device name, or type a different supported device name. For more information, see
Name devices on Linux instances.
Choose
Attach.
For 7.6, the instance type should be m4.xlarge or m5.xlarge. If the instance type does not match, an alert is displayed. The recommendation is to use m5.xlarge.
Complete the following steps to resize DDMC instance if current instance type is not m5.xlarge.
Open the Amazon EC2 console, and in the navigation pane, choose
Instances.
Select the DDMC instance, and click
Actions > Instance state > Stop instance.
In the
Stop Instance dialog box, Click
Stop.
NOTE It can take a few minutes for the instance to stop.
Once the DDMC instance is in the stopped state, go to
Actions > Instance settings > Change instance type.
NOTE This action is unavailable if the instance state is not stopped.
In the
Change instance type dialog box, select the instance type, and click
Apply.
Go to
Instance state > Start instance to start the instance.
NOTE It can take a few minutes for the instance to enter the running state.
About this task
NOTE Software update files use the
.rpm file extension. This topic assumes that you are updating only DDMC. If you make hardware changes, such as adding, swapping, or moving interface cards, you must update the
DDOS configuration to correspond with the hardware changes.
Steps
Review the appropriate release notes for instructions for this update, and verifying available space.
NOTE For most releases, updates are permitted from up to two prior major release versions.
Click the
Settings button (the gear icon) in the DDMC banner, then select
System > UPDATE.
In the Update Packages Available area, select the update package from the list, and select
Perform System Update.
Monitor the update progress from the DDMC console page.
The update process automatically reboots DDMC.
It is recommended that you keep the System Update progress dialog open until the update completes, or until the system powers off.
Modifying the DDMC instance attribute to add the Elastic Network Adapter (ENA)
If the DDMC instance was manually deployed, the DDMC instance attribute must be modified to add the Elastic Network Adapter (ENA) support before changing the instance type to m5.xlarge.
Steps
Use the following AWS CLI command to check if current DDMC instance has ENA support.
In this example,
i-0bddc2cc1c9f9d61c is the instance id of DDMC instance. Use the instance id of the specific DDMC when running this command. If the result is
[] with vacant content, it means that the current DDMC instance does not support ENA.
After running the above command, use the following AWS CLI command to check if the ENA support attribute is in effect or not. If the result is
true, the DDMC instance should have the ENA support attribute and you can go to change the instance type to m5.xlarge.
