If you are instructed to create a key pair for troubleshooting a failure that occurs when adding storage nodes, perform the following procedure to create a key pair and register it to Parameter Store.

Note on the procedure

In the following procedure, long command lines begin on a new line delimited by "\."

If a key pair having the following name exists in the list of key pairs of the AWS Management Console, delete the key pair. If such a key pair does not exist, go to step 2.
Key pair name: <stack-name-at-the-time-of-installation>-KeyPair
```
aws ec2 delete-key-pair --key-name \
<stack-name-at-the-time-of-installation>-KeyPair
```

Create a new key pair.

aws ec2 create-key-pair --key-name \
<stack-name-at-the-time-of-installation>-KeyPair \
--key-type rsa --key-format pem --query "KeyMaterial" \
--output text > <stack-name-at-the-time-of-installation>-KeyPair.pem

Obtain the ID of the key pair you created in step 2.

aws ec2 describe-key-pairs --key-names \
"<stack-name-at-the-time-of-installation>-KeyPair" \
--query "KeyPairs[0].KeyPairId" --output text

aws ssm put-parameter --name \
"/ec2/keypair/<ID-of-key-pair-confirmed-in-step-3>" --type "SecureString" \
--value "$(cat <stack-name-at-the-time-of-installation>-KeyPair.pem)"

Delete the key pair from the controller node.
```
rm -i <stack-name-at-the-time-of-installation>-KeyPair.pem
```
You can run the command to verify whether the file to be deleted is correct. If the file is correct, delete it.
