Enabling DAOS tier 2 storage

After you configure the credential store, enable DAOS tier 2 storage on Domino servers.

Procedure

Steps for MinIO storage service only:
1. Add the following notes.ini setting on the server: S3_USE_MINIO=1
2. Do one of the following:
  - To use secure connections over HTTPS, load the SSL certificate to AWS, following instructions in the MinIO documentation. If the certificate is self-signed, add the following notes.ini setting to the Domino server: COS_SKIP_SSL_VERIFY=1.
  - To use HTTP instead, add the following notes.ini setting to the Domino server: COS_USE_HTTP=1.
Complete the following steps to enable DAOS tier 2 storage on a Domino server:
1. Open the Server document in the Domino® directory in edit mode.
  Note:
  - If you manage the Domino directory on the Domino administration server, set up the administration server to use the credential store, including creating a replica of the credential store on the administration server. For more information, see Configuring a credential store for DAOS tier 2 storage.
  - If you do not manage the Domino directory on the Domino administration server, make sure that the changes you make in this step replicate to the administration server.
2. Click the DAOS tab and refer to the Tier 2 Storage section of the document.
3. In the DAOS Tier 2 field, select Enable.
4. In the S3 Credential Name field, select the credential name from the Domino® credential store to use to connect to the storage service specifed in Step 5 of the procedure Configuring a credential store for DAOS tier 2 storage. For example, dominocos.
5. In the S3 Bucket field, enter the name of the bucket created in Step 2 of the procedure Configuring a credential store for DAOS tier 2 storage, for example, aws-hcl-dominocos.
6. In the S3 Endpoint field, enter the endpoint to use to connect to the object storage service specified in Step 2 of the procedure Configuring a credential store for DAOS tier 2 storage. It can be a known endpoint or a URL with a port number. Examples:
  - AWS: us-east-1
  - MinIO instance on local server over HTTPS: minio.myserver.renovations.com
  - MinIO instance on local server over HTTP (port number required): minio.myserver.renovations.com:9000.
7. In the Push object to store if not accessed for field, enter the number of days an attachment is not accessed for it to be put in tier 2 storage. Default is 1000 days.
8. Save your changes.
Restart the Domino server:
```
restart server
```

What to do next

The server tests the DAOS tier 2 configuration. If the test is successful, the following output is shown at the server console:

AWS:AWSSelfTest: Success. AWS connection for DAOS is up and running.

If the test is not successful, the console shows an AWS:ProcessError error. For example, if the bucket name is incorrect, the following error is shown:

AWS:ProcessError: 131  Exception NoSuchBucket: The specified bucket does not exist
