Data Transport:Upload data to the cloud and verify the migration

Prerequisites

All data has been migrated to the Data Transport III device. The migration task is stopped and the device is powered off.

Return the device

1. Confirm the task status

Run the following commands in sequence. Confirm that the task status is succeeded and that the data passes CRC-64 verification against the source files.

• Run the cdmgwclient command to enter the directory.

• Run the bash console.sh status <job_name> command to view the task status. Replace <job_name> with the actual job name.

2. Stop the migration service

Run the following command to stop the migration service.

• beforepoweroff

3. Uninstall and lock the storage pool

Run the following command to uninstall and lock the storage pool.

• crypt close

4. Power off the device

Run the poweroff command to power off the device.

5. Check the accessories

1. Confirm that the four optical transceiver modules are present on the 25G optical port.

2. Confirm that both power cables are present.

3. Hand over the Data Transport device to the Alibaba Cloud logistics partner.

Upload data to the cloud and verify the migration result

Grant permissions to a RAM role

Alibaba Cloud uses a specific RAM role to upload data from the Data Transport device to your specified Object Storage Service (OSS) bucket. You must grant the required permissions to the RAM role. The procedure is as follows:

• Log on to the OSS console.

• In the navigation pane on the left, click Buckets and select the destination bucket.

• In the navigation pane on the left, choose Access Control > Bucket Policy.

• On the Add by Syntax tab, add a custom bucket policy. Then, click Edit and Save.

  • The policy must grant the RAM role permissions to list, read, delete, and write all resources in the bucket.

  "Version": "1",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "oss:List*",
        "oss:Get*",
        "oss:Put*",
        "oss:AbortMultipartUpload"
      ],
      "Principal": [
         "arn:sts::1737441177608761:assumed-role/mgw-data-transport-role/*"
      ],
      "Resource": [
        "acs:oss:*:<myuid>:<mybucket>",
        "acs:oss:*:<myuid>:<mybucket>/*"
      ]
    }
  ]
}

Upload data to the cloud

Alibaba Cloud personnel use the authorized RAM role to upload the data from the Data Transport device to the cloud. After the data upload is complete, they contact you and provide a migration report. You can use the report to verify the migration result. This completes the migration task.

Migration report

After a migration report is generated, it is stored in your specified OSS bucket. The report files are located in the following paths:

OSS://<bucket>/<prefix>/aliyun_import_report/<uid>/<jobid>/<runtimeid>/total_list/
OSS://<bucket>/<prefix>/aliyun_import_report/<uid>/<jobid>/<runtimeid>/failed_list/
OSS://<bucket>/<prefix>/aliyun_import_report/<uid>/<jobid>/<runtimeid>/skipped_list/

Verify the migration result

Data Transport is responsible only for data migration and does not guarantee data consistency or integrity. After the migration task is complete, you must verify all migrated data by performing data consistency verification between the source and destination. After the migration is complete, promptly revoke the authorization of the specific Data Transport RAM role.
