Description

The Migrate Storage feature lets you perform simple field upgrades of the storage array of any upgradeable Datto device. You can also replace hard drives that are in a pre-failure state.

Warnings

  • The Migrate Storage tool cannot detect drives that are in a complete failure state - if the drive you are replacing is in this state, contact Datto Technical Support for assistance.
  • Virtual Datto appliances are unsupported.
  • You will need available bays to accommodate the additional, or replacement drives you wish to install. If you need to replace a failing drive and do not have any free bays, contact Datto Technical Support for assistance.
  • If upgrading storage, the Datto appliance will set a quota that caps the usable storage based on the billing tier it detects. If a device billed for 4 TB of storage is upgraded using 8 TB drives, the device will only allow 4 TB of storage. Contact your Datto Sales Executive before upgrading storage to ensure that your device's service plan is sufficient for the amount of storage you want.
  • The Supermicro SAS card (AOC-SAS2LP-MV8) installed in SIRIS units manufactured before April 1, 2015, is incompatible with 3 TB drives. If your Datto appliance contains this card, contact your Datto Sales Executive for assistance with obtaining a replacement controller before installing any 3 TB drives.

Overview

To get to the Migrate Storage page, navigate to the Advanced Device Status page in the Datto appliance GUI. In the Storage Upgrade and Repair category, click Manage Storage,

Figure 1: Storage Upgrade and Repair → Manage Storage (click to enlarge)

Figure 2: Migrate Storage page (click to enlarge)

You will see the following information listed.

1. Available Destinations: This field displays a list of the hard drives currently detected by the Datto appliance, along with the following information:

  • Name: Displays the Linux drive letter assigned to each drive during the most recent boot. These drive letters may change each time the device boots.
  • Status: Indicates which drives are already part of the device's homePool configuration (listed as Active) and which are new.
  • Model: Lists the detected model of the available drives.
  • Drive Size: Lists the raw drive size of each drive.
  • Serial: Lists the detected serial numbers of the available drives.
  • Health: Provides an assessment of each drive's health, as determined by SMART error reporting.

2. Refresh: Refreshes the list of available hard drives.
3. Blink Drive LEDs: If your Datto appliance has hot-swappable hard drives, clicking this button will cause the orange activity light on the hard drive bay of the selected drive(s) to illuminate solidly for 10 seconds.
4. Migration Configuration: Allows an operator to specify the type of operation to perform. The options are:

  • Replace Drive(s): 
    • Use this option if you need to replace an Active drive with a New drive in a scenario where you will be removing old drives (for example, when replacing a 1 TB drive with a 2 TB drive, or when you are replacing a drive in a pre-failure state). You will need to have available bays to accommodate the replacement drives as the old drives cannot be removed until the migration is complete.
  • Add ... to homePool Array [Mirror/RAID 1, Parity/RAID 5, Parity/RAID 6]: 
    • For use on SIRIS Imaged devices only. This option allows you to expand redundancy of the array on the Datto appliance when you will not be removing the old drives, or as directed by Technical Support. You will need to have available bays to accommodate the additional drives.

5. Migration Options: You can suspend activity on the Datto appliance during the migration (recommended), or schedule a future time for the migration to take place. The available options are:

  • Temporarily Enter Maintenance Mode: Suspends all backup and screenshot activity on the Datto appliance during the migration.
  • Schedule Migration: Lets you schedule the migration for a future date and time. Selecting this option will display a banner in the Datto appliance GUI reminding you that a migration is scheduled.

Procedures

Replacing drives

Before attempting any field upgrade by using the Replace function, review this matrix for a list of the types of storage upgrades a Datto device operator can perform in the field.

1. Navigate to the Advanced Device Status page in the Datto appliance GUI. In the Storage Upgrade and Repair category, click Manage Storage.

2. Make sure that the replacement drive is inserted and listed as New and in good health. From the drives listed at the top of the page, select the Active drive you want to replace and the New drive you want to replace it with. Do not remove the old drives until the migration completes.

3. Under Migration Configuration, select Replace Drives.

4. Under Migration Options choose Temporarily enter maintenance mode (recommended).

5. Click Next. You will see the Review & Confirm screen. Click Previous if you need to make changes to the migration configuration. Otherwise, click Migrate Now.

One the migration is underway, you will be returned to the Device Overview page. When the migration completes, you will see a green banner with the message "A migration completed successfully." The Datto appliance will resume normal activity.

Adding drives

Contact Datto Technical Support for guidance before attempting to expand the array or reconfigure the RAID configuration on any Datto appliance.

1. Insert the additional drives.

2. Navigate to the Advanced Device Status page in the Datto appliance GUI. In the Storage Upgrade and Repair category, click Manage Storage.

3. Under Migration Configuration, select all of the New drives to add to the Active array configuration, and then select the desired RAID configuration. The Datto appliance will only allow you to select a compatible RAID configuration.

4. Under Migration Options choose Temporarily enter maintenance mode (recommended).

5. Click Next. You will see the Review & Confirm screen. Click Previous if you need to make changes to the migration configuration. Otherwise, click Migrate Now.

Once the migration is underway

You will be returned to the Device Overview page. When the migration completes, you will see a green banner with the message "A migration completed successfully." The Datto appliance will resume normal activity.

 Notes

  • If you schedule the migration for a future date, you will see a reminder that includes the date and time of the migration displayed at the top of the page.
  • If you choose to Migrate Now, you will see a banner advising that the migration is in progress. The Maintenance Mode banner will also appear unless you disabled the Temporarily Enter Maintenance Mode feature and the running migration will appear on the Storage Upgrade and Repair card of the Advanced Device Status page.

Next Steps

  • If you upgraded storage, to begin using your new storage space, contact Datto Technical Support to have your appliance's upgraded model information updated in the cloud database.
  • If you replaced drives, it is now safe to remove the old drives.
