Adding and Removing Disks for Your Gateway

You can add or remove underlying disks from your gateway as described following. For example, you might add disks to your gateway to use as an upload buffer or cache storage if you need additional upload buffer space or cache storage. You can also remove the underlying disks from your gateway. For example, you might want to remove a failed disk from your gateway.

Important

When adding cache or upload buffer to an existing gateway, it is important to create new disks in your host (hypervisor or Amazon EC2 instance). Don't change the size of existing disks if the disks have been previously allocated as either a cache or upload buffer.

Remove a Disk from a Gateway Hosted on VMware ESXi

You can use the following procedure to remove a disk from your gateway hosted on VMware hypervisor.

To remove a disk allocated for the upload buffer (VMware ESXi)

  1. In the vSphere client, open the context (right-click) menu, choose the name of your gateway VM, and then choose Edit Settings.

  2. On the Hardware tab of the Virtual Machine Properties dialog box, select the disk allocated as upload buffer space, and then choose Remove.

    Verify that the Virtual Device Node value in the Virtual Machine Properties dialog box has the same value that you noted previously. Doing this helps ensure that you remove the correct disk.

Remove a Disk from Gateway Hosted on Microsoft Hyper-V

Using the following procedure, you can remove a disk from your gateway hosted on a Microsoft Hyper-V hypervisor.

To remove an underlying disk allocated for the upload buffer (Microsoft Hyper-V)

  1. In the Microsoft Hyper-V Manager, open the context (right-click) menu, choose the name of your gateway VM, and then choose Settings.

  2. In the Hardware list of the Settings dialog box, select the disk to remove, and then choose Remove.

    The disks you add to a gateway appear under the SCSI Controller entry in the Hardware list. Verify that the Controller and Location value are the same value that you noted previously. Doing this helps ensure that you remove the correct disk.

    The first SCSI controller displayed in the Microsoft Hyper-V Manager is controller 0.

  3. Choose OK to apply the change.
