Dell EMC PowerProtect DDVE on Amazon Web Services 7.9 Installation and Administration Guide

Adding more metadata disks for the DDVE instance

If required, more metadata disks can be added to the DDVE instance from the AWS console.

1. Log in to the AWS console.
2. Select EC2 dashboard under services. Navigate to the Elastic Block Store pane and click Volumes.
3. Provide the following details. Then click Create Volume.
   • Volume Type: Select GP3.
   • Size (GiB): Select 1024 for 16/32/96 TB DDVE instance and 2048 for 256 TB DDVE instance.
   • IOPS: Set 3000
   • Throughput MB/s: Set 125
   • Availability Zone (AZ): Choose the same AZ in which the DDVE instance is deployed.
   • Name Tag: Add a name tag for the volume to filter it in searches.
   Leave Snapshot ID blank.
   
4. In the Volumes tab, enter the name tag (created in previous step) for the volume. Select the volume, click Actions, and select Attach Volume.
   
5. In the attach volume window, enter the instance ID and device name:
   • Instance: Enter the name/instance ID of the DDVE instance, and select the correct instance from the list of instance options.
   • Device: Based on the instance, a default device name is automatically populated in this field. The device names for existing volumes on this instance can be /dev/sd* or /dev/xvd*. Ensure that the new volume being attached follows the device naming convention for other metadata disks on this instance.
   
   NOTE You can check the device names for an instance by selecting an instance in the EC2 dashboard and viewing the block device names for its EBS volumes:

   
6. To create and attach additional metadata disks to the DDVE instance, repeat steps 2 to 5.
7. To configure the metadata storage using CLI or DDSM, log in to the DDVE instance.
   Using CLI:

   • Run the disk show hardware command to verify that the new metadata disk or disks are successfully added to the DDVE instance.
   • Run the storage add dev<n> command to add the new metadata disk or disks to the active tier.
   • Run the filesys expand to make the newly added metadata disk or disks available to the filesystem.
   Using DDSM:
   Alternatively, you can configure the storage using DDSM. Click Hardware > Storage > Configure Storage.
   NOTE Do not manually configure spindle groups. Spindle group configuration occurs automatically.
