2. Select the desired instance.On the lower half of the window, detailed information about the selected instance is displayed.

   Info
   title Note
   If you are creating volumes in context of AWS Volume-based Upgrade - 5.1.0Sxxx to 6.2.1, the volumes created using a 6.2.1R000 AMI snapshot must be in the same "Availability zone" as that of the 5.1.0Sxxx instances. Ensure to select an instance that is in the same "Availability zone" as that of the 5.1.0Sxxx instances that you want to use for volume-based upgrade.

   Info
   title Note
   If you are creating the volume in context of AWS Volume-based Upgrade - 5.1.0Sxxx to 6.2.1, you must modify the value of the field Volume Type to match the volume types of the 5.1.0Sxxx instances. If the volume is standalone, you may modify the value based on your requirement. Note that the value of the field IOPS changes automatically, based on your selection of Volume Type. For a volume based on a 6.2.1 AMI ID, the value of the field Size must be equal to or greater than 65. If you are creating the volume in context of AWS Volume-based Upgrade - 5.1.0Sxxx to 6.2.1, the value of the field Availability zone must match with the "Availability zone" of the 5.1.0Sxxx instances. If the volume is intended to be used as standalone, do not check the checkbox adjacent to the Tag field - it is not necessary to create additional tags.

6. Optional (if the volume is intended to be part of an HA pair) - If you want to easily distinguish the active and standby volumes, check the checkbox adjacent to the Tag field and add appropriate key-value pairs, as illustrated in the above image.

7. After all necessary modifications, click Create Volume. A success message is displayed.
