If the existing disks of a BMS fail to meet service requirements, for example, due to insufficient disk space or poor disk performance, you can attach more available disks to the BMS, or create more disks and attach them to the BMS.
Disks are available.
For details about how to create disks, see "Creating an EVS Disk" in Elastic Volume Service User Guide.
The page showing details of the BMS is displayed.
The Attach Disk dialog box is displayed.
If no EVS disks are available, click Create Disk in the lower part of the list.
For the restrictions on attaching disks, see What Are the Restrictions for Attaching a Disk to a BMS?
After the disk is attached, you can view the information about it on the Disks tab.
If the attached disk is newly created, the disk can be used only after it is initialized (formatted). For details about how to initialize data disks, see Initializing Data Disks.
After the BMS is restarted, the drive letter of the EVS disk may change. For the mapping between the EVS disk device and drive letter, see How Do I Obtain the Drive Letter of an EVS Disk?
