Add and Manage a Flexible Disk Layout
Flexible disk layout enhances the storage flexibility and lets you add additional disks to a node. You can
also add the disks when you create an application blueprint. The disks are created dynamically during
provisioning and added to the node.
You can also manage placing the disks on different datastores. Once the user defines the flexible disk
layout for nodes in the blueprint, application deployer can further customize the deployment:
n
Map each individual disk to specific datastore
n
Set the disk size for each additional disk
The additional disks are part of virtual machine node. Both the service that uses the disks and the user
who uses the service, define the disks. Because of this, some assumptions are made between the
service and the user.
For example, If an Oracle service requires at least one data disk and one redo log disk to work, the user
must add two disks to the node else the service script does not run correctly.
Note You cannot specify different disk settings for an individual node in a same node array.
Databases can leverage flexible disk layout. The new Oracle 11g database service is added in Application
Services as out-of-the-box service. This service is modified to leverage flexible disk layout.
Prerequisites
Familiarize yourself with the predefined disk layout Info property when you plan to add multiple disks in a
virtual machine. See Predefined Disk Layout Info Property
Procedure
1 Select the node and click New on the Disks tab below the blueprint.
Consider the following options when you add a disk to your application blueprint:
Table 141. Disk Options
Option Description
Name The unique disk name within the node.
Mount Path The path for the disk to be mounted. Application Services does not mount the disk if the mount
path is not specified or if the disk is not formatted.
File System File systems such as ext3 or NTFS can be specified.
Size (GB) The size of the disk to be provisioned.
Tags A string specified that you can leverage to determine the mapping between disk and storage.
Description Specify more information for the disk.
