This document explains how to configure the <properties> element in vpcs.xml. Within the Manage Environment page, a user has the option to modify a VPC. The <properties> element contains all information necessary to modify a VPC and the reservations that exist on them. This element also establishes the rules for modifying configurable attributes of a VPC.

• Disk Model
• Fiscal Year End

The <bare-metal-variable> element is also a child element of the <properties> element. For more information, see Accessing Bare Metal Machines with Viewpoint.

To manage users in vpcs.xml, see Managing VPC Users. To configure generic reservation commands, see Generic Commands.

5.1.1.1 Disk Model

The <disk-model> element defines how disk operations should take place within Viewpoint. Viewpoint needs to know how the disk is configured in Moab so it knows how to perform operations on a reservation (such as adding or removing resources). To specify which type of disk is being used, use the type attribute. There are two valid disk storage types:

• "NODE_DISK" - Disk is stored on the individual nodes using the "disk" attribute in Moab. There is no global SAN disk usage.
• "GLOBAL_DISK" - Disk storage is on the GLOBAL node only and is accessed through a generic resource. In this model, all disk is accessed from a generic resource on the GLOBAL node and the individual reservations have a variable signifying how much disk they are consuming. This model requires two child elements:
  • <generic-resource> - An element that contains the name of the generic resource on the GLOBAL node.
  • <variable> - An element that contains the variable name stored on each reservation that informs Moab and Viewpoint how much disk the individual reservation is using. With this model, any given VPC contains one additional, hidden reservation that contains only the disk storage.

To set up a SAN disk model where the generic resource is called "SAN" and the variable on each reservation is called "VM_SAN", you can follow this example:

<disk-model type="GLOBAL_DISK">
 <generic-resource>SAN</generic-resource>
 <variable>VM_SAN</variable>
</disk-model>

5.1.1.2 Fiscal Year End

This is no longer supported. If you have used this element in your vpcs.xml file, please go to Converting From <fiscal-year-end> to New Components Framework.
