The General tab describes the appliance class as a whole and also contains some advanced settings.
Class name. Defines the name of the appliance class. This name is shown in the bottom left side of each appliance shape on the canvas. If the appliance is placed in a catalog, the class name is also shown in the catalog. The name is a single word, case-sensitive, alphanumeric ([A-Za-z0-9_]).
Template from which appliance instance names are generated. When a template is specified, the first instance will have the same name as the template and subsequent instances will have names comprised of the template followed by a number. If no template is specified, the name of the class is used as the template.
Category of the appliance. The category is a short alphanumeric phrase describing the group (category) of appliances within a catalog that the appliance belongs to. If the appliance is placed in a catalog, all appliances from the same category are grouped together in a section.
Free text description of the appliance. Typically the description contains definition of the appliance's function, some distinguishing details (separating an appliance from other similar appliances), and the key software package(s) used inside the appliance.
Specifies the URL where the class documentation can be found.
The following attributes determine the visual appearance of the appliance shape:
The color of the appliance shape, as shown on the canvas and in the catalog.
The width of the appliance shape when shown on the canvas.
The OS icon shown on the appliance shape, as shown on the canvas and in the catalog.
Note:
The following attributes determine special and diagnostic features for the appliance class.
Specifies the type of virtualization to use for the appliance. CA AppLogic® supports the following virtualization modes:
The default value of the boot timeout for the appliance -- the time, in seconds, that CA AppLogic® allows the appliance between the start of boot and the moment the appliance needs to indicate to CA AppLogic® that it has completed boot and is operational. See the Grid User Guide for details. We recommend that you leave this setting empty to allow use of the systemwide default timeout.
The default value of the shutdown timeout for the appliance -- the time, in seconds, that CA AppLogic® allows the appliance between the start of shutdown and the moment the appliance needs to indicate to CA AppLogic® that it has shutdown. We recommend that you leave this setting empty to allow use of the systemwide default timeout.
This is a numeric value that enables diagnostic or other special features of CA AppLogic® for the appliance class; this setting affects all instances of the appliance. Do not enable this option unless directed by a support engineer.
Comma-separated list of name=value pairs that can be used for billing purposes. Please do not use; reserved for future use.
The following advanced settings are available by clicking on the Advanced button when the virtualization mode is set to paravirtualization:
Path to the file containing the OS kernel on the appliance boot volume. The path is relative to the boot volume root directory. If a kernel path is not specified, the appliance uses pygrub to start. See the Grid User Guide for more details on choosing the correct kernel.
Path to the file containing the boot initrd image on the appliance boot volume. This path is relative to the boot volume root directory. If an initrd path is not specified, the appliance uses pygrub to start. See the Grid User Guide for more details on choosing the correct initrd image.
Specifies the types of consoles that are supported by the appliance. The value of this setting is a comma-separated list of one or more of the following:
Additional parameters to be specified on the kernel command line when the appliance boots. This setting can be used to pass parameters to high-level drivers running in the appliance, such as file systems and network stacks. For Linux appliances, the kernel command line syntax is space-separated param=value pairs. This setting is optional and is usually empty.
Specifies the schema by which the appliance operating system recognizes disk devices. For example, Linux recognizes disk devices as /dev/hda1, /dev/hda2 ... /dev/hdaX. The device schema is used by CA AppLogic® to auto-assign devices to new volumes that are added to the appliance class. The devices are stored in the class descriptor and can be used by the appliance to access its volumes. The following device schema are supported:
Specifies the mechanism by which the appliance retrieves its configuration. The following mechanisms are supported:
The following advanced settings are available by clicking on the Advanced button when the virtualization mode is set to hardware Emulation:
Specifies the types of consoles that are supported by the appliance. The value of this setting is a comma-separated list of one or more of the following:
This setting is only available when the virtualization mode is set to Hardware Emulation and consists of a space separated list of options in the format of option=val that affect how the appliance is started. The following options are supported:
Specifies the schema by which the appliance operating system recognizes disk devices. For Hardware Emulated appliances, this setting must be set to hda,hdb,hdc,hdd. The device schema is used by CA AppLogic® to auto-assign devices to new volumes that are added to the appliance class. The devices are stored in the class descriptor and can be used by the appliance to access the volumes.
Specifies the mechanism by which the appliance retrieves its configuration. For Hardware Emulated appliances, this setting must be set to dhcp and the appliance must have the CA AppLogic® Appliance Kit (APK) installed. See the APK User Guide for more information.
