Add Resource Group Wizard - Tape

Use this page to define and configure one or more shared tape resources for the resource group.

You can configure a SCSI or a Fibre Channel tape drive as a cluster resource in a non-concurrent resource group, making it highly available to all nodes defined for the resource group that is managing the tape device.

All fields on this page are inactive until you specify information for the Tape Name field, then all fields are enabled.

Fields

Tape name
Select a predefined tape device from the provided list or manually specify a unique name for a custom tape device that you want to define for the resource group. The name you specify must consist of a minimum of one alphanumeric character and a maximum of 64 alphanumeric characters. You can use alphabetic characters of A - Z and a - z, numbers of 0 - 9, as well as underscore (_) characters. A name cannot begin with a number and cannot be a PowerHA™ reserved word.

If you choose a predefined tape device, the Tape device, the Start script, and Stop script for it are also predefined, and these fields are completed for you and you cannot change them.

Tape device
Specify the path and file name of the tape special file. If the first character is not a forward slash (/), /dev/ is prepended to the path that you specify.
Start script
Specify the full path and file name of the program to be used to start the tape device, along with any additional arguments to be passed to the program when it runs. This program is run whenever the required resources become available, such as when a node joins the cluster. You can use a maximum of 256 alphanumeric characters. This script must be in the same location on each cluster node that might start the server. The contents of the script, however, can differ.
Start processing synchronously
Select whether to start processing the start script synchronously. The default value is Yes.
Stop script
Specify the full path and file name of the program to be used to stop the tape device, along with any additional arguments to be passed to the program when it runs. This program is run whenever the required resources become available, such as when a node joins the cluster. You can use a maximum of 256 alphanumeric characters. This script must be in the same location on each cluster node that might start the server. The contents of the script, however, can differ.
Start processing synchronously
Select whether to start processing the start script synchronously. The default value is Yes.

Actions

Add Another
Click Add Another to add another set of fields so that you can create and configure another tape device for your custom resource group. All fields for the added tape device are inactive until you select the first field, typically the name field. After you select any field for the added tape device, all fields are enabled. All fields for the added tape device are inactive until you specify information for the Tape name field, then all fields are enabled.
Remove
Click Remove to remove the content from the first set of tape device fields and disable all fields after the Tape Name field. If applied to an added tape device on the page, this action removes the entire set of fields for the added device.
