Fields

Tape name
Select a predefined tape device from the list provided or manually specify a unique name for a custom tape device. The name you specify must consist of 1 - 64 characters. You can use characters of A - Z and a - z, numbers of 0 - 9, plus the underscore (_) character. A name cannot begin with a number and cannot be a PowerHA® reserved word.

If you choose a predefined tape device, PowerHA SystemMirror defines the Tape device property, the Start script property, and the Stop script property for you.

Tape device
Specify the path and file name of the tape special file. If the first character is not a forward slash (/), the wizard adds /dev/ to the beginning of the path that you specify.
Start script
Specify the full path and file name of the program to use to start the tape device, along with any additional arguments to pass 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 use to stop the tape device, along with any additional arguments to pass 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.
