Use this page to define and configure one or more shared
tape resources for the resource group.
You can configure a Small Computer System Interface
(SCSI) or a Fibre Channel tape drive as a cluster resource in a nonconcurrent
resource group. As part of a resource group, the tape drive is highly
available to all nodes defined for the resource group. 
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.
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. The wizard does not activate any fields
for the added tape device until you specify information for the Tape
name field.
- 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.
