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.
