To define a Centera device class, first complete the following fields and then click Finish, or click Cancel to end this task.
Enter the name of the device class to be defined. This parameter is required. The maximum length of the device class name is 30 characters.
Enter the IP address or addresses of the Centera storage device and, optionally, the path and name of one Pool Entry Authorization (PEA) file. Ensure that the PEA file is stored on the system running the Tivoli Storage Manager server.
The IP address must be specified in the dotted decimal format ( for example, 9.10.111.222). You can specify multiple IP addresses by separating the addresses with commas and no intervening spaces (for example, 9.10.111.222,9.10.111.223). If you specify a PEA file path and name, they must follow the IP address or addresses. Separate the two kinds of information using the "?" character (IP_address_or_addresses?PEA_filePath_fileName).
Enter the minimum size for Centera volumes assigned to a storage pool in this
device class. This value represents the minimum amount of data stored on a
Centera volume before the Tivoli Storage Manager server marks it full. Centera volumes will continue to accept data until the minimum amount of data
has been stored. This parameter is optional.
The following are possible values:
100M | Specifies that the minimum capacity is 100M (100MB). This is the default value. |
size | The minimum value allowed is 1M (1MB). The maximum value allowed is 128G (128GB). |
The value must be an integer followed by one of these units:
K | Kilobyte. |
M | Megabyte |
G | Gigabyte |
Enter the maximum number of volumes that can be simultaneously open for input and output. This parameter is optional.
The following are possible values:
1 | Specifies that only one volume at a time can be open for input and output. This is the default value. |
number | Specifies the maximum number of volumes that can be simultaneously open for input and output. You can specify any number greater than 1, however, the sum of all mount limit values for all device classes assigned to the same Centera should not exceed the maximum number of sessions allowed by Centera. |
