Devclassname

Type the name of the device class to be defined in the Device class name field. The maximum length of the device class name is 30 characters.


Servername

Type the name of the server in the Server name field.

Considerations:


Mountlimit

Type the maximum number of volumes that can be simultaneously open for input/output in the Mountlimit field. Specify an integer in the range of 0 to 256, inclusive.

Default: 1


Mountretention

Type the amount of time, in minutes, to retain an idle sequential access volume before dismounting it in the Mount Retention field. Specify an integer in the range of 0 to 9999, inclusive.

Default: 60


Maxcapacity

Type the maximum size that objects can be when created on the target server in the Maximum capacity field. Specify an integer followed by a scale factor.

Default: 500M

Scale factors and their meanings are:

K Kilobyte
M Megabyte
G Gigabyte

Prefix

Default: ADSM

Considerations:


Retryperiod

Type the interval in minutes over which the server should attempt to contact a target server in the event that there is a suspected communications failure, in the Retry period field.

Default: 10
