Setting the Fixed/Floating Option
In SWCC, if you select the Fixed option from the Add Virtual Disk wizard, the
CCL remains assigned to that location. The Client reserves the address of the
LUN, and you cannot use the Add Virtual Disk wizard to create virtual disks.
Caution: The Fixed option works only with the Add Virtual Disk wizard. With
CLI you can still overwrite a LUN address assigned to the communications
LUN, even if the Fixed option is selected.
If you select the Floating option, you can use the LUN address currently assigned
to the communications LUN to create a virtual disk. If you use this address, your
controller automatically “floats” the CCL to another address and you lose
communication with your subsystem.
To select the fixed/floating option:
1. In the Device window, double-click the icon for your controller to display its
property sheets. If you have a dual-redundant controller configuration, you
can use the property sheets of either controller.
2. Click the Communications LUN tab.
The operating parameters for the communications LUN are displayed.
3. Click either Floating or Fixed to select it.
Note: Changes to your controller configuration require password access. The
program prompts you for the appropriate password on your first attempt to modify the
controller.
