4–34 Compaq StorageWorks HSG80 Array Controller ACS Version 8.5 Maintenance and Service Guide
Commands can be abbreviated to the minimum number of characters necessary to identify
the command. Enter a question mark (?) after a partial command to see the values that can
follow the supplied command.
For example, if DISP ? is entered, the utility will list CACHE, DEFAULT, and so forth.
(Separate “DISP” and “?” with a space.)
Upon successfully executing a command—other than HELP—VTDPY exits command
mode. Pressing Return without a command also causes VTDPY to exit command mode.
Checking Controller-to-Host Communications
Use the display host VTDPY command to see how or if the controller is communicating
with the host (see Figure 4–1). The display for ACS V8.5P differs slightly.
