If one needs more than 9999 logical disk devices then another
 	'controller' may be used by specifying a new device at
 	connection time:

         $ RUN SYS$SYSTEM:SYSMAN
         IO CONNECT LDA0/NOADAPTER/DRIVER=SYS$LDDRIVER
         IO CONNECT LDB0/NOADAPTER/DRIVER=SYS$LDDRIVER
         IO CONNECT LDC0/NOADAPTER/DRIVER=SYS$LDDRIVER
