1.$ SET DEVICE/SPOOLED=(LPA0) LPA0: In this example, the /SPOOLED qualifier requests that the printer queue LPA0 be spooled to an intermediate disk before files directed to the disk are printed. Because no intermediate disk was specified, the intermediate disk defaults to SYS$DISK. 2.$ SET DEVICE/ERROR_LOGGING DKB2: The SET DEVICE command in this example requests that all device errors reported on device DKB2 be logged in the error log file. 3.$ SET DEVICE/NOAVAILABLE DRA0: The SET DEVICE command in this example prevents any attempt to mount a disk on device DRA0. 4.$ SET DEVICE/DUAL_PORT DRA0: The SET DEVICE command in this example enables the dual port seize logic in device DRA0. 5.$ SET DEVICE/PREFERRED_CPU=1 PNA0 The Fast Path port PNA0 is assigned to CPU 1, and the User Preferred CPU is set to 1. 6.$ SET DEVICE/NOPREFERRED_CPU PNA0 The port PNA0 will have the User Preferred CPU cleared, but will remain a Fast Path port, with CPU 1 as its current preferred CPU. 7.$ SET DEVICE/PREFERRED_CPU=(0,1,2) PNA0 The operating system selects CPU 0,1, or 2 as the preferred CPU for Fast Path port PNA0, and sets its User Preferred CPU to the selected CPU. 8.$ SET DEVICE $1$DGA1001:/PATH=PGB0.0123-4567-89AB-CDEF/ENABLE In this example, a request is made to enable path PGB0.0123-4567-89AB-CDEF as a switch path destination. No error is indicated if the path was in the enabled state prior to the request. Had the /NOENABLE option been used, the path would have been removed from switch path consideration. 9.$ SET DEVICE $1$DGA1001:/PATH=PGB0.0123-4567-89AB-CDEF/POLL In this example, a request is made to enable path PGB0.0123-4567-89AB-CDEF for polling of its continued availability as a path switch destination. Had the /NOPOLL option been used, the path would have been removed from path availability polling consideration. 10$ SET DEVICE $1$DGA1001:/PATH=PGB0.0123-4567-89AB-CDEF/SWITCH In this example, a request is made to switch from the current path to path PGB0.0123-4567-89AB-CDEF. Should the path fail, the switch algorithm of the unspecified path is used. 11$ ! Command sequence used on system 1 at site 1: $ MOUNT/SYSTEM DSA0:/SHADOW=($1$DGA0:,$1$DGA1:) TEST $ SET DEVICE/SITE=1 DSA0: $ ! $ ! Command sequence used on system 2 at site 2: $ MOUNT/SYSTEM DSA0:/SHADOW=($1$DGA0:,$1$DGA1:) TEST $ SET DEVICE/SITE=2 DSA0: $ ! $ ! Commands used on both system 1 and system 2: $ SET DEVICE/SITE=1 $1$DGA0: $ SET DEVICE/SITE=2 $1$DGA1: In this example, the system at site 1 will perform all reads from $1$DGA0, which is the physically local disk, while the system at site 2 will perform all reads from its physically local disk, $1$DGA1.
